What is "a lot"?

Error could be just that, compression bypass into engine crank chamber.

Do compression test to check for possible piston ring problem.

nearly a qt per week. is it possible that the o2 sensor and egr could cause that to happen, burn oil that is. i changed the o2 sensor tonight.so one problem down. the scan i took prior said bad sensor and egr malfunction, i figure one went with the other. wil check compression as soon as i can .. thanks

If u say one qt per week, I read its leaking...?
One qt per 1000miles is not bad [but maxima it should be none]

Oil burn has two causes [burn, not leak]:

1. Piston rings do not wipe oil down as they travel, get combusted. Major overhaul. Check by compression tst.

2. Valve seals. Can be changed while engine on using compressed air into cylinder under operation [keeps valves from falling]. 2hours? plus parts 50$?

thanks, i'll check it out.

i'm told my problem could be a clogged pcv valve causing the oil burning. worth a try to change it , but i can't seem to find it. can anyone tell me were it is located. the thing is small i'm sure i looked right at it already.

OOPS. Corrction: Btw u have to take cams off and that means belt off (+4hours)

Ref: 2. Valve seals. Can be changed while engine on using compressed air into cylinder under operation [keeps valves from falling]. 2hours? plus parts 50$?

"nearly a qt per week" ...onlY PCV???

[mhgjr]

so far everything is fine i'll let you know after a couple of weeks.

[mhgjr]

well it's ben a couple of weeks and the oil burning has stopped. so check that pcv valve or just replace it. it cost less than 2 qts of oil.

Good to know, thanks. Chances are, lifetime goes without any pcv problem.
