Bad noise from turbo

[Fred Munro]

You don't give the year/model of your car, but if it is a Type 44, the sound
is likely from a cracked exhaust manifold. If it is an '86-'88 Type 44, it
could be a cracked exhaust pipe downstream of the turbo near the oxygen
sensor. There is a weld in this area that can fail .

> Hello everyone,
> I'm getting kind of scared. About a week ago a bad noise started. I
thought it was lifter tick, but it got louder with more throttle and quieter
with less. Today I got to poking around and it's comming from the turbo. It
is a whistling-tick-bang sort of. I can't really describe it. It seems to
get quiet once the engine is warmed up. The turbo shaft is still tight and
the fan spins better than it did when I put it on. Could a gasket maybe be
not sealing right? Maybe I have some bolts loose? I am getting tempted to
just take it off and put back the normal exh. manifold for a wile but I
don't wanna give up that easily. I am also getting tempted to ditch my
intercooler and put water injection in instead to free up some room and let
me put the front end back in.
