10.2mm from memory, its at this lift that the curtain area is equal to the port area so optimum.

Did the engine over speed when the clutch let go as that's classic timing jumped and bent valve symptoms?

Thanks, thatís actually a good diagnosis. Yes the engine had overrevved, but itís still seemed ok, until I parked up. The aftermarket ecu has a limit of 6500 but Iím sure was going higher. So if it jumped a tooth on the crank, that would throw things out a lot. And explain why every cylinder is b*ggered.

Might be worth bunging a decent pair of heads back on it and reinstalling it, by the sound of things.

Plastic Welsh hatchbacks are awesome.
I would like to know what will happen this year, but I don't have 20 20 vision.

Hi, engine man has checked the cam belt and removed the heads. Yes the belt had jumped on the crank, bending all the inlet valves. Pistons are good. He's happy to fit new valves & gaskets. Do I need new head bolts with these engines Y32SE. He's already finished for the day and I'm hoping to buy the stuff online over the weekend.

cheers

For the little they cost, not using new head bolts would be a false economy :y
