Burning oil?

My 1995 SC buick riviera is burning oil especially at idle and take off. What kind of simple things can I check before looking at more serious repairs? I was trying to find a manual so I could check the valves but I havent had any luck with finding a manual for this car either.

Sorry to tell you that there is no simple fix for this. If it is burning oil that means the rings are bad. Rebuild or different motor!

Do you think it would be better to have it rebuilt or replaced? I dont know enough to do an entire engine myself and I dont want to get ripped off on an engine that may or may not have actually been rebuilt. I really love this car and I want to do what I can to keep it in top shape.

Well if you really like the car then put a new motor in it. If you can't afford a new one put a good used one in it.

Burning oil on accel. Is a ring problem. Burning oil on idle is a valve seal problem then it burns the residuale on take off. What does it do on deselerate. Does it start burning again. On high vacum on decell. And/or idle it sucks oil in thru a bad vavle stem seal. Good luck

Could that leaky valve seat (or seats) be what has robbed my car of it original power? I may not have to have an engine put in after all. With the right info I could possibly do a valve job myself. Does anyone know where to get info on 95 SC buick riviera? Chiltons and haynes dont make it...

Gm doesnt have the best valve seals in the car industry. If the smoke clears up after a short time it will be the valve guides. If it continues to smoke constantly it will be the rings.

But I would rule out the rings with todays engine technologies. My truck was driven hard every day it started, and pulled race cars, tractors, heck anything I could hook up to it and I pulled it out running perfect at 221,000 miles with no bearing wear, almost no cylinder wear. Only thing was egr ports were 80% clogged up from sludge.
