manually rotate engine?

[G-RELL]

Real quick..

Working on installing a new secondary chain on my 2000 3.9.. The drivers side chain snapped and has a broken tensioner...

right now, the flats on the cams are both facing down. I need to get the intake cam rotated so i can line up the exhaust cam to install new chain. Can I rotate the engine buy hand (clockwise) with the bolt holding the cam pulley on? (socket an cheater bar?) if so, do I need to remove the exhaust cam completely to make sure the valves dont get in the way...or at this point does it really matter.

just want to make sure im not missing anything

Yes, it can turn it that way. Just don't turn it backwards.
I wouldn't think that it would matter to remove the exhaust cam. Surely, any and all damage to be done happened when the chain broke. Just go slowly and gently.

If they are both down then they are in sync. When turning the crank (and intake cam) go in small steps and rotate the exhaust cam also in steps to keep both cams in time.

thanks guys... yeah i dont know how off they are, but i do know its been cranked a few times to it could be off a bit.. the chain and tensioner broke.. should i be worried about any parts or pieces floating around? drop the oil pan maybe?

Yes. As easy as the oil pan is to remove on the V8, I would certainly do that.

thanks buddy

There is a particular sequence to use when tightening the oil pan bolts when you put it back on.

k... so i got the flats lined up, I was only able to get the engine to rotate so far (could be just because i had bad leverage) but enough to get the flats visible and exhaust cam lined up...

now i need to remove the broken tensioner.. would my best option be to remove the exhaust cam gear? appears to be held on with just the main bolt. If so (after i mark it) whats my best method of breaking it loose without the cam turning???
