Please please help me! Will i break my car with a blowing downpipe?
Hey, sorry for the long post but i needed to get all the info up! I have just changed the head gasket for the first time on my audi S3 (225bhp KO4) I got everything sorted and back together and when i started it, it was blowing Because of the position, i cant see very well but, whilst trying to eliminate what it is, im thinking; I put the exhaust manifold on yesterday with the head on a bench (was sent away and dismantled for re build / skim etc. I used a brand new gasket and torqued it all down no problem, im sure it cant be blowing there..... Then when fitting, i put the mani-turbo gasket in place and torqued down the bolts after i torqued the head bolts. I put the gasket in by itself, please dont tell me i was meant to use exhaust paste? If i wasnt, then the only thing i can think of is during jacking etc of the engine to change the cam belt, i have maybe broken a weld or the gasket seal in the downpipe from the turbo??? Thats all i can think of as the other 2 gaskets were new and torqued Anyway, i drove the car up the road and put my foot down, whin it came on boost, there was a screaming sound coming from the engine bay, not turbo whine but like a butch girl screaming in the distance lol Would this suggest that it was leaking after the turbo, the turbo to dp gasket??? Thanks for any info, Cheers :icon_thumright:
