Golf IV / Jetta IV :: Engine Won't Start After Replacing Valve Cover Gasket
Feb 7, 2016
My mk4 sat for a while and upon starting up was misfiring. I checked for pvc leaks and didn't see anything but went ahead and cleaned my maf sensor and decided to pull my coils. Cylinder 1 had oil on the tip and around the spark plug which to me spelled out a bad valve cover gasket. I got all the parts to do the inner and outer gaskets and replace the coil and spark plug, however we got a snowstorm and my luck a rabbit got in and ate the wiring on one of my fuel injector connectors.
So went ahead and put on the new gasket, replaced the coil and plug and bought a new Fuel Injector Connector and spliced in onto the Injector "Pigtail'. I double checked everything was reattached properly and let the gasket sealant dry for 24 hours. I went to start it tonight and after trying to turnover it completely cuts out, wont even start up. I'm extremely frustrated at this point and am thinking the rabbit must have gotten to something else unless I did something wrong in the process of repairing.

I did a valve cover gasket replacement. Changed all spark plugs and coilpacks. The car is still misfiring. I also just did the timing belt and water pump. Why it's still misfiring?? I'm new to this whole forum thing so bear with me lol. I'm wondering if it would be my cat, fuel pump, fuel filter. Or could it be a sensor?

I'm thinking of purchasing a 2001 GLX VR6 Jetta with lots of deferred maintenance (shocks/struts, brakes, exhaust). Most worryingly, the valve cover gasket is leaking oil. The price is pretty low, but is such a beast worthwhile at any price or is it better parted out? And the interior is about as beat up as the mechanical--screeching passenger window motor, broken glove compartment ... Is this thing worth being brought back to life?

Changing the valve cover gasket on the 4 cylinder 2.4l. I was going to change mine's. Didn't know if there are any special tips like sealant to be used, loosening bolt sequence or tightening sequence, torque values.

I'm replacing the valve cover gasket on my 94 Honda Accord. I've heard all sorts of crazy opinions on what needs to be done while installing the gasket such as using various sealants or lubricants. Should anything be put on the gasket or should I just drop it in and screw the valve cover back on?
I'm also replacing the spark plugs while I'm at it. Is there anything else I should do while I'm in there?

I'm looking at replacing the valve cover gaskets on my 02 f-250, it's a 7.3L.
Looking at them on line there are many different brands. What have you used on your 7.3L, and which has worked the best for you?

I've got a coolant leak here (I wiped away some of it before taking the picture):
Close up
This is the only place I can find coolant leaking and it's running down all the way to the water pump:
When I wiped away from just below the valve cover gasket it flaked right off and it doesn't appear there is any oil mixed in. I changed the oil today and it didn't appear to have any coolant mixed in either.
The coolant doesn't appear to have any oil in it's nice and pink as it should be. I started the car from a cold start and sat and watched the area waiting for it to leak but nothing ever came out, of course.
I know there shouldn't be coolant leaking from this area anyways but I don't know how else to explain the trail pictured. I definitely have a small leak somewhere as I've found coolant on the floor of the garage before.
Do I just replace the valve cover gasket and move on or is there something else I should be concerned with here?

I just noticed what appeared to be an oil leak around the valve cover gasket, which the VW dealer has determined to be a defective cam sensor. Apparently the VW parts distribution center in Wisconsin has 530 of these in stock, so it may be a common failure. This is on a 2010 GTI with 28,xxx miles. Thought the community would like to know.

I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.
After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.
Other things which may serve as clues:
Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)
When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.
Car has 107K manual shift.

I drive a 2003 24V VR6 GLI
I recently did a valve cover repair to stop the dreaded misfire problem. Well, I'm still waiting on a few things but during the spark plug change obviously some of the oil from where the valve cover leaked previously fell into the pistons because I couldn't really clean it all out efficiently. This seems like it would cause a lot of problems? Do you think I should throw old spark plugs in there and let all the oil burn up before finally replacing them? I really don't want to foul up my brand new NGK's.
Also, I pulled p0300, p0305, p0306, so I am guessing oil in the spark plug/coil pack connection may cause some of the misfires, but do you think two of my coil packs are bad still? My plan was to move them around to see what happens after I get the new parts and am actually running again.

when replacing valve cover gasket, using the cork based one. Do you use any gasket sealant or any kind of silicone or just put it in by its self.

I know this isn't the usual ticking of the injectors and I believe it's to fast to be a lifter tapping. I believe it's the camshaft chain hitting against the valve cover. I took the valve cover off and the chain is still tensioned tightly so it makes me wonder what this could be..

In order to replace the valve cover do the spark plugs have to be taken off ?

so I have a 2azfe engine
So there's an oil leak coming from the valve cover gasket (just purchased vehicle dirt cheap with 220k)
found this
Notice all the oil sitting on top of the exhaust mani gasket
In the left(lower) part of the picture it appears to be scraped.
the gasket appears to be newer, I did NOT use a screw driver to remove the valve cover, which is what this appears to have been done..
Can this be sanded down then filled with jb weld, and then regasketed?

So I'll be taking on a project to replace the valve cover gasket on my 2002 Camry V6. There's a bit of leakage through the gasket. And while I'm at it, I'll replace the spark plugs as well. I'm looking for a write up on this project. did a lot of searching but couldn't find anything.

I have a 99 passat 2.8 v6, that closing on 200k miles, and its a car i'd really like to keep, lately i've had a few leaks coming from valve cover gasket, which i replaced, and now from the front drivers cam, and the rear passenger cam, the smell is terrible and the smoke is worse, i clean out the pcv but its still happening, i talked to a mechanic he says with that many miles i should just do the timing belt and get the seals done.

How difficult is it to replace the valve cover gasket on a 2001 Santa Fe with a 2.7? Can I just do the 'front' valve cover? Are there any tutorials with plenty of pictures while doing this?

My son-in-law came by tonight and showed me his ticket from his oil change at the dealer on his '08 Azera, 108k miles. Tech remarked that both valve cover gaskets AND the oil pan gasket were leaking. I've walked through his garage many times when my daughter has the car at work and I've never noticed any oil on the floor. Should have I seen any? I told dealer I would just drive it and monitor the oil level and any other signs of oil leakage. Since he bought the car with 101k miles and a fresh oil change ticket and never checked the level over the next 7k miles I don't think it's leaking bad.
