OEM only or leave it alone for the hydraulic tensioner. The after market stuff is junk for the 4.0 SOHC timing components.
Doing the valve cover gaskets is a good idea while you are in there, I did mine at the same time. They are a pain in the @55 if you try to do them with the fuel line and heater hoses still attached but it is possible. For the fuel line that goes over the D/S I removed the one little bolt holding the bracket on that the fuel line is attached to. That bracket is bolted to the cylinder head and that little bolt is a pain to get to. I did it that way because I didn't want to mess with opening any fuel lines and creating a smell in my garage.
The P/S I unbolted the bracket that is part of the heater pipes/hose assembly after removing the transmission dipstick tube.
This enabled me to sneak the valve cover out without draining or loosing any coolant.
The valve cover gaskets will stay on if you assemble the valve cover bolts with new seals into the valve cover and through to the gaskets properly. There is a shoulder that goes through. Here is a video that will explain how to keep the valve cover gasket in place while you turn the cover over without it falling off. (hopefully).
if youre pulling valve cover gaskets, probably already know this, but inspect the one timing chain that goes to the p/s (?) to make sure the guides are alright
Check both sides while you are there.
If the passenger side looks like this, you are in luck!
And make sure the driver side is still in good shape. This picture didn't turn out so good but this is the area to look for broken plastic chain guides.

Ok will do. I am gonna take my time to be as thorough as possible. That is one very clean engine. Thanks for the heads up. All this info is really great.
