350 chevy engine burning oil

Hi to Everyone, my 350 chevy engine has a 400 turbo transmission,recently
it began to smoke and burn oil, I was told it could be the modulator in the transmission , have replaced the modulator but it still smokes and uses engine oil, checked the crank case vents in the rocker arm covers and their all clear and working properly , engine does not have excessive back pressure in crank case vents . Do not know why it is burning engine oil, can you give me help on this ?
Thanks, Bill

Sounds like time for a re-build.

350 chevy engine burning oil

Thank you all for the come back, the tail pipe is dark but not oily and don't know how many miles are on it. is it possible the fuel pump could be sucking oil from the crank case into the fuel ?

could be a number of things.cheek your plugs for any noticable fouling.a dry or damaged vavle stem seal.i would get a test done on cylinders first,if its a oil ring on one cylinder you can slip the head off without taking off the maniflod and push that piston out.good luck dude

You don't mean without removing the intake manifold do you?? I would think real hard about that one if it was me, the intake is so easy to remove, why fight it?

i have done it this way in the past to save time.depends on what sort of time you wont to put into it.if it was me i would pull both heads to check cylinders and fresh gaskets.but as a quick fix by slipping head out you dont have to mess around with dizzy,kickdown etc
