consuming oil Options

[enderswift]

hey everyone,

I've been having a problem with my celi lately that really has me stumped. This think is losing oil like crazy and i cant figure out where. This is a 99 5s with 92k, and I've always done proper maintenance to it.

I just had to add 2 quarts after a 600 mile trip of pure 80mph highway driving. There are no leaks other than slight weeping from the distributor seal. I get an occasional puff of blue on startup so I'm thinking that it might be the valve seals...but I cant imagine how they would let THAT much oil past.

I did a compression test and got factory numbers across the board so I know its not my rings. The only thing I can think of is that my #4 valve seal got damaged when a spark plug shattered into the cylinder a year ago... But if I was losing so much oil from just one cylinder, wouldn't i see a lot of blue smoke? Is it possible for the catalytic converter to clean up the exhaust so well?

could be all the valve guide seals. and just cause compression is good, dont mean the oil ring is not expanding and keeping oil out. sounds like you need a rebuild soon
