Ford Ranger / B-Series :: 1998 - Exhaust Leak Sound Under Hood?
Apr 13, 2013
I have a 98 Ranger 3.0 with a standard transmission. The truck has 240,500 miles so far. It runs just as good as the day I got it 11 years ago, doesn't use any oil and still gets 23 MPG. Last fall, it developed what sounds like an exhaust leak under the hood. It seems to be coming from the area of the EGR valve. The trouble is that I can't feel it or smell it. I have carefully felt the entire length of the tube running from the EGR to the exhaust manifold and cannot feel any leaks. There is no soot or any other evidence of an exhaust leak.
The noise isn't there for the first minute or so that the truck is running. I would think that if I had a cracked manifold or some other such leak, it would be worse when the engine is cold but this is not the case for me. It is most noticeable when pulling a hill as slow speeds in a higher gear. I have checked for codes (no CEL) and there are none. When I first heard it I figured that I would wait until it gets a little worse and I would be able to find it. Its been been over 8 months now it has remained the same.

1998 ranger 5spd... I have 117k miles on this little ranger and I recently took it on a little trip and since that trip it has a ticking noise under the hood as if the lifters were sticking. I believe it has hydrolic lifters in it. I put some sea foam in it 200 miles ago and changed the oil about 50 miles ago. I used Valvoline full synthetic and it seems like it has lessened the tick and it drives a lot smoother, in my opinion. Is there any thing else I can do to relieve that ticking? It is more noticeable when the engine first starts and is louder if i push down harder on the gas. It is not preset if i do not put that much pressure on the gas.

The problem I have is the truck won't move in o/d. If I put it in revers 1,and 2 it works. A little back ground. 4 years ago the trans went out of my 95 4.0 4x4, had it rebuilt so it has 0 miles on it. It got really cold that winter had lots of trouble getting the trans and torque converter lined up. motor went bad on me. A few months ago finally had some money to spend bought a 98 explorer sport with a 4.0 x code motor. the motor runs fine apart from an oil leak and an exhaust leak. the exhaust leak is no big deal I just haven't gotten the system tight yet.

I bought a '98. At the front passenger side of the engine, the injector rail is leaking fuel (a fair stream of it). I have done some googling, and browsing around the forums, and can't find much in the way of specific info on where to start with this.
Whatever the device at the front of the rail - Without digging too far, it seems that the leak is coming just below it.
Questions:
Am I obliged to change injectors with the rail?
What is involved with changing the rail? Removing upper intake only? At all?
What is the box shaped device at the front of the rail, passenger side? Test port? Pressure Regulator? Both?
I won't have a chance to work on this again until next weekend, but thought I'd try to do some homework beforehand.

I just had trans rebuilt in my 98 4x4 4.0 ranger I thought while they had the trans out go ahead and replace rear seal. Got the truck back leaking bad carried it back they claim to have replaced it twice while they had it and guaranteed it was not leaking they say the leak is from the oil pan so I'm gonna pull the motor this week. Question is: can make an offset rear seal I still believe this is the problem. Which oil pan gasket to use.

My ranger decided to start leaking fuel somewhere probably a few weeks ago. I can smell it whenever I start the motor, and sometimes while driving with the windows down. Last night, I finally looked into the problem. I took the intake air hose off. The hose, air filter, and whole intake smells like gas. I'm thinking that shouldn't be the case on a fuel injected engine. After seeing some people talk about the Fuel Pressure Regulator go bad, I pulled the vacuum line off of it, and it has a very strong gas smell. I don't see any gas coming out of it, though, even with the motor running. Everything I read says if the regulator is bad, then gas should come out of the vacuum line. Is there another check I can do on it to confirm this is the problem? Is there somewhere else I should be looking? It got two new heads right before this problem started, so its quite possible I knocked something putting it back together.

I have a 2003 ford ranger 2.3 vin d 5 speed, this truck originally... Took it in for wires plugs front brakes fuel filter battery and added a small cold air intake. We discovered a valve cover leak and while repairing guy drops a screw into a valve and when finished he started it lodged the screw between the valve, shearing off a cam sprocket bolt. Throwing the timing. 2 valves on the exhaust side were bent and replaced. no damage to the head.
Timing was reset and the truck was running. 2 days later truck is running/had a hint of exhaust smell then started bogging dying and shaking, at which time we got an 02 bank2 lean code and fixed that. it cleared code and didn't fix it. From there we replaced coil, imrc intake bc of a crack, tried and check all vacuum, reset the timing. Timing would slip before but no longer than 10 minutes every time truck started.
Found the hole in the timing cover that holds the bolt to torque? to harmonic balancer was broke. replaced along with the diamond washers and cam sprocket bolts. timing finally held crank sensor was adjusted. truck came home for one day running good, we had removed the cold air intake and replaced the factory air intake. next day it was so slow outta first gear, you must baby the throttle, if you floor It, it sputters and kinda pops, truck stays slow all the way to about 10 mph and 2000rpm then it begins grabbing speed, 3000rpm is where this truck shifts the best, 2nd is better, third better than that.
As rpm increase the truck runs better, it idles steady at 1100-1200rpm at stops with an audible miss and then struggles again on takeoff. Here what im wondering, the truck has an abs sensor that just came on, but no codes showing now.tomorrow I wil run matko determinator 3.0 on it. and test the catalytic converter. first how do I check the timing belt to see if it stretched? do these trucks store the p.i.d.s. koer or kams that could cause one, all, or any of this and if so do I have to have it flashed from ford or can you manually do this without a drive cycle test.

