hey guys i have got a tapping niose when it is started i when i run it for about the first 15 mins, i took the exhaust off when i did the head gasket do you think it is that blowing when its cold.
Probably is the exhaust as it will expand and close up any gaps at the headers. Might even be just nut on the studs that has vibrated loose, that happened on my 7R. Has it got the copper seals in place?
