I have a 94 ranger and all of a sudden it started sputtering, i can hear a vacuum leak behind the intake manifold found what appears to be a pcv valve not hooked up is that the way it's supposed to be?
View 2 RepliesI am mixed up in which fasteners I have to tighten to stop my antifreeze leak. For this, I got some pictures. Do I have to tighten these bolts? Or these? Is this the upper intake intake manifold?
I am just really lost and want to tighten the right bolts and find the torquing specs of the bolts. In the first picture, we can clearly see there is a leak there of what must be antifreeze. The stuff I have been loosing slowly over months.
'03 Ranger, 2.3L. Runs great except at idle. Code p0171. Replaced IAC, no luck.
Brake cleaner leak test definitely results in engine rpm change right around "butterfly rod" plug in front of intake manifold near no. 1 cyl. I'm pretty sure that's the problem - the plastic plug blew out. I watched a video showing repair, but it seems lacking.
I do not want to loosen up intake for access - I'd rather remove steering pump and gain some access to plug it up. There still isn't much access but, but eyeballing it, enough to plug, I think.
Three steering pump bolts came out easy. The fourth one is behind fluid line - extremely difficult to access, imo.
Somehow try to remove pump for access to intake hole, or bite the bullet and remove intake manifold for access?
I was working on my friend's '87 Ranger with 2.9 L V6, and a little bit of dirt fell into the intake manifold through the injector ports and intake ports. I should've cleaned the top of the engine with a shop vac first. Anyway, should I remove the intake manifold, or try to vacuum the bits out? It's pretty oily inside, and they might be stuck to the inside of it, so the vac might not do much. If I have to remove it, do I have to de-mesh the distributor gear to remove it, or does the distributor attach to a splined shaft? After looking at the diagrams, the answer was unclear.
View 1 RepliesSo i was thinking about buying a intake manifold for my truck and porting it and polish it. Would it be worth doing. I've decided that trying to port the heads will take up to much time and money for gaskets. Now the only reason why I am buying another stock one is so i can take my time and do it right.

View 14 RepliesJust bought this truck and no check engine light was on, went to get it smogged so I could register it and it had the following fault codes: P1443, P0401, P1131, and P1132. The truck seems to run great in my opinion and even gets really good gas mileage. There is a whistle intermittently from the intake manifold area though that is at times pretty loud.
Smog tech told me these trucks are "notorious" for the check engine light going bad and that usually the entire instrument cluster has to be replaced in order to fix it. I'm a very experienced motorcycle /small engine tech but do not have much experience with car/truck engines and especially not with emissions control systems.
Again it is a 1996 Ford Ranger 4.0 V6, 4 wheel drive STX with 185,000 miles on it. Where to start or what might be the source(s) of these error codes?
Background - I just got done changing a few things... Exhaust Manifold/gasket, battery cables, valve cover gasket, oil cooler gasket and hoses, power steering pump and hoses, and ball joints. Most of this has nothing to do with the issue that came up as I am driving it back to return it to her.
While out on the freeway, I initially notice subtle power losses and surges. These quickly escalate into almost total power loss with back firing, sputtering and much more noticeable surges in power. The check engine light was turning off then on a few times before pretty much deciding to stay on.
So I nurse it back home on back roads due to its inability to maintain freeway speeds. I proceed to check everything I touched paying special attention to the exhaust manifold and surrounding area. The new manifold came from the j/y and was barely used so I had initially just stuck with the O2 sensor that came with it; I changed this to the one the vehicle had previously been employing as it was not exhibiting these symptoms until after the job was done. I also double checked all the hoses, intake tube, wires and connectors; everything is connected.
From here, I research the method of pulling codes on OBD-1 vehicles by making the check engine light flash. It flashed a 111 and a 172 at the same time; the information I could find said the 111 means everything is normal, and the 172 suggested O2 or MAF. I am reasonably sure the O2 is not the problem so I focused on the MAF. Disconnecting it while running seemed to improve the way it idled so via the process of deduction, which also included the consideration of typical symptoms of MAF sensor failure, I proceeded to replacing the MAF sensor which amounted to little improvement.
At this moment in time the check engine light has not returned but it is clearly not in a drive-able state of being. It actually seems to have ever so slightly improved though.
Additionally, the symptoms only exist when the engine is hot and has been driven; it drives normally for 5-10 minutes until it gets to operating temperature then it starts to crap out. After changing the MAF sensor, I let it idle for 20 minutes and it was fine until about 2 minutes into the test drive.
Speculation - I am thinking spark plugs could also be a culprit as its has been forever since a tune-up but the sudden onset of this condition make me doubt this a little; it also has 8 plugs so even if one or two crapped out it should still run better than this I would think.
I noticed green coolant leaking from bottom of black, what I think is called, timing belt cover. There is 188, 000 miles, and when I changed the timing belt, I did not change the water pump, although I did change out the thermostat. I have done a lot of work on this truck in the past. I checked the oil and no signs of water or coolant mixed in. The water pump is not weeping from the top well. I rely on this truck and the way I look at it is I may just keep driving it until it goes kaput (its real beat up). Should I go to an auto parts store and see if I can buy some sealant. I would guess it is either the water pump or maybe the timing cover gasket? I have inspected all hoses, and I see nothing. The leak must be coming from somewhere under that black, plastic cover. I am capable and willing to do just about anything other than perhaps a full engine pull, although I have the wherewithal to do that too if absolutely necessary.
View 9 Replies I've got a 1997 F150 with the 4.2L V6. Before I got it last summer I did some research, but apparently missed the issue with the intake manifold gasket leaks on these early engines. It seems to be a very slow leak, but obviously I want to get it fixed. I called Ford to see if it had had the recall work done on it, but all they could tell me is that there wasn't an open recall on my truck (with the exception of the recent fuel tank strap recall). Their system apparently only goes back 10 years, so they couldn't even see the freakin' recall. So, I've got a few questions:
1) I know I didn't post much info, but does this seem like an intake manifold leak?
