burning an unheard of amount of oil

[a_thomasmr23]

the car is a 1990 325i

bought it and broke a timing belt in 9 days

had the head cleaned and leveled use all new gaskets and valve stem seals. About 1 month later I notice some blue smoke when wide open. It got really bad 2 weeks later where during a 50 mile drive I burned a quart of oil. There is oil on all of the plugs except #6. #2 and #5 are the worst and will foul to no spark condition in about 10 mins.

What could be the problem here? I'm think PCV but it kinda looked ok not to much oil in the TB. Or massive ring failure from when the head was off? I mean this is a lot of oil

The first thing to do would be to run compression and leak down tests to assess the condition of the rings. If those numbers are reasonable, a problem with the head becomes the likely cause.

I agree with jlevie. Are you sure this problem wasn't present before the timing belt job? Sounds like piston rings if this is happening at WOT. Loose valve guides or bad valve seals usually cause smoke at start-up and you say the valve seals were replaced.

oh right did that forgot to post them compression was about 145 +/- 5 in all cylinders, the leak down was some what hard to do as I have a shitty compressor but I could here air in the dipstick tube but couldn't get and usable numbers from it

[a_thomasmr23]

I don't know if was there or not before the head job like i said i only got to drive it 9 days before it became a project car :(

jlevie: what would the likely head problem be?

[jlevie]

The compression numbers are a bit on the low side, but not terribly so. We really need the leak down numbers. If your equipment isn't up to the task, have that done by a shop.

The head problem could be worn guides or gasket leaks, or even a problem with the seals. But I'm betting or worn rings at this point.
