ported the turbo last week and since then there has been a loud whistling noise coming from the engine every time the revs go above 2000rpm. It seems to be coming from the rocker cover, I thought it was the oil breather causing a problem but it isnt. there is a crack in the manifold, could that be causing this?
any help would be greatly appreciated because its doing my nut in!
cheers.
