Putting new engine in TJ, what should I do to the engine first?

I just bought a 97 TJ with a blown 2.5 liter engine in it for really cheap...I have a 2.5 liter engine out of a rolled Jeep that I am gonna put in, but now I am wondering if there is any work I should do on the engine before swapping it in? I was already thinking about the rear main seal, valve cover gasket, etc...I would just like to replace stuff that might be an issue later down the road and would be easier to replace or fix while the engine is out of the Jeep.

Thanks,
Andrew

If you have the time, space, and equipment (and are really that concerned about it). You could put the engine on a stand, pressure wash it, and buy an engine gasket set and go to town replacing all of the seals and gaskets (obviously don't go replacing a good head gasket. WHile you have the valve cover and oil pan off you could clean out the engine oiling system really good. But, that's just if you feel like doing all of that just for a warm fuzzy...

Man I'd have a hard time putting the 2.5 back in. Have you considered just finding a 4.0?

What would you suggest is the best way to clean out the oiling system? I wouldn't mind taking the time and putting in new seals and gaskets, even if its just for the warm fuzzy.

@hefightsfire = I thought about putting in the 4.0, but I have the 2.5 liter already so I am just gonna put that in, plus its an easier install then the 4.0.

With the engine on a stand and the valve cover, oil pan and manifilds off you can put a large drip tray under it, set a container of solvent so that the oil pump pick up is submerged, install a new oil filter, and spin the oil pump with a drill. Or you can re-install the oil pan without a gasket (after you clean the inside of the pan really good),re-install the valve cover without a gasket, install the new oil filter, fill the oil pan with five quarts of solvent, and spin the oil pump with a drill.

DO NOT turn the engine with the solvent in the oiling system!

Do this BEFORE you install any of the new seals!

After you do this, install another new oil filter and repeat the process with fresh oil to get ALL of the solvent out of there!

Replace ALL of the seals (other than the head gasket, but including valve seals) after you do this.

After you install the engine, be sure to use engine break in additive with high ZDDP.

I would probably go the re-install oil pan and valve cover with out gaskets route to avoid a huge mess. Be sure to clean the oil pan and valve cover really well first.

Make sense?

Differential gears......

I want your factory 07-up take-off/thrown out JK front/rear Lower Control Arms! Bent ones are perfect also as long as the bushings and cold cut rings are in good shape/useable
