Apparently the chain failure problem is pretty common with KA24E pintaras, but my setup is not the same as it uses basically L-series double row timing equipment.

Ah that explains it. I knew you were pretty handy at getting things to go. Do you put the sprocket loosening down to "assembly technique" - or something more sinister?
A friend had a KA motor do similar things when the cam drive belt broke on his U12 Pintara. It stopped quietly leaving his partner by the road side. It cost him four exhaust valves plus the new belt and gaskets.

700kms. fortunately it died at the turn off before the hay plain. the cam sprocket fell off the front of the cam and the piston whacked it. The inlet valves on #2 both survived. I did get it running again and drove it into Balranald but it really wouldn't go over 70 clicks. The #1 inlet runner is full of black soot like an exhaust port. Does this seem normal? I imagine the exhaust gas was running back up the runner and out the open inlet valves into the manifold.
As for the fingernail - I washed them before I touched the digital
camera!!

So tell us Zac, 1 Why did the valve hit No1 Piston? 2 In " the olden days" a mere valve hitting a piston and bending

on 3 cyls? How far from Goulburn were you?

OK, it's 7pm. I got the car back at 4:40pm. Tom and I have it apart and got the valve out already.

Proof of why I missed Datnats!
