so i put the head back on my m10, and it cam sprocket isnt really going well easily, when i pull sprocket up to put on the end of the cam, and it looks like the chain is too short... i think the tensioner has maxed out but i dont want to remove the whole front end for just doing a headgasket...

any help? tips?

as always the help here is extremely appreciated! everyone here has been a huge help to me.

You have to remove the chain tensioner at the front , pass side ,undo the bolt, beware there is spring tension , don't loose the spring or plunger or sealing washer. Fit sprocket once all is lined up then re insert tensioner & tighten bolt. You will loose a little oil but nothing drastic.

Answers to problems you don't have yet:

Worst case scenario is you drop the chain in the pan.

If, while the head was off and the chain fell below the crank gear, it is possible that the timing chain is not meshed with the crank gear teeth any more. Also possible the chain is bound up around the gear and the chain guide. This is a workable situation if you have not already bolted the head down. If, you have not already bolted the head down and, you come to the conclusion that this is the case you can turn the engine , always clockwise, to free the chain and mesh it with the crank gear. Takes patience.

But as stated before the chain tensioner should have been removed for head removal and installation.

If you have already torqued the head down, and this is the situation, do not turn the engine. Remove head. Fix chain alignment. Reinstall head with new head gasket.

When finished, don't forget to prime the chain tensioner when re installing it.
