Valve cover gasket

Can a bad VC gasket cause oil burning?

I never drive my car hard or anything and there is a little oil on my plugs (not the electrode though) so im thinking the VC gasket is leaking oil into the combus. chamber. buring some.

let me know

Your valve cover gasket won't make your car burn oil, it will just leak on the outside of your engine or down around your plug wire and fill the hole where your plugs go. Your piston rings would make your car burn oil and get on your plugs, does your car smoke blue when you first start it or when you drive it? It could also be your valve seals or your pcv valve could also make it smoke. Hope this helps. Nate

I'm hoping its not the rings , but anyway there was blue smoke before but not anymore, its mostly white and lots of it.

I'm not loosing anti-freeze though.

There's no way for the valve cover gasket to leak oil into the combustion chamber.

If you are blowing lots of white smoke you are burning coolant somewhere--either at the turbo, or at the headgasket, most likely.

You need add make, model, trim, year of your car, etc. to your signature if you expect to garner productive advice. Like you see below VVV "96 Eagle Talon Tsi Awd"

[sarcasm] Like I've said before in one of the other 1500 posts about this... [/sarcasm] It is VERY difficult to tell the difference between white smoke and blue smoke, because the blue is so light. And I've blown countless turbo and head gaskets. In all my years, I have never had a HG cause any smoking. Every time it was combustion pressure blowing coolant out of the overflow, or "pushing coolant" to use the lingo. A bad turbo will eventually smoke like a chimney. It will smoke a little for a few K miles, then just go to hell at some point. Also, leaky valve seals never smoked for me, even when burning 1 quart per tank of gas!! These are just my experiences, but pretty extensive, and should cover the majority of cases. Turbo is most likely suspect.

If this is a NT car, the most likly suspect IS the head gasket, because there is no turbo BS on the car And 2G NTs arent exactly known for good HGs in the first couple years anyway. My my personal experience with NT DSMs is little to none

Thanks guys, yea sorry I have a 95 NT, I will consider the head gasket. Could the head gasket lower the compression though?

[kjewer1]

It can. Usually compression wont be zero (thats usually bent valve), but will be around the 100 area, from personal experience and from what I have seen on other's cars.
