2.5l ?

This is a great write-up. I've got a 2.5L '98 TJ that will likely need the head gasket replaced. Is there anything significantly different about the 2.5L I need to know about?

I'll take pics and post the 2.5L head gasket replacement job when I get around to doing it, which should be within a month or two.

So are the valves self adjusting? I have a spare head that is 200miles old. I was going to put this on my 200000+ zj. Will I need to do anything different on reassembly with valve adjustment shimming or is it magical. ??

When I go to loosen the rocker arms they move with it. What do I do?

Awesome Right up, Helped me get things apart in a timely manner. Only question I have : Do I need to find TDC during the reinstall process?

Great write up. I'm currently in the process of changing the head gasket in my '93 cherokee and I've been using this write up and it's helped a lot. But does anyone know where I can find the torque specs for the head and rocker bolts?

2.5l

Just a follow-up, I did end up replacing the head on my '98 4 cylinder. The procedure is the same; very little difference except more room to work in.

You do not have to find TDC for this procedure. Also, the rocker arms require no adjustment, just tighten each side of each individual rocker arm 1 turn until tight then torque to spec (21 foot-lbs for the '98 TJ).

Use copious amounts of PB blaster to spray down the exhaust and intake manifold bolts. I sprayed them several times over the course of 3 or 4 days and they all came off with no issue at all. I've heard a lot of nightmares of broken bolts and with a jeep as old as mine I took them to heart. PB blaster was a Godsend.

Any luck on this? How did it turn out?

I just wanted to tell you what a great job you did on this post. Thank you! You encouraged me to attempt this repair on my 97 Jeep Grand Cherokee Laredo. I hope there is as good a post as yours for that model.
