    90% sure that I blew my head gasket at GSW. What else should I do while diving in there? Already planning on the intake plenum, h2o pump, bypass (choad) hose, radiator. My NOx was a little high on the last emissions test, so it's been suggested to look at the EGR system. With everything out of the way, would be it worth to put a new timing chain on it while I'm in there?

    Yeah, your kid has it now, lol. And doing the head gaskets is still less work than moving everything over!

    A good coolant flush not just a drain/refill! And it could be time for the turbo While your at it!
    "ZJ's were designed with the intention to take 1 really good hit, and fold up. As long as the occupants walked away, it was a success. In the wheeling world, we expect our vehicles to take multiple really good hits, drive out of it, and run the obstacle again!"

    Funny you should mention this. The WJ needs a new head gasket and I am researching the same question. Are you having the heads rebuilt? The 4.7 heads like to drop valve seats so seems prudent to have them done.
