Okay I don’t have the adapter to put the oil pressure gauge in yet but I have a ecu reader. Out of the three times I have tried it so far the ticking starts at 128 degrees F and 134 degrees F then 140 degrees. Does that indicate a slipped sleeve?

Reason: More info

Sounds like it bud, sorry. Also, given that it starts at a low temperature, a low temp thermostat will probably not fix it. Oil pressure will tell us for sure, only way it is something other than slipped sleeve is if the oil pressure is so low it has a lifter or rocker tick, but that is more uncommon than common. Others have done the pinned liner repair, or you could put in a replacement engine. If you go the replacement engine route I would get a 2002 or earlier 4.0, they never have slipped sleeves. There was a low mileage one for sale on the forums a week or so ago with trans and transfer case for $750, I pretty good deal.
I am assuming that the pinned liner route requires a machine shop that will do it. I will look up details in the forums here. I will post as soon as I get oil pressure numbers. Thank you for your help.

You can do it yourself from under the truck, but it is better on an engine stand.
Flanged liners, or any new liner, definitely requires a shop.
it would be hard to see past the crankshaft. This is a view from the top with the upper and lower intake removed. The box shows the cam in the valley and the lines point to where the cam bearings are. If the cam bearings were walked, you might see them here.
The second picture is looking up with the oil pan off. From a better angle, with your head just so, and a good flashlight, you might see them.
Yeah, I know, this engine was a mess. But as the previous poster noted, if the bearings are walked you will have low oil pressure. It would be easier and cheaper, considering the gaskets and / or fluids lost for a peek, to check the oil pressure and go from there.
