Are you sure it was head gasket failure and the water pump hasnt seized?

yes it was definatly the head gasket, the water pump is shaft turns fine but I need to rotate the whole pump to adjust the timing belt tension.

There are three bolts holding the water pump onto the block, all three have to be loosened off a bit to move it.

There is a spot on the casting to put a special tool so that you can adjust the water pump position.

I usually just make my own tool.... it's basicly something like a 40 to 50 mm wrench that is very skinny ( can't remember the dimension off the top of my head )

There is an official GM tool for the process but it's not exactly cheap..... where are you located?

I have a dead 1.5L SOHC (heavily bent rod on one cylinder) that has three decent rods.

So I don't have a problem giving you a rod for free... you would simply have to pay for shipping.

In fact, you should take 2 rods just in case..... I'd leave the pistons on there as well... I have no use for them... then you just swap in your old bearing and away you go.

I want one rod/piston combo for my collection of components ( I have rods and pistons from a whole pile of Opel/Daewoo engines )
