What else should I do while 4.0 tore apart?
Hello all I was planning on doing a freeze plug job tomorrow but no where in town has them in stock so I have to order them in. This gives me a little time to think about what else I may want to do to the truck while its tore apart. I just bought the 1997 2wd with 162,000 miles. I don't know anything about the history but it seems to run well with the exception of a leaky valve cover and a really bad leaking freeze plug. Here is what my original plan was:
Replace the 5 freeze plugs on the side of the block
Replace the Intake and Exhaust manifold gaskets since they have to be removed for the freeze plug job.
Replace water pump since its cheap and it may also be leaking coolant.
Replace valve cover gasket
I've already replaced the oil and filter with Rotella T-5 10w-30 and a motorcraft fl1a. I haven't serviced the tranny yet but its shifting really smooth as is. What else might I want to service while the intake and exhaust manifolds are off? What else should be looked at with a used ZJ when you don't know the vehicles history? I am planning on taking this truck on the road, 500 miles or less trips and I want to get it in good shape. Also I'm gonna coat the back of the freeze plugs with rtv per Oldfrogs recommendation, should any of the other three gaskets that I'm going to replace get rtv? Thanks for any info guys.
