    The voice of reason eh markjay. I guess that makes the most sense. I think as i get older i lose confidence in my ability but the head change isn't that tougher job is it? Move crank to TDC on cylinder 1 with cam lobes on exhaust and inlet pointing up on cylinder 1 remove power steering pump...

    Would you replace them just to run a compression test? I'm not wanting to spend all the money and time on the new sprocketcs, chain, tensioner etc if the cylinders and valves are knackered as i will probably just scrap the car. I was hoping to part-x the car for a brand new one from a dealer. If...

As you can see from the images, the inlet cam has moved approximately 3 teeth over. You can see that the cam teeth...

    Markjay, thank you for your response. I plan to take off the rocker cover and turn the engine to TDC and see if the chain has jumped a tooth and the cam markings no longer line up. Once i have established this i can then consider moving the chain/gear back in line and then test compression.

    @DSM10000 - Thanks for responding so quickly. Ouch, that sounds pretty horrendous. Is it possible that it can jump a single tooth and not totally ruin the engine. I would have thought a single tooth out would mean the piston and valves smashing together and total carnage. Thx
