Strange Yellow Residue on Oil Cap?



Actually i wasn't giving you ****, Guy.

I told you what to do in chat. Did you listen?

Clean your ****ing oil cap, keep an eye out on things (Maybe take a road trip.) for the next few thousand miles and see if it comes back.

If there is enough coolant in the oil to do that to the cap then there is enough in the pan to be noticeable. Pull the dipstick, if it is milky like the cap... you have coolant leaks... if not... it is moisture buildup on the cap. I see it alot in Oklahoma, on regular vehicles that aren't driven much or sit for a while.

If the oil on the dipstick (that would be in the pan) is not milky, then there is no coolant in the oil... right? no risk of knocking... sheesh, stop scaring the poor kid.

Clean it, go for a good long drive, check it again ;)
 
ive had that before. not quite to that extent, but mine was just moisture. to be sure, clean the cap and do an oil change to inspect the oil, then take her for a drive of let it warm up to normal temps....then see if it reapperas.

My 3800 Firebird had that same crap in the oil cap. For 80,000 miles. Every 3000 miles the oil got changed, and the cap was gunked up with nothing at all in the oil.
 
Hi Hippo,

It's definetly coolant could be a blown head gasket, As for sittin causeing the problem, I used to live in NY where it got real cold and mositure was plentuful, I've left cars sit 9 months at time and NEVER had it cause that problem. I say do a compression test on all cylinders and YOU DO IT so you are sure it was done and done properly, low compression I'd say head gasket. See if Bill boost or drunkie back me up on that.

I also rarely drive it more than a mile at a time.
 
It's def not a head gasket they almost never fail unless tampered with before. If you fluid levels are not going down at all and your oil looks fine I'd just take it on a longer trip after cleaning out the oil cap and see if it returns.

Head gaskets DO fail overheating, running with coolant way too low, using and INTERNAL engine cleaner such as sea foam on an older engine (especially if it has not been rountinely maintained) can all cause them to fail, I have seen blown gaskets on a 1972 duster, 1963 Plymouth Belevedere, 2001 Chevy Venture Van and a 1972 Mach I mustang (with the supposedly indestructible 351 Cleveland engine). Been working on cars since 1970, and I did say to run a compression test first to be sure

Have you ever seen hg go bad on a 3800? If it was overheated it's possible but i doubt it was
 
How long has it been since someone cleaned that cap off? That residue can be normal, it depends on how long it took to get there. It could be left on the cap from where the intake manifold gasket leaked before. If the oil on the stick looks good and you aren't losing coolant, do what someone else above suggested. Clean the cap off good and then drive your car.
 


if the oil itself looks good, then i beleive (for what ever thats worth) that it is not coolant. Did you change the oil yet Hippo?
 
OMG 2 pages in and you have nothing but what somebody and others have told you.

You, Hippo, Joe, GO yourself and look at that engine. You be a big boy and you pop that hood! Look at the valve cover, then look between the head and the intake (like blue said) and see if it's a piece of plastic there or a piece of metal. THEN you will know for yourself if you have the chance of a coolant leak. And we shall take it from there.

Go on. Take the first step.

Waterfalls aside, it's probably just moisture buildup man. Clean out the cap, drive it and check it every so often.
