I have a 2001 Jeep Wrangler TJ that has had cylinder 4 & 6 misfire codes.

Today I removed the valve cover to see if I could see any coolant in the valve train (thinking I had a cracked cylinder head) and discovered 1 push rod missing/down in the block (removed with magnet) and 1 push rod loose and free floating.

I am mechanically inclined enough to swap out parts, but am far from an engine doctor. What would cause this? And what is the next step(s)?

Thanks in advance my fellow Jeepers!

i had that happen on an old chevy 350 but i never knew why. my dad said maybe a lifter leaked down over night and when i started it, the push rod was out of its normal area and popped out. on my truck, the push rod was bent so you could tell the arm hit it and caused hte bend which popped it out of place. maybe yours are leaking down too? i would run some engine flush or diesel through the oil system though because your head is black and looks terrible where it should be more of a golden color from teh oil. yours is very gummed up looking
