Squealing 21R (problem found!) Tue, 07 June 2005 05:47 Go to next message
Hi all,

http://www.overclockers.com.au/~mwp/temp/dead-21r. avi
Its 4Mb.

Anyone know what the cause of that noise would be?

As far as i can tell its coming from the top/back of the rocker-cover.
Im guessing its a cam shaft bearing, but i cant check them without removing the head (=pain) Sad

Thanks.

i didnt watch the video but...

possibly just a hose loose/cracked on the inle mainfold/carby somewhere.

i had the same problem with my 18rg, then it came back just recently whan i fount the 4 bolts in the balance tube had worked them selves loose Embarassed

another possibility: alternator fin bent out. that can do it

another possibility: you might have a frog stuck in your alternator Laughing

Gotta love these old engines and cars!
Took me a whole 2.5hrs to remove inlet, exst manifolds, etc and then remove the head Smile

Before:

Half way:

Easy to see one of the cam-shaft bearing caps is well worn, and the nick in the bearing surface on the camshaft.

Now to either get it repaired, or buy a 2nd hand head...
