Ford Escape / Hybrid :: 2004 V6 - Misfire / Valve Cover Seal Was Leaking
May 6, 2015
My wife has a 2004 escape v6 (3.0L). The valve cover seal was leaking so I decided, why not change the plugs since I'm already going to have the intake manifold off.
I got down there, replaced the seal (just the front side, didn't want to disassemble something that wasn't broke) and then replaced all 6 plugs and boots (with springs). Fired it up and everything seemed fine. She went to drive to work and the CEL started to flash. I read the code and there were 4 (Don't remember exactly what they were), but it was a combination of things resulting from a misfire in cylinder 4. Since it was one of the front ones. I just pulled the plugged and replaced it hoping I had gotten a dud from the factory. Nope, still doing it.
I didn't take off the fuel lines, just the air intake on the top. I did not change the coils, but everything was running fine before I changed plugs so logic would dictate it is something I did. Only seems to misfire at higher speeds. Also, her battery light randomly comes on, but the battery and alternator test good. This has been happening a while.

After reading some posts I think my passat could have the cam seal and valve cover gasket leaking. I smell burning oil when stopped. How much should this repair cost if I go to an indy repair shop?

In this video I go over what is becoming more and more of an issue with this generation of Escapes due to the poor lift gate glass seal leaking rain water into the latch and electronics in the lift gate. I go over the cause, how to gain access, diagnosis, and of course repair.

My g/f's 2004 Ford Escape (3.0L V6 AWD 112,000mi) is acting up. After a full day of sitting, with the second half of it raining steadily, she was driving her Escape and it was acting funny (miss-firing, she said). The engine light came on and soon began blinking. She got to my house shortly after it started this. We left it and I drove for the day. Later that night, I drove it and it seemed fine. The engine light was on, but not flashing anymore.
The next day I took it my friend that was a Saturn mechanic and now working at a KIA dealership (same owner as the former Saturn and current Buick/GMC and Chevy Dealer). It ran fine for me. So he tries to scan it, his Mac Tools scanner won't read it. The KIA scanner wouldn't read it. I drove it the Ford dealer up the road. They said they couldn't get to it until after lunch, I just want the codes read. They re-iterated, and I told them to pound salt and went to an independent shop where I know a guy. They read it right away for me. "Mis-fire on start-up" & "Cylinder 4 Mis-fire." were the two codes stored. He cleared them.
She got the tune up basics (plugs, wires, air filter, etc) and did the complete tune-up herself yesterday. (I was impressed). She put 94 in the tank and some fuel system cleaner in it as well. She said there's been no change and today I finally saw what it was doing. Sometimes during idling at a stop light, the RPMs will drop to almost zero, the lights dim but so far it has not stalled. It'll do this for several seconds, then correct itself and idle normally.
Currently, the engine light has not come back on. She's thinking coil pack (each cylinder has a coil on these engines) on #4. She wants to switch it out with #1 and see if the problem follows. I think that might uncover the cause, or it could be the battery. It's the original, never been replaced and has a lot of miles on it, but it survived this past winter, without trouble. In my experience, most batteries crap out due to age in the fall when the cold snaps start.

How hard is it to replace the front diff cover seal in an 03? Mine is leaking like a sieve... On a better note, it's the only leak I could find under my new-to-me Explorer.
Also found a broken coil spring in the rear, explains why it's leaning to one side. That is getting fixed later this week.

Passenger side valve cover leaking. My local parts stores have two brands.
Fel-Pro and MAHLE Original.
Any comments, preferences, anecdotes? I don't want to do this job twice.

My 2010 Santa Fe is leaking oil. I bought it in April & it has under 8,000 miles. After parking the car, I see oil spots that range in size from a Silver Dollar to a CD after a few hours.
First, the dealer said it was a cracked oil filter cap, so they replaced that...I brought it home and it was still leaking.
Brought it back to the dealer, and now they are saying the Timing Chain Cover Seal is leaking.

I had the front timing chain cover replaced, ever since it hasn't started. It would turn over fast a couple times and then drag and then repeat.
Found out the "Tone ring" was warped, it's been replaced and now it just turns over and over and no start but it doesn't drag anymore.
We can smell the fuel, and pulled a plug and can see spark while turning over and I was told fuel came out the plug hole so there is fuel there.
Tried a new cam sensor, crank sensor and battery and no change. Is there something else in the removal and replacement of the front timing chain cover that could be causing this?
I'm not a huge believer in coincidence as the vehicle was running great before this job.

Replacing part 9C915 ?
"CODE P0443 canister purge fault" diagnosed....
Found: EVAP PURGE FLOW VALVE STICKING
Recommending: "Diag, Replace sensor then retest" ....
They want to install a new 9C915 which they called in hand writing a Canister purge sensor but I've seen it called a canister purge valve on another thread by FIREME who puts 9C915 as "toward the driver's headlight assembly, near the radiator. You'll need an 8mm socket to remove it"...

Have a 2012 gas powered Escape XLT, 2.5L 4 cylinder.
I need to replace the evap purge valve. Looking at youtube videos and from other posts it seems easy to replace. My problem is where is it located on this Escape?
Is it under the hood or underneath the driver's side? This is just the valve mind you, not the canister in the back.

