Subject: Re: Lifetime of exhaust manifold?


Does the car backfire on deceleration? Usually if it's leaking it'll pop when you coast downhill. Do you feel hot air blowing around it? Maybe it's the exhaust flange gasket IF you feel hot air coming out there. That's easy to fix. Rusty LOOKING = OK. Even small surface cracks in the manifold that look like little lines are ok & typical. Maybe it's the muffler or pipes. They will "roar" when ya hit a certain rpm. Just be glad ya don't have a 1978 BMW 320i! The "Thermal Reactor" (ie: exh. manifold) on that hunk of junk gets warped & a replacement unit is $2500 new. And most of the used ones are so warped from the excessive heat that you can't machine 'em down. - BL Terho Kohonen wrote: > Hello! > > The engine noise in my 9000i '89 over 3000 rpm is loud compared e.g. > with Audi 100 '89 and 9000 2.0t '97.
