Crazy Cas

[Black4DR]

Pretty certain my CAS is poked. But i want to see if anyone has encountered this problem before...

When Im setting my timing, everything is algood until i start tightening the three bolts up. Everythings mint till the bolts just start to touch the spring washers. Then the timing jumps from 15 degrees to tdc. Its not even a gradual change like what normally happens sometimes. Its like someone flicking a switch!!

And it changes while I drive. at times the cars gutless and pops out the exhaust between gears, other times it goes mint...

The engine is a Rb20det.

Obvious first question, are you using the top cam belt cover or is it left open?

If left open did you pack out the CAS from the bracket, the same distance as the cover?

still has the cover mate, and all of the little metal spacers are still in the rubbers.

Really dont know why it does it..... I can get a new wheel and pick up for a few hundred bucks..
