SOURCE: I am trying to replace the lifters on my 2002 jeep

remove valve cover. Lifters are under camshaft

SOURCE: can a 2004 endeavor use 2003 montero lifters

I looked this up and got that a 2004 endeavor has a 3.8l and the 2003 montero has the 3.5l engine. the oil filters have different part numbers for each engine.

SOURCE: I just replaced all of my hydraulic lifters and no compression!

Yes, you've overtightened the lifters causing the valves to not close completely. If you did not prime the new lifters before you installed them and tightened them with the engine off they are most likely collapsed. back off all of the rockers to just snug and make sure the engine is running when you readjust them. Usually you need to let new lifters sit in a can of oil for a while to fill up. I've used a syringe to fill lifters prior to installation. Did you replace the push-rods also? If so were they the same length as the originals?

Testimonial: "Very helpful and it had confirmed what I did. The push are in good shape. The lifter were primed in oil. Thank you very much your help. Aloha!"
