Oil question
 

How many different ways can you lose oil? Valve covers, main seal, piston rings...anything else? My car is fine when I drive around normal with it, but after a couple of days of gettting on it it will drop just a smidgen. There is no white smoke when getting on it and dont smell any burning oil. The valve covers are spotless, so there isnt anything leaking there. I changed the oil a week after I got the car(over a month ago) and there was nothing leaking around the oil pan. Since the oil change I have added a quart as of today. The oil is clean. Will a compression check tell me anything? Anything to worry about the heads? Any ideas?? :)

Oil disappearance
 

bobtod:

Most 5.0's use a little oil as a matter of course due mostly to 'looser' oil rings - but not to the point of actually causing blow-by.

I bought my '90 LX new and have used about a quart every 1,600 - 1,800 miles ever since. Still does this after more than 116,000 miles. No smoke, no clogged PCV screen, no problem.

Relax.

How many miles on the motor since it was refreshened? Since you have been through the motor (installing the 10.5:1 pistons) - what type of rings did you use? I would assume that you didn't use the stock ones that Mr 5 0 is referring to. A good set of rings (C&A, Federal Mogul, etc.) on a refreshened motor should not be burning a quart of oil every 1,600 - 1,800 miles.

FWIW, my old 302 'burned' little to no oil whatsoever. I would get about 4.5 quarts out with every change (probably another .25 - .4 was in the head vallies, coating the rockers, etc.
