I am just replacing my noise timing chain on my 2.5 V6 GV

I found the problem which was just a slack timing chain rattling on the guard. Have the kit to replace it but there is also an oil pump chain.

To get to the oil pump means putting on a hoist removing rack and piano assembly and diff housing.
With NO hoist (coming in a few months) this is a big problem for me to do.

I know if I had the hoist I would go ahead and do it, but not having a hoist is this going to give me grief ? I mean there is no problems with it so I think just leave it alone and do the timing chains ???? Thoughts anyone.......

I would just leave it - the oil pump chain runs partially submerged in the oil, so it's well lubricated & I haven't heard too many people complain about it.

thanks, that's what I figured. Cheers Mate

If you are doing the other chains, you will have the timing cover off & can adjust the oil pump chain guide - it doesn't have a tensioner as such. The oil pump chain is the shortest of the lot, but only a single row & like fordem said, is always running in oil (as long as there is correct oil level in the sump).
There is some warning I believe about not removing the sprocket from the pump - don't know what goes wrong if you do & I'm not going to find out!.
Unless the sprocket teeth look worn or there is not enough adjustment available with the guide to take up the slackness, leave it there.

I believe it is simply a "press fit" - the only person I know that removed it, had to tack weld it back in place - the welds have held for several years, so I guess no harm done.
