High Pitched Squeal On RB20 GTST

[cattivo_69]

Hey guyz

i had the high pitch sound on my rb20, sound like u were deflating a balloon.

Ended up being snapped stud bolts, 3 were snapped, and the rest basically just fell apart when i took them out, this was only last week

12x stud bolts- $36 (from autobarn, same as the VL)

go to a nut and bolt place and buy sum brass nuts and sum washers

if ur replacing exhaust manifold gasket too, $95 from nissan, they have sum in stock

also found that the four bolts holding the turbo to the manifold were also loose.

One had fallen off and was sitting just underneath the manifold the others were just about to fall off.

My old man bough sum easy out stud extractors, god bless those things.. makes things so much easier. IF u can borrow a right angle air compressor drill this will also help heaps too.

We did it ourselves, just takes time and patience coz its hard getting ur hands in there, and becoz theres so much heat generated in that area, sum of the bolts when u remove them just crumble.

So be prepared to swear allot.

Hope this helps!!

Cheers Joe.

If u need to kno anything.. give us a holler!!

cattivo_69: You mean, I assume, that some of the manifold-to-head studs had snapped?

Personally I found replacing the studs on my car (I did head -> manifold, and turbo -> dump studs) was really easy. Little bit of penetrene, then tighten two nuts against each other and they came out with hardly any effort. You want to be careful with putting too much pressure on the studs....

IIRC, the exhaust manifolds were only about $60 w/ SAU discount when I bought them: good reason to sign up to the SAU club (if your in NSW anyway).

Edit: You should also replace the locking tabs.