I have a 1998 ranger 2.5L engine. I took it to a Ford garage and they told me I have a rod knock..........I took it also to a good mechanic and he said the sound is coming from the lifters.
There is 172000 miles on motor and the noise started at 131000, and is getting worse. Should I drive it till it blows, or is there a way to tell what the problem is?

I am looking over a 1998 Ford Ranger. Very low miles for its age (67,000) and kept in very good shape. When I took it for a drive, I noted an issue.
- there's a whining sound in first gear and reverse that varies according to the engine RPMs. I thought it might be the power steering pump, as that whined when I turned the wheel.
However, the noise went away when I shifted to the higher gears. Been a while since I drove a stick - my Bug back in 2003, IIRC.
What I might be getting into? I really like this machine, aside from that issue, and I would like to nail the problem down ASAP...

I have had an exhaust leak under the hood of my 09' F150, XLT, 4.6 3V for some time now and decided to get it checked out. I took to the local stealer and as i suspected its the manifolds. There are 4 studs on the left and one stud on the right sheared off. Ford quoted $1400 for replacing both mainfolds and extracting the broken studs. This would give me the exact same manifolds that were on the truck from the factory and started leaking at 78,000 miles.
So I decided to take the truck to a local speed shop that I have used in the past for other things. The mechanic there said to just buy a high quality set of stainless headers, stage 8 locking fasteners, and copper gaskets. He will install. I went with JBA shortys from AutoAnything.com and the mentioned hardware from Jegs.
So basically for around $100 more I get headers that probably will last the life of the truck. I am quite displeased with the exhaust issues that Ford has had and known about for over 20 years. The service manager at Ford said they replace manifolds with broken studs on a regular basis. He also said it was a wise choice to go with the headers instead of the manifolds even though they will not install them. That says a lot about the confidence of the Ford service department in their parts and vehicle designs.
Its a little sad that a 6 year old truck with only 78,000 miles....

I have a 94 ranger 4L. I am looking for a more loud exhaust sound in/outside the truck and at idle. I have had a cherry bomb turbo on it and it was ok but not loud enough for my liking. I just picked up a flowmaster 40 2 days ago and it sounds good but again just not loud enough for my taste and kinda a lot more. I was looking for a louder muffler that is not a glasspack and would like to stay under like 80 or so.
I also thought about getting a high flow cat which i think might make some more sound but was not sure. Im running the stock pipe which is 2" and end in back of the wheel on the right. I look at the Hooker Headers Maximum Flow Muffler which i thought would be louder b/c it's more straight through the muffler so it would put off more sound better. What would u recommend for something more loud ?

Driving home from work (a 30 minute hwy cruise) I had to stop for a traffic light. As was sitting there I hear a thumping noise from under the hood, otherwise it was running the same as always. Got it home and I didn't hear it anymore, looked under the hood while idling, seen nothing, shut it off. top rad hose had a slight amount of pressure, started it and it quickly built pressure and felt a rhythmic thumping in hose and it got fricking hot quickly. I figure either a head gasket or cracked head.
I just recently did an aggressive cooling system flush using Prestone heavy duty cooling system flush (can only get this at a dealer) because the previous own neglected it, and it blew a head gasket, tons of rust inside when I did it. I'm gonna borrow a tester to check for exhaust gas in the cooling system and what did it end up being? The guy I bought it from (the previous owners mechanic) put 1 or 2 head gaskets on it.

My son's 2001 LeSabre (3800 N/A) was smoking under the hood and the odor was entering the cabin. I decided it was likely due to coolant and oil leaks from the valve covers and manifold gaskets as well as a crack in the upper radiator hose. So I replaced all the gaskets and hoses and cleaned it up some.
After a test drive, smoke still coming from under hood. It appeared to come from the exhaust crossover joints (mainly front) and possibly from the seam on the crossover "shroud". I suspected some rust damage to the crossover, so pulled it out. (And spent my Sunday digging out a broken bolt. )
I don't see any visible rust on the crossover (but can't inspect the entire thing visually). Could it be a clogged catalytic converter causing back pressure and the leak? Or is it more likely something under the hood like a head gasket. (I hope not. )

1991 2.3 l. Thought I had an exhaust manifold Leak. Replaced gasket. New gasket didn't work. Removed gasket and mounted manifold to engine metal to metal, still and noise. Installed New manifold with gasket. Still same noise. Am thinking noise not coming from manifold. Torqued all bolts to spec. Could it be lifters .

