removing the m30b35 head tommorow for a headgasket change

[The Bigfella]

I got the M5 injectors done for $15 each - it was $20 each until I waved folding stuff. He reckoned they were filthy.

Mine's back on the road (last Tuesday) and run in - courtesy of a trip to Brisbane and back - time to get a hurry on mate!

I don't know his name (no receipt) - but he came to us in North Parra, where I rebuilt the engine. He's a mate of the car repair shop next door to my mate's place. I can find out his number tomorrow if you are anywhere near that sort of area - he's a mobile injector guy.

I'm a happy customer (the car is flying now).

I go a put the cylinder head back on today, for some reason totally unknown to me, the crankshaft wasn't on 0|T must about 3/4 of an inch off. also I had to rotate the camshaft slightly on the head. When the timing chain is lined up to the head you can see in the picture below,



that the "sprocket locating dowel" is not in the correct place. It should be were it is circled in yellow. This is when the crankshaft is on O|T.

Weird thing is the timing chain never came off the sprocket and Nick and I removed it with the crank at O|T and the camshaft it's it proper place according to the Bentleys manual.

Can I leave the crank in O|T ,take the sprocket off the timing chain. Move the cam to the correct position and then reinstall the sprocket in the right place with (obviously the chain attached)?

EDIT: I've been told;

real briefly... if your 100% sure that the crank and chain didn't move, then adjust the cam for it to fit.

I don't think this is wise though. I've been told that "leave the crank in O|T ,take the sprocket off the timing chain. Move the cam to the correct position and then reinstall the sprocket in the right place with (obviously the chain attached)?" this is fine.

What do you guys think?

id get the crank on ot and align the cam as per bentley, it's been a while since i did a m30 but if i remember right with the cam at tdc both lobes on #1 will be pointing down, it's one of those things if i was there it'd come back to me and id have everything in position in a few seconds

Unscrew the timing chain tensioner, its taking up too much of the slack and thats why the gear won't align with it on tdc.

The chain can slip off the lower sprocket real easy, especially if the crankshaft was rotated.

I think (just MHO) that you align the crank at o|t and the cam with the two #1 lobes pointing equally "down", i.e., both equally offset from the "down" defined by the centerline of the engine, not by gravity. I'll have to learn for sure pretty soon here... my turn comes in a few weeks after the head comes back from the shop. Glad you're going through this first so I can learn...
