Hey all,
I'm gearing up to catch up some maintenance on my 1997 FJZ80. I've done a mild tune up at 170k and going to do a major tune up right now, at 230k. This includes replacing leaking valve cover gasket, as well replacing almost all of the gaskets, coolant lines and vacuum lines under the intake manifold. Removing & cleaning injectors, dizzy oring, coil pack, fuel pressure regulators, PHH, deleting rear coolant lines, as well as replacing power steering pump& hoses. My FJZ has three noticeable leaks, one is from power steering pump, one's from rear main seal (I think) and the third one is from what I assume to be leaking valve seals. I burn about a quart of oil every 500-700 miles. I *think* my head gasket is still fine as my coolant looks great & my oil looks great also. However, while I'm in there and doing all this work, would it be worth to go ahead and refurbish the head, or just wait til the head gasket blows. If I'm to do the head gasket, is it worth doing all the timing belt components & oil cooler? I have replaced the front main seal & oil pump seal few years ago and it's still fine. Is it easier to take the head off with the block still in the truck, or go ahead and pull the whole engine+tranny and service it all out of the engine? And If I do pull the engine, is it worth to go ahead and get it completely rebuilt with new bearings & rings.
Someone take me out of this rabbit hole, thanks lol.
