Should I be worried?

[markeemsz]

I checked my oil today and noticed I was a quart low. I just filled the oil 2 weeks ago . I was low then too. I have put a few hundred miles on my car in the 2 weeks before I checked it again today. do u guys think I have an engine problem . The car is a 1993 Chevy Cavalier 3.1

probably the distributor o-ring, or the rear main seal.

[markeemsz]

Yeah I changed the o ring last year

I wouldn't be surprised if it's leaking again, unless you took extra measures to seal it up better.

The O ring is usually pretty reliable if it was installed right (like not torn or damaged) and is left un disturbed. Try and find out if you are consuming the oil check for excessive carbon on the plugs and in the intake. While the car is running, especially off idle acceleration, check for blue smoke.

I ran the car for about 15 minutes with cardboard underneath the car. I saw a spot of oil . Just to be on the safe side Im gonna tighten my drain plug . The oil looks like its leaking around the cover that covers the flywheel. Its definitely motor oil and I dont think its coming from the drain plug but Ill check in a few days . Any suggestions on what it could be ?

If it is barely leaking external, I would check the PCV system. It likes to suck up lots of oil and have the engine burn it when the spring inside it gets to hell.

I just replaced the pcv hose and pcv valve last year (the old parts were the originals from the factory . ) Do u think those parts may have gone bad already ?

[SappySE107]

Did you get the GM PC valve or something from the parts store? I dunno how much it matters but I have heard that the GM spring rates are meant for the engine and the parts store stuff is generic. On a modded engine I dunno how the GM PCV could work at its best anyway.

I am using K&N filters now and my oil consumption stopped Also, if you have the tube from the front cover to the intake, use a K&N on the front cover instead. There is now PCV there but mine was sucking oil pretty bad there.

[markeemsz]

I used GM pcv valve and valve hose. I still have the stock tube from the cover to the air intake .

Yeah I changed the o ring last year

Ok maybe I had a little help

[soup1279]

a little eh? lmao

anyways i would check the drain plug, just because the oil is on the ground in that area doesnt mean that is the problem.

Pull the pcv valve and check it to make sure its not clogged up. While your under the car tightening the plug take a rag and clean off the the oil pan as best you can. drive the car normal and check the seals around pan for leaks.

Your not blowing any smoke right?

[markeemsz]

Ok I will tighten the drain plug tommorow and check the pcv valve. I just cleaned the undercarriage so that wont be a problem .

Oh yeah and theres no blue smoke or white smoke when I started it in the parking lot

[soup1279]

what about under load? when you hit the gas under normal driving conditions no smoke?
