Just got a 99' Legacy b4 turbo... loving it, drives nice. Just had full service upon purchase. I've been told it could be the valve taps, but there is a slight clicking noise coming from the engine. It is most intense in the warm-up phase. Is this normal? and does it need another service? Also, the turbo's have a loud-ish whine sometimes

The turbo whine noise is normal, espesially if it has an aftermarket intake and/or exhaust. The clicking noise could be the valve lash is a little loose, I have also seen the timing belt adjusters make a knocking noise when cold too. Make sure it is not coming from the front of the engine, if so I would have your tensioner checked out. If it is coming from your valves you will have to pull the engine to remedy it. Well you don't HAVE to pull the engine but it sure makes it a lot easier. You can check your valve lash with the engine still in the car pretty easy and see if it is whithin specs. Is that something you are going to do your self??? If so I can walk you through the process if you like.

Thanks rutech, this sounds like it could be something worth taking it to the subaru specialists, id never forgive myself if i screwed it up, even though you sound pretty onto it. thanks for the advice

Yeah sometimes it is best to have someone else do it for sure. Good luck and let me know what you find.
