Does anyone know about back pressure??!!- do i need a new engine? OK, Took my car to get a simple diagnosis due to it smoking. I originally thought the head gasket was blown on the passanger side and the smoke was burnoff from the oil hitting the exhaust. The mecanic told me that the oil pan gasket was blown and needed to be replaced...that's done and i still have smoke-even more. New diagnosis says it's back pressure due (coming out of my dipstick) to the age/were and tear on my engine. The car is a 98' T/A with about 225,000 miles on it. The only remedy I'm getting is to replace the motor! The question I have is what else could be done. My PCV is clean and so is the throttle; why is the pressure not goming out the exhaust. I am on the market for a ls1 motor if anyone has any suggestions, (I'm in Mo. City) but I want to build this one the way I want it, any suggestions would be great!!!

Yeah - check your compression. This will tell you if one or more cylinders have bad rings and is giving you the blow by. Your probably going to have to pull it and atleast re-ring it. But I would just rebuild the whole thing while you are there

Your problem is blow bye not back preasure. Do a leak down test to find out how bad it is and go from there. If it is bad enough you will have to rebuild or replace the motor. The cheap way out would be pull the motor inspect the pistons and cylinders. If they are good you can hone the cylinders and put new rings in.
