hey warren,

have you tried doing a compression test on the motor you have in there now, there not to expensive
to buy a compression tester and could save you spending on things you dont need. plus its a handy tool to have
especially when dealing with old and second hand motors.

just a thought
Matty

Yeah I have a hand held one - had problems getting it to seal properly on a couple of cylinders, but from memory it was around 140 psi on most of em - might try and do it again.

The thing is its an old unkown engine, I bought a diff and front end and got the motor with it, I've spent quite a bit of time trying to get it running properly were if I had a motor of known condition it could be running by now.

Mezzmo's should be great, straight swap with a known engine, then I can rebuild the other one in my lessure - I get the feeling that the old motor may have burnt valves.

I used to be vague..................Now I'm not so sure

Ah, Rogue, cannot find any "Technical Documents" on site....  ???
The post you did for the brake conversion has a copy of the specified machining required for disk brake conversion but you can't read any of the specs! Can you rescan it so the numbers are legible? Ta.

Also I'm getting a bloody irritating "flutter" in the engine when under load which cleans up when it gets up to 2750 revs. It will also rock and shudder at idle but after 2 minutes settles down to clean.
Have been running it on gas forever, but the engine was (5years ago) recoed with hardened valve seats.
I've checked all the vacuum hoses, replaced brake booster, recoed carby, replaced manifold gasket, compression is equal across all cylinders, plugs fine, electronic dizzy shaft fine, at my wits end!!!

A friend mentioned that holden uses cheap neoprene timing gears that finally give up.
Anyone had this before? Absolutely STUMPED!!

AHA!!! Correct! Sorry but it was a dig at Shane our site admin as I've been after this for a while but he seems to be having issues with the downloading side of it.

Shane, can't you set them up like the flyers on the front page?

Rothu, if you pm me your email address I'll send it to you. How's that?