Found a tee on the heater hose leaks when it warms up. Appears the PO had noticed it but put a hose over it and now is leaking around behind the valve cover. This is a hard plastic line around 5/16. No online parts show it as being available. Is there a fix for this ?
I would bet several others have had this problem as it lays right on top of the flange of the valve cover where I think it would rub a hole pretty quick.

My truck has a 6 o powerstroke. I noticed some coolant loss, which I've been monitoring since I had the truck studded 2 years ago. Today I was looking around trying to find a cause of the coolant loss and I noticed some crusty orange residue on a hose that runs under the coolant reservoir. The hose seems to go behind the valve covers along the firewall to the passenger side through a steel line, and then go in a loop back to itself?
I'm guessing it's for the heater core, but I didn't see where it actually goes into the heater core, or anything else for that matter. It is a molded hose that has one of those crimped transitions into the steel line, so I'm not sure if patching it is an option or if I should look at replacing the whole piece. I'm guessing it's going to be expensive. From the fact that it never failed before, I'm thinking it wasn't originally routed with it touching the valve cover and was just something that happened after having the body off during the stud install.

I had it checked out at the dealer and they called it a "weep" so they went on to tell me that VW probably wont approve warranty work for it. I pushed for them to take pictures and send it in anyway.
Now assuming they won't do it, I have been looking for a DIY or a technical order on the job but I can't find anything.

My 2001 escape recently decided to act up, it was running rough for a little while and then it died and would only run intermittently after that. I found the #3 coil was bad and the egr valve was broken. I replaced those and now when it decides to run it runs smooth but when you give it has it bogs down and dies and doesn't want to run again for a while. I also put on a new fuel filter and the fuel pump sounds like its running good. I know I'm missing something here but I can't seem to figure it out. Also there are no DTC's at all. I really need this car to be back on the road again.

Just found valve cover of my Tiguan is leaking out oil this morning. Will go to dealer tmr for gasket replacement. My car is just over 50k miles. What happened to VW's car quality control???

Haven't had the engine cover off for about 25k now (cleaned it up under there last time I changed plugs.) Took it off today and noticed it's a little oily on all four sides around the valve cover.
Pretty sure I can account for the oil that's near the filler cap... I don't recall spilling enough that would completely go around the entire valve cover though...
But how did it end up so high on top of the valve cover on the corners? It's even a little wet looking on the back if you look hard enough..
I only have 4600 miles left of the 10/100 warranty so I'm glad I caught this and hope the dealer can do something about it... or are they going to tell me this a "normal" amount of seepage? I haven't owned a vehicle with plastic valve covers before so I don't quite know what to expect.

I have a 2009 Escape, 2.5l engine and manual 5 speed transmission, 205,000 miles. It has has an intermittent miss that has been getting gradually worse over the past 3 months or so. I've been seriously futzing with it for the past 2 months, so far no luck. Definitely worse when it's cold. Not noticeable at all in gears 1-3 (even when cold), noticeable in 4th, mostly between ~2000-2500 RPM, and pretty bad when cold in 5th in the same RPM range, still noticeable when warm. No service engine light until today (#1 misfire).
If I let the vehicle idle for 10 minutes or so, the miss is much less noticeable. Replaced the plugs, absolutely no difference. Bought one COP and cycled through all cylinders, no difference. Finally broke down and took it to the Ford dealership where I bought it new and had them do a power balance test, which isolated it to cylinder #1. Swapped the #1 and #2 injectors and took it back to Ford, still showing cylinder #1. Did a compression test, #1 and #2 both around 165lbs, #3 and #4 both around 185lbs.
I'm a electrical engineer, so I spent some quality time with an oscilloscope to compare the drive waveforms of the #1 and #2 cylinder COP and injector...both COP and injector drive waveforms look identical when comparing to #2 cyl. Tried heating the PCM, made no difference (engine was cold, PCM was hot).
So it finally DID throw a code today, cylinder 1 misfire. I'm thinking I can almost hear a miss at idle now. And listening to the valvetrain at idle, there is unmistakably more valve noise coming from the #1 intake area than the other cylinders, but not terrible.

I have a 2002 Ford Escape, 6cyl FWD... 110,000 miles.
About a month ago I started seeing a misfire, which of course usually is a COP issue. I should buy stock in whoever makes those. Anyway, the code according to parts store monkey was cylinder 2 misfire, so I replaced the COP. That made no difference. I also replaced the upper intake gaskets and the PCV valve while I was in there.
So I started monitoring when it would happen, and of course got the actual code rather than taking the word of the monkey at the parts store. The code is P0352 Primary / Secondary circuit malfunction.
So after some research I find it could be the harness, it could be the PCM. The question I have is this misfire seems to only be when the motor is started after it's hot. What I mean is I can drive to work 10 miles, no problem. I can drive to Orlando 100 miles away - no problem as long as I don't stop on the way. The only time the misfire happens is when I start the motor when it's hot. So if I drive 10 miles to the store, then drive home before the motor cools completely I'll be coming home on 5 cylinders. If I wait 2 hours between stop and start I never have a misfire.
Does that jive with a true electrical problem? I'm no expert, but I don't understand why driving for 100 miles is fine, but 10 miles, stop start and 10 more is an electrical problem.
