how did his tails turn out? how long were you guys at my house after?
also is it normal to have a high pitch sound coming from the engine after seafoaming [only when engine is cold?] i never had it before seafoaming.
any ways, the video is a good 8-9 minutes
what kind of sound is it?
awesome!
That is your air pump. The air pump turns itself off when your engine is fully warm; the purpose of the air pump is to help your catalytic converter live longer.
There are several cases where the air pump's bearings fail and that will cause a nasty high pitch or buzzing sound.
