Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

What do you think? I was going to purchase the crossover tube as I suspect it�s the likely culprit and disassemble to inspect further. it burns oil when running, or at least smells like it. Doesn�t smoke from the exhaust. Doesn�t drip oil.

POST 2Original post

If I were going to all the trouble to replace the crossover tube, I would replace the entire AOS system Also, I would only consider the UAOS. Lot of threads here to learn more about the UAOS.

POST 3Original post

Just replace the whole thing with a UAOS, and you will never regret it or worry about the issue. It is just peace of mind for a few hours' worth of work as well as a few bucks rather than servitude to the existing AOS.

POST 4Original post

I agree with everything said so far, if capable I would drop engine and trans and get a good visual on your leak and easier to do all of the work.

POST 5Original post

People above are smart, replace the hose and put a UAOS in when you're going through the trouble anyway.
