1994 Subaru rs legacy twin turbo. my Subaru is blowing a lot of blue smoke and has all of oil all of a sudden and not boosting . the turbo is making a metal on metal rubbing sound??? what could it be??? thanks.
Sounds like the oil feed lines aren’t feeding your turbos. These are usually held on with “banjo” bolts on top of the turbo. Look for oil leaks anywhere on the engine and make sure that the feed lines are clear.(usuallyy pretty easy and cheap to just replace the lines). Also make sure that you have enough oil in the engine and that your oil pump is working.
