Timing Chain replacement
I thought I had read awhile back that there was a source for replacing
the timing chain (IMS to CAM) without having to split the case?

anyone have any pointers?

thanks,

Someone did post on the subject in the 911 forum, but if memory serves Mike, he was talking about splitting a link on a chain and trying to fish the open chain around everything. Unfortunately, I think that is a bit of a "fool's errand" as I have never heard of anyone doing it successfully...............

I don't know about the engine in question in depth, but I've "rolled in timing chains" on various cars.
If you have access to the chain where is rolls over a sprocket it should be doable.

So far as "TIPS":

Turn OFF radios. tv',s etc while doing procedure...
Use plenty of LIGHT while doing procedure.
Stuff area full of rags to catch grinding debris. (You might be able to make a shield out of aluminum foil to catch debris)
Take inventory of how the link you're taking out is constructed, While pushing out link have a powerful magnet to catch link sections. Count /compare to make sure nothing has been left behind.
Use a helper while rolling in new chain. (Helpers job is to keep tension on old chain coming out against socket)

Be ready for times chain will try to jump EG: When valves are coming on/off compression.
Attach new chain to old and roll it in.
(Taking out spark-plugs makes things easier.)
Stuff rags in area while installing master link /last link.

Make sure the link master link is facing in right direction.
Inspect area for grinding debris- remove.
Make sure engine is still in time before buttoning up.

Depending on how good you were policing area- change engine oil, and or maybe just the filter.

Sure, it's difficult but doable, because you can clip one end of the chain and feed the other around. This works on both the 3-chain and 5-chain motors with every chain except the one in the middle. However, I think chain wear / "stretch" is probably the least of anyone's concerns with these engines.

Can this be done since they do not sell a chain with a master link?
