Golf IV / Jetta IV :: Oil From Valve Cover Leak In Pistons
Jan 6, 2016
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.

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 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?

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 ?

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.

02 Jetta 2.0L that I changed the thermostat. o-ring, and cover on when I first got the car about a year and a half ago.
I see dry g12 coming out from behind the cover and my coolant bulb had dipped quite a bit in recent weeks requiring a refill. What is most likely the problem here in such a short period of time? I've only put like 10k miles on the car in that period. O-ring couldn't have seated wrong because wouldn't the problem have been apparent immediately back when I did the job? Maybe I need to re-torque the cover? Cracked cover?

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?

I have a 07 Sonata and having recurring valve cover leak. First time it happened it leaked onto my alternator and had to get car towed and whole bit. About a year later they discovered it again during routine oil change and had it fixed again. Yesterday during a routine oil change, they discovered a leak again!! I know this is an established problem but how many times can the same problem occur?? I'm passed the warranty (103K).

I have a 2009 Santa Fe Limited with 82000 miles. I have replaced four (4) batteries since it was purchased, new, in March, 2010. I have repeatedly taken it to the Hyundai dealerships in Las Vegas, Nevada and Centennial, Colorado, for an oil leak on the valve cover over the alternator. At no time has the service technicians at the dealerships ever told me there was problem. Last Thursday, the latest new battery, installed that same day, failed. I had my independent garage technician assess the multiple battery failures, with the associated battery display light illumination, related to the location of the continual oil leak. He stated that the cause of the battery failures was from the oil damaging the alternator. I contacted Hyundai Customer Service, today, and was told that there have no reported problems from oil leakage onto the alternator, with subsequent damage to it, and/or the battery.

I had a very slow oil leak that dripped onto the garage floor and i brought it into the dealership. They said it was a leaking left valve cover gasket; I searched and came up with nothing? The engine has just over 30K miles on it.

Well I popped the hood to clean my air filter and noticed that the top of the engine looked to sprayed with oil mainly on/around the front of the valve cover. I haven't really "investigated" to see where its coming from. Where it may be coming from!! It has 32,XXX miles and auto.

I have the 3.1 V6 in my 2001 Pontiac Grand Prix and today it started spewing oil out of what looks like an electrical plug in the front, toward the bottom just under the valve cover, dead center. What is this plug?

1999 Volvo V70 XC. The car is a 5 cylinder turbo charged w/automatic transmission. I removed the plastic panels from the top of the valve cover to discover oil puddled on top of the valve cover. Not sure if it is the fill cap leaking or something more serious. I noticed a rubber tube that I assume is part of the PCV system could this be the source? Also, the car uses oil between oil changes. The manual says to use 5W30 weight oil, but most of the European cars I've owned use 20W50 due to the high compression and torque. I'm wondering if 20W50 might reduce oil burning.

So, when I bought my truck, it leaked oil.....bad. It goes through around 2-3 quarts a week. I needed a vehicle, this one was cheap, so...I run it. Every other day, I put half a tank of gas and a couple quarts of oil in it. It leaks on the passenger side, right above the starter. I figured it was the valve cover gasket, and planned on changing it today. I saw a post about the "typical" head gasket oil leak, which sound suspiciously like what mine is doing. I have no oil in the coolant,or vice-versa.....

Looking for some insight into the state of the motor in a 2002 XD. Short story is that it appears to be leaking oil from the valve cover gasket (common, I know) and sometimes winds up running extremely low on oil before it gets changed. When draining the minimal oil in these conditions, non insignificant amounts of water can be found along with the drained oil.
Car is at 155k miles, has exhibited this behavior for more than a year, and has no noticeable knocking issues, power loss, mpg loss, heating/cooling issues, or any other ill effects other than apparently making a mess in the engine bay, on the ground where it parks, and scaring people when draining the oil.
Logically this is going to not be the case forever.... Thoughts? Prognosis? Treatment?

Today I did a oil change (70k). While under the car I notice a small leak from the back side of the engine. When I got home, I had the chance to remove the engine cover to investigate and clean the engine up a bit.
I found that the bolts in the rear of the valve cover had a little puddle of oil around them. I took a T-30 torque bit and was able to get a least a full turn on the rear bolts and about half turn on the middle ones. Fronts were about a quarter turn. Check your valve cover bolts.
