I have a 82 Scirocco with a droped in 88 GTI 16V 1.8L engine. When i rev my engine and get to 3000rmp's i get like a winey screachin sound coming from around my timing and other belts. Then when i get to around 3500rpm it stops. I think that it may be rubbing up against my belt cover, but not to sure.Any ideas? Please help me its really annoying.
