hello guys i have a 1982 chevy c10 with a 350 engine. brodix ik180 heads. with acdelco spark plugs and cylinders 23468 have oil coming out around the spark plugs. the heads have 800 miles on them. i took a compression test and i got 185 on all cylinders give or take 1 psi. the truck runs good plenty of power. no misses or smoking from the tailpipes. no weird noises from the motor. any help is appreciated i worried my new heads have issues because the iron heads that was on my motor did not do this. i also hooked a vaccum gauge to it and got 18.5 inches of mercury which is normal for the cam i have according to comp cams.
clear ideally color pictures of the spark plugs ,in the heads and out after they are removed,
then labled as to source cylinder number,
and some idea of how much oil your talking about and how and why you noticed the oil,
would very useful.
I have to assume, your plugs are not oil fouled as you stated no oil smoke, missing etc.
are you sure your not dealing with a valve cover gasket or valve cover breather related oil leak?
the likely routes for oil to enter the combustion chamber are past the rings,
through the valve guides or through a leaking intake gasket.
but all would generally result in oil smoke from the exhaust,
you state everything runs well and no oil smoke,
so it seems an outside the combustion chamber ,oil source is more likely.
Id sure test, and look for the oil source,
I'd spray the area below the valve cover and around the spark plugs with brake cleaner,
to remove all trace of oil and run the engine ,
look for a valve cover gasket or breather leak as an oil source.
