Need some help figuring out my oil consumption.
I've got a 2003 Legacy L 5MT with 165,000 miles that's using a lot of oil but I can't figure out where its going. Its "burning" through a quart every 750 miles I think, possibly more.
I have no visible leaks, no signs of oil in my coolant or coolant in my oil, no smoke while running, and my spark plugs don't show signs of excessive oil burning. I had every gasket from the heads out changed about 10,000 miles ago along with a timing belt job.
I've been asking around other forums about this and some suggested the rear main seal or oil separator plate. This possibly makes sense as my clutch has begun to shudder in 1st just recently and I believe the clutch only has about 40,000 miles on it. Again though, no signs of a leak around the tranny.
I'll take any and all suggestions! I just want to get this figured out!
