Ford - Explorer :: 2003 - Vacuum Leak And CEL On - Air Intake Gasket Replacement
Aug 28, 2014
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.

I have a 98 f150 4.6 4x4 with 175.000 miles, I suspected the intake gasket is leaking, I'v never done this before. What is involved with this type of repair? Will the intake gasket leak bad enough to leak antifreeze on the floor? Is it okay to continue to drive with this problem? Bad weather is on the way.

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 took my Monte in for the annual Missouri Safety Inspection. Note: I had no known problems with my 2003 Monte SS 117K Miles. After the inspection, which passed, I was informed of a variety of problems: Intake Manifold Gasket Replacement, Valve Cover Gasket w/Intake replacement, Thermostat w/Intake Removal, Fuel Injector O-Rings w/Intake Removal.
My question is should I have all of this done? It's not cheap..roughly 1000 bucks. I know very little about this and I don't want to just tell my mechanic to do it without some research. Are these common problems with Monte's of this age/mileage and just part of the cost of owning this car. I am the original owner and have avoiding costly repairs/maintenance..it's been a great car.

Well, I decided to take on the dreaded task of replacing the lower manifold intake gaskets and put in new isolator bolts. It was a major undertaking, and when I finally finished the oil change and fired up the car, it sounded fine. Then I checked under the hood.
I saw coolant spurting out the side of one of the hose connections that I had to take off and put back on. I thought the gasket on it looked pretty worn, but wasn't expecting this!
Unfortunately I don't know the name of the hose connection to pick up a gasket at the store ... it's the larger lower hose that is bolted on to the lower intake, not the hose slightly above it that has the plastic clips.
What is the name of this hose connection so I can try and find one at the store? It's a 2003 Windstar model.

Vehicle 2007 Ford Explorer Sport Trac with 4.6L
Ok, just did a head gasket replacement. Everything is now hooked back up. Now when we try to restart the car, we get lights, but nothing from the starter. Also the OBDII code puller can't communicate with the car. Also the security light flashes very fast when you try to start.

I'm having a little bit of trouble finding the cause of a minor problem on my 06 Explorer with the 4.0 V6 engine. When the engine is running cold at idle, it runs a bit rough and idle speed is high as well. When fully warm, the engine runs and idles fine. I hooked up a scan tool and there are no pending or stored codes. The live data looks ok except the long term fuel trim which is at about +10% on both banks during idle, indicating a lean condition. Short term fuel is right around zero. The MAF and TPS values seem to respond fine when applying steady throttle.
So I assume there must be a fairly small vacuum leak somewhere that the PCM is able to compensate for since the long term is only at 10. I didn't see anything obviously wrong, the vacuum lines look fine along the passenger side near the firewall. I sprayed a bit of throttle cleaner along the hoses, intake manifold and gasket area, but could not spot any vacuum leaks. Any other common areas to check for leaks on the 4.0 V6? Perhaps there is something I am missing?

I popped a code this morning PO442 emission control evap [small leak]. Would this be a vacuum hose leak? I did both heads about a month ago. Any way to narrow down the troubleshooting on this problem?

My 97 f150 5.4 started missing on 5,6 it had antifreeze on top of the spark plugs but i cant figure out where its coming from my truck has been loosing coolant and it seems like the system is holding pressure because every time i take the cap off the radiator overfill i can hear it hissing then i see the antifreeze level plummet there's no visible leaks that i have seen when the truck is running an missing it steams out the exhaust but when its no missing it doesn't seem to be there's no milky oil or anything the thermostat doesn't seem to be leaking either the truck has over heated a couple times due to the antifreeze disappearing or the temp wont move at all then it shoots all the way to hot and cools down within seconds to normal i just put a new thermostat in. Also it sometimes misses on 4 and my exhaust smells like straight gas i put 4 gallons in it got 29 miles out of it .

I have a 03 5.4 F150 SCrew... The intake was leaking on the passenger side (water outlet tube meets plastic).
Putting in the Dorman replacement and noticed that the front cylinder drivers side (#5) had a decent amount of coolant in it.. None of the others did. I've drained the coolant already and was wondering should I just put this back together and see?
The water outlet crossing has a hole right next to this cylinder and I can't see any cracks and not sure if the gaskets were leaking under it.
Seems like if the head gasket was blown I would see it in more cylinders? It never smoked or run bad before I got this leak... Drove it maybe 10 miles with it leaking out onto Cyl#1. Ran fine, never missed.
I just don't want to put this back together if the head gasket is blown but I don't know what to do.

Got 2006 Explorer back fron trans rebuild and probably unrelated but started getting P1405 (Large vacuum leak) and alternating "replace gas cap" errors. When I installed a new gas cap, error went from large vacuum leak -which I checked for on engine and found none using smoke test- to loose gas cap. So next, I changed the emission system valve which is right up front on rt. side of engine looking into engine bay. Now, error has returned to large vacuum leak. So new gas cap and valve. Error does not come back immediately after clearing. Takes about a week and then either get SES light and large vacuum leak error or just picture of gas cap on dash error. Note that when I remove gas cap, I no longer hear the "whooosh" of releasing a vacuum. Assume now it is in back by spare tire where I need to be looking. I note on emission valve that there is a schrader valve for testing vacuum....

just got finished putting her back together from a blown intake manifold gasket and run for a few miles to get rid of any cob webs and then my battery light comes on. just replaced the battery last week. and I tested the alternator and it charging at 14.5 volts bat reads when disconnected 12.9 volts so I am not sure why my battery light will come on.

I have been having some issues with my 97 ford f150 4.6 liter, started out running rough, then hydrolocked with no serious damage, blown intake manifold gasket, fixed that, alternator over charging do to bad voltage regulator, fixed that. and airbag code 52, still working on that, as well as failure to connect when trying to do diagnostic scan. now I am wondering if the engine diagnostic is still even working. still running good just a very slight vibration when warms up. I am not getting any code. or my check engine light is not showing any codes. What I want to do is force a code. What would be the safest way to force a code or force engine light to give a code?

2004 camry, oil pan gasket replacement required? Mine is leaking.
Was there anything difficult about it? Any special notes or tricks about replacing it? Seems like it would be a simple job.

I was surprised by a leak and identified where the water was coming from, the bottom of my vehicle. It's from a gasket or seal on the front of the pan near the flywheel. 1994 Ford Explorer 4X4.

I recently had my gasket replaced and 24 hours later, there were several oil leaks in my driveway and oil dripping from my 99 Toyota Corolla every time I parked. I brought it back to the shop this am since they were no open on Saturday. My question is they stated it might just be a loose filter and/or a bad filter.

I am about to replace the intake manifold and gaskets. I know all of that process, but first question is if there is anything i should do whilst in there. Second question; what can I do with my intake to get more power? Mainly just kind of wondering before I get my parts ordered.

It has been since the 80's that I have attempted to do any work on a vehicle. How do I find a vacuum leak and where is my vacuum canister. I am assuming that it is a vacuum leak for anytime my engine has a load on it the air stops coming out of the dash vents and goes to the defrost vents. I have an 2000 F150 with the large engine with about 112,000 miles.
