cracking open the cam shaft cover

[broken2bfree]

Am a little confused about what tool to buy to hold cams in place. Pelican recommends a $235 camshaft securing tool. Can I just use the cam shaft lock that comes with the ims bearing puller? I have to get in and replace a chain tensioner and the last thing I need is to add to my grief by getting timing outa whack.

Are you doing the IMS bearing? I just did this on the Saturday before Easter and I used the cam lock included with the IMS bearing puller; you shouldn't need to buy an additional lock. It will include one for the five-chain motor and one for the three-chain motor. As per the instructions, you will turn the crank until the motor is at TDC, lock the crank, and you should then be able to install the appropriate cam lock on the passenger side bank.

I will be replaceing the bearing, but my main issue is with the chain tesioners. One of them is chewed up and needs replaced. I am hoping to use the lock that comes with bearing puller to do chain tensioners.

Why are you removing the cam cover to replace a chain tensioner? The four tensioners come out their own ports without removing the cover, but you will need to lock the engine at TDC and lock the cams using the IMS tools to remove them:

The pads are chewed thru. Not positive of which one. but pad is gone and chain is into the aluminium, I will be pulling the tensioners as pictured either tonite or tomorrow, and that may give a clue as to which one is bad. It is believed that the wore pad is the ims to cam chain tensioning pad. As much aluminium as i had in the filter, the chain may be damaged.