My battery went flat and to compound my misery, when I went to open the hood, the cable was snapped. How I can open the hood without using the release cable ? I'd rather not have to pay for it to be taken to the mechanic and then also pay to have the battery changed !

fuse #11 in the battery junction box under hood keeps blowing, the last time I put a fuse in it blew immediately, key was off and lights off. Fuse is for parking lights, dash light and I/P(whatever that is) and switch illumination lights. I have to start following all wires to find bad spot. May just put in piece of metal and watch for smoke...

I have a 97 Ford Ranger / 2.3L / 4 cylinder (L4) / 5 speed manual / XL Supercab / 140k miles. I had been having some Check Engine issues and ran rough in town stop light to stop light. But was fine on the highway.
On several visits to the parts store, their OBD tester showed:
PO303 (Cyl 3 misfire detected)
PO141 Bank 1 Sensor 2 O2 Sensor (heater circuit malfunction)
PO171 Bank 1 Combustion Too Lean (the most recent new code to show up)
And the following would show up sometimes, but other times not:
PO 402 EGR Flow - Excessive Detected
P1409 EVR (I cant remember the exact error message for this)
Regards the PO141 code, O'Reilly's sold me a Bosch O2 Sensor (Bosch 15719) and the sales rep told me it was the sensor closer to the engine. And with the attached cable length on the sensor showed was indeed the sensor closest to the engine. But I've been advised the Sensor 2 is for the 'downstream' sensor, furthest away from the engine. And the other sensor, that I replaced is the upstream sensor. And the error continued.
Then back issues showed up and I had back surgery this past year and thus drove the vehicle sparingly. Never resolving the check engine issues. (My bad). Ran on the highway ran fairly well. But recently noticed longer acceleration times and unable to top 65 in 5th gear. I bought spark plugs and plug wires and had plans to change next week.
Yesterday as driving down the Interstate, was 90 miles into my trip, I noticed loss of power even in fourth gear. (note it was the hottest day of the year at 100F). It seemed I used more gas than usual for that distance. I stopped for gas on the Interstate and power seemed to improve. Then about 130 miles into my trip I hit some heavy stop and go traffic, and wasn't able to keep an idle and the engine died numerous times if/when I didn't give it gas at a dead stop. The heavy stop and go heavy traffic and the issues persisted for a half hour for more than five miles. Then when traffic opened up the truck seemed to have a bit more power in 4th gear again. And up to that time all my dash gauges were showing fine. Then a couple miles or so down the interstate, driving 65mph in the inside lane, the check engine light started flashing quickly. And at the same time a sudden loss of power, rough sounding engine with heavy white smoke coming under the hood. And looked back in rear view mirror, with nothing but heavy white smoke. Managed to cross three lanes in heavy traffic and was able the vehicle to the outside emergency lane, finally coming to a stop.
Looked under the hood and saw oil dripping everywhere but with all the oil everywhere I could not find a prime source. Looked like the oil came from the top end of the engine and dripped down. Measured the oil at the dipstick and it seemed like I was at least a quart plus down (I checked the oil before I left on the trip). And it didn't look like any water was in the oil. And my radiator overflow tank was at the proper level. So I figured I lost all that oil during that period of "white smoke".
So had my vehicle towed home. Today in daylight, I did some more inspection and removed the air intake system (hoses and canister) from the air filter to the throttle body. There was significant oil up to the canister piece that fits on the air filter canister (but no oil in the actual air filter), and significant oil inside all the hoses up to inside the throttle body (up to the butterfly which I could see),
When I disconnected these hoses I noticed the blow-by hose connected to the intake hose system was not connected to anything. And a tube opening on the valve cover was open without the a blow-by hose attached and, with no clamp. So I assume all that oil and came out of that blow-by tube on the valve cover, (white smoke created by hot oil hitting the engine).
So appears to me that its not a blown head gasket or worse, which I first feared.
I have the vehicle parked at home.
QUESTIONS: So what are the suggested steps to troubleshoot and repair? Besides reattaching everything and putting a clamp on the blow by hose? And installing new spark plugs and plug wires. I previously replaced plug wires around 60k, even though the manual recommended 100k mile replacement. (And a couple yeas back I had the dealer replace the PCV, which was recommended in the manual and included in the warranty. The timing of the initial check engine lights appeared shortly thereafter).
Is there suppose to be a large amount of oil in the air intake system after an incident like this and should I try to clean/flush out the hoses and the inline canister?
When I disconnected the inline canister from the hoses in the air intake system, unfortunately I failed to document the direction which the canister goes. It has outside markings "ADP with a forward arrow with some horizontal lines, and then at the other end upside down markings with a greater sign PP less than sign. Should the forward arrow point toward the throttle body or toward the air filter (I'm thinking in the direction of air flow, toward the throttle body). I've taken some photos of the engine with air intake hose system unattached, if that might work...

Since putting my new exhaust on (post-cat)... I've had this "ping" occasionally from the exhaust. Sounds as if someone is taking a small metal bar and hitting the exhaust. Random intervals, pretty loud, does it whether the engine is off or on. Only does it when warmed up though. I can't narrow it down due to the randomness of it.
