burning oil and black smoke?

Question

so i've blown my motor twice already. first time i've just replaced the piston and when i blew it the second time, i did the whole works. bored, sleeve,port and polish head. so my problem is ever since when i push on the gas black smoke would come out of the exhaust and its been draining my oil. i would have to put 1 quart every 2 weeks. there's no leaks, i don't see any oil stain anywhere around the motor. also i haven't tuned my car ever since i've rebuilt the motor into a 2.0 liter, before it was a 1.8 liter. so any help would be greatly appreciated.

recheck your timing.

Unfortunately burning oil is not an easy fix. I would check the engine's breather system to make sure that its functioning properly and not pumping oil into the air intake system. That being said its most likely a worn mechnical part inside the engine (i.e worn piston rings, valve seals etc). With the amount of miles on the engine complete rebuild or replacment would be necessary. And that might not be cost effective on an 11 year old car.

If it's using oil you might have broken a ring. What ever it is it's internal and not something that can not be fixed with out tearing it back down. Do a compression check on it and see what that says. It should at least pin point the cylinder that needs attention.

Sounds like your rings never got seated. Did you put the rings in correctly?