2) Are there any special tools needed to change out the gasket myself?
3) Can you all recommend any replacement gaskets? I found a few different manufacturers of gaskets, but I'm sure some are better than others.
4) Can this issue cause the computer to throw the loose gas cap code (P0455 if I recall correctly).
5) Would it be worth it to just get a new truck? I really wanted a diesel in the first place, but I also hate to give up on a nice truck with only 115,000 miles.
I have a 2006 F150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head. This is on the drivers side directly under the thermostat housing. The t-stat housing is dry and the hoses all appear dry. It's just wet right at the gasket where the manifold joins the head. Reservoir is still normal so it's not leaking too much just yet.
I searched this site and youtube but didn't find any other posts. Lots of problems with older trucks with composite manifolds but nothing for this one. It looks like a part of the bottom of the manifold is plastic but the entire top and where it is leaking is all aluminum.
It seems odd that this would start in the winter time just driving back and forth to work (no load). And, yes the antifreeze is good. Just wondering if this is a known issue with this truck. Is it just a matter of replacing the gaskets or is there some other flaw I should be concerned about?
I have a 2003 Explorer with the 4.0 K motor. It has a vacuum leak and the check engine light will come on from time to time. My work buddy has a high end computer and it showed that the driver side bank was running lean. The computer showed the O2 sensors to be working fine, and I replaced the PCV valve. All other vacuum line appear to be in good condition and I tried the spray test with the break cleaner with the motor running. This is leading me to believe the air intake gaskets where due for replacement. Here is my problem, I can not get the last bolt out of the plenum. The one on the driver side up against the fire wall. I tried to remove the cowl in order to get a straight shot at it but I can not get the seem seal to break free.
View 4 RepliesIf you have a coolant leak at the y hose for the intake manifold and the thermostat, make sure you replace the upper radiator hose as well as the y hose.
View 3 RepliesI have a 1999 Ford Expedition. A couple of days ago The engine started losing coolant as soon as the engine cooled. I replaced the coolant only to lose it again when the engine cooled. I was told that it is more likely the intake manifold gaskets leaking. It seems they are right. What is the cost to repair if I take it to a mechanic?
View 1 RepliesI have a 2001 F150 Super Crew 5.4. I had a leak where the water transfer connects to the intake manifold. I decided to get a new manifold rather than trying to repair it. The new manifold from Dorman came and the gaskets were built into the manifold. I torqued the manifold to specs. I replaced everything and it starts fine.
I can hear what sounds like a leak, but can't find anything. I checked every hose that is connected and they are all snug and connected. I had the check engine light checked and it said it was running lean on both sides (p0174, p0171). Also a p0122. I thought something might have damaged the Throttle Body Position Sensor, so I replaced it...but no change.
I'm still driving it everyday because I need to. It won't change gears so smoothly sometimes. The most noticeable problem is that the A/C doesn't work. It just blows hot air. And the worst part about it is...it does it even when the air isn't turned on! I just go around with the windows down...in 95+ degree heat...with hot air blowing!
This is my first time to attempt a manifold change out. What I should check?
Can oil leak out of Intake Manifold? i have Oil around lower intake manifold gasket. is this serious issue?
View 11 RepliesMy friend and I are working on her '03 1.8t and I noticed a huge oil leak under the intake manifold. It looks like there's a tube that has broken off and is now just spewing oil all over the place. I tried to get pics the best I could, so here they are....
I'd imagine its something that needs to be fixed asap.
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.
When I got my 60K service last weekend, the dealer called me and explained that I had a "very small internal leak fro an emissions canister that was leaking into the intake/manifold". He said something like that. He also said that it doesn't do anything to the performance of the car, but that the leak will increase over time and will throw a MIL.
View 6 RepliesWhen I'm driving it starts to cutout (but it never dies) and it won't stop cutting out until I floor it and then it's fine for a little bit and it starts doing it again.
View 1 Replies'86 Ranger, 2.3L, Automatic transmission.
Been having a sputtering/rough running situation once warmed up, replaced every so often with open loop smooth running. Lately, have had several occasions where the truck stalls and will not restart after a hard right turn (fuel pump powers up, tho) After 30 or so minutes of repose, truck will restart and run.
Recent History:
During the last 1-1/2 years, had cylinder head rebuilt and reinstalled. Had to run it all winter w/o EGR tube attached because of bad fitting at exhaust manifold. Replaced the fitting last spring and replaced cat back exhaust system. Had manifold hole plugged with pipe plug all winter. Have had a diagnosis of poor compression in the past, have not rechecked compression since head rebuild, but did have a noticable increase in power.
Have checked base ignition timing and it is correct. Valve timing appears to be as it should be. Have not had the opportunity to check for spark during one of the breakdowns, since I had no tools and it was night time.
The codes:
Early in Fall, got 14, 21, 24, 34. The 14 particularly interested me, as it suggests ignition problems.
Just before pulling the distributor, I checked codes again; 14 had disappeared as did 34 (EGR issues I resolved above) but I still got 21 (coolant temp out of range) and 41 (no HEGO switch) So I left the distributor alone and replace the HEGO sensor and cleared codes.
Last code check, just got 21(coolant temp sensor voltage out of range) and 24(air charge or Vane air temp voltage out of range) There is very little heat on cold days, full radiator and I've "burped" the cylinder head on an incline more than once chasing trapped air.
I'm suspicious of the TIF module, since the stalling is after warm up and self corrects. It was replaced once perhaps 12 years ago.
