Burning oil

My 88 Pontiac Firebird keeps fouling out the plugs to the point where they are wet with oil. I dont see any smoke from the exhaust, any ideas?

Re: Burning oil

Is it oil or fuel on the plugs?

Re: Burning oil

How many miles? Some pics of the plugs would be nice. How much oil are you consuming in between changes? You could also do a compression check on all of the cylinders. I hope its nothing serious. Are you sure its gas?

Re: Burning oil

Not if you have a catalytic converter. If its real bad you still would but those converters will hide a lot.

Re: Burning oil

Worn rings. As mentioned above: How much oil are you having to replace? I have worn rings also and it does consume oil but not enough to warrant an overhaul at this time. I will tend to see a bit of smoke when it's first started but after it warms up, it is barely noticeable. I probably replace about a quart every couple of months.

Re: Burning oil

Compression check. If good, valve guide seals.
