I agree most 16v, even many 24v, engines can be done without the tools. The GM V6 is not one of those.

Many mechanics think you can do without. In every single case, they are wrong, which is obvious to see when we do these cambelt meets, and find so many that are out. The mobile mechanics here - DLK, EP, JV6 etc - will all confirm that the numbers they see that are out (because a previous mechanic thought it was possible to change without the kit) is very significant.

Quite apart from the fact that you won't get the timing accurate without the locking tools, it must make the job 10 times more difficult with the cams moving around. (don't tell me you locked them with a couple of mole grips.)

All for the sake of a 50 quid kit (only half the cost of the cam belt and tensioners, remember).

with me caly they moved a tiny bit.so lined em up n locked em with 2 stumpy screwdrivers.in all the ones ive done over the years ive never had a prob yet.touch wood.the worst 1 ive ever done was a gsi vectra cos theres no room  the engines so tight on the inner wing.paul

True. There is a lot better access to the cam belt when the correct wheels are driven.

I find the Calibras the worst.

But, you will be amazed how far out the timing is by eye as the crank reference is not great and the two banks are timed differently so the pots dont share the load so well.

The biggest issue is that the iming affects the static tension setting quite a bit and this is where the risk is (on top of the engine not performing to its best).

i did a 3.0l omega a couple of mths ago that had a new belt fitted at a vx dealer and was running like a nail.striped it down and was 2 teeth out.and they said it was done right.hes never had a prob with it since in over 15000 miles.paul
