I started a thread in April regarding my son's scooby blowing out blue smoke.
Most replied that it sounded like the turbo.
After a lot of idiot mechanics.
We took it to a specialist. It was discovered that it has cracked two pistons. So a full re-built was started. New forged pistons to be fitted after a 1mm skim on heads. All bearing replaced new steel connecting rods fitted.
This was an WRX import, and the company doing the work were puzzled that the engine had a RA inclosed block. It will be returned hopefully next week, and now for a run-in on mineral oil for 1000 miles. Just goes to show that not all on the forum is that genned upon subaru's.
Lots of Monies spent but will end up with a engie that will now boost to 1.5 bar, and a top speed of 143MPH whoopee
