I was thinking the hydraulic tensioner is wore out, once it get oiled its quit as can be, it not hard to get to rear back of head. Just bought, need to drive, but will look for a low mile engine and probably change the cartriges out on them while out.
^^^This^^^IMO, it is decision time, repair or replace engine. The only sure thing at this time is the engine is coming out.

|I got $500 for my v6 with 100k on the clock, that was 4 years ago. Guy told me he had a difficult time finding a good used 4.0.

In the mid-late 90's there was a young guy that worked for my Dad in his dealership for a number of years that would drive an Econoline van into his work space at 8am, pull the bad engine, install the replacement engine and back it out 100% done before 5 pm at the end of his work day. He did it several times. And he took two breaks and an hour lunch. Now if you ever worked on, or even thought about working on, an Econoline van you know this is no small feat.

We did a v8-swap on a s6/manual once. It blew ass trying to find and fit small, fiddly-ass parts like linkages and mounts, harnesses and the like.If I were to guess, they were tough as nails and could swallow a lot of stuff.
It's becoming increasingly difficult to find low mileage 4.0 V6 engines since their production ended 11 years ago so I suggest you remove your existing engine and refresh it with new timing chains/guides/tensioners, new rod/main bearings, new piston rings, new oil pump, and new gaskets/seals. If there's a ridge at the top of each cylinder, you'll need to have them rehoned. Do it once, do it right, and you'll have an engine that'll last at least another 100k miles. You could also use the opportunity while the engine's out to bolt on a pair of headers and underdrive pulleys to add some performance.I was thinking the hydraulic tensioner is wore out, once it get oiled its quit as can be, it not hard to get to rear back of head.
