oil burning ?????

[the on going reality of shopower]

Ok this is the story:

Well I was at dyno day with SHOPOWER in ONTARIO my father drove my 91 PLUS. I have been using oil alot and today my dad drove away from parking all afternoon and all this grey smoke poured out from the exhaust been doing it for awhile) I always thought it was blue but the SHOPOWER members think it was grey. You have any suggestions on what the heck it is.

I was told to decarbon the engine and check and see if the hose from the valve cover to TB is plugged. and also clean up the intake manifold. Does this sound like something to cause it??

Any input would be greatly appreaciated.

ALSO my 93 ATX dyno'd 180.7 HP and 190.7 TORQUE

blue is burning oil, white is burning antifreeze, black is burning fuel.

sounds like valve stem seals or rings. but you would have to do proper inspection to rule out the rings. remove the crossover tube. if there is oil puddled in the intake, that is oil blow-by and rings are suspect. PCV system and spark plugs need to be checked to confirm bad rings.

i recommend using RxP from Auto-Zone. it comes in a 5 oz. orange bottle with a yellow label. one bottle treats 25 gallons and costs about $7. its a decarbonizer and it worked wonders for me. but using a decarbonizer wont rid you of blue or white smoke. the black smoke is present on many SHOs i have seen and is simply excess fuel not being burnt in higher RPMs. i can very easily get my car to puff black smoke.

well the results are in this morning I started it up and rev it a bit and little to no smoke. But i will inspec the intake tanks. and also would a compression test tell if the rings are toast??
