1985 camaro 305 tpi, i pulled my plugs and all of them are fouled, i figured it would be quite hard presses that all my valves would go bad since the engine was rebuilt in 2002

Bad rings
Bad valve guides
Bad valve seals

but that would affect all of the spark plugs, i would think if it was something to do with valves it would afferct one two but all 8 spark plugs

R u sure it's oil and not fuel ?

Valve stem seals go bad, does it smoke or puff when u start it up?

How does it run once hot and warmed up?

Also our cars are common for leaking intakes as well. Oil entering down the side will go thru all cylinders, but u should seal oil pooling on the intake between ports most of the time.

U gave us no info to go on, so u need to tell us exactly whet u know and see

I see, i have other things going on but the people i talk to say that the oil fouling is a completely differnt issue, and for the other problems i have been following another post but heres all of it hopefully i can get this fixed

-all 8 oil fouled plugs
-burns quite a bit of oil about 1qt every 45 days
-hard start with no preference for hot or cold
-on a bad hard start it will blow out a bit of smoke i see it to be white
-if the engine get started and turn it off and try again it will start right up
-runs perfect when started
-fuel pressure test says all is okay

i have taken it to 3 shops and they all cant seem to figure it out.

i have tried:
-O2 sensor
-fuel filter
-injector cleaner
-tune up
-coolant temperature sensor
-fuel relay
-new ECM

i hope this one gets figured out, cuz i'm in the same boat and been sinking for a while... am getting close to have the time to get in to mine, but my same issue came about after a rebuild, too... uses about 1qt oil every 500 miles. i resealed the intake long ago to no avail, as well, so have pretty much ruled that one out. will be checking the valve guides and seals first, rings if i don't find anything. all 8 of mine are fouling, too.

Run compression and leakdown tests.

and to add to this, why am i smelling 'raw' oil sometimes when the engine is running?

Is your PVC functioning correctly?

as in, the check valve working properly? i'm pretty sure about mine, changed the valve, but at one time i put a breather cap on there and it still sucked down the oil... is there a way to check that system otherwise?
