Re: Trooper 2.3L Head
Well, the new head is on with a new radiator, I just need to find a few consecutive hours to run it in, then adjust the valves. Problems encountered: (1) fortunate on the exhaust manifold bolts; most came off OK, but had to leave a few studs in the head (returning it for core), then bought new studs for the new head, (2) the air pump line between the exhaust manifold and the intake that runs behind the motor (3/4" tube) had to be cut to clear the head removal, since the tube fitting on the exhaust manifold wouldn't budge, patched that with some flex hose, (3) the timing belt removal (for the cam replacement) did not go well, since the belt was off by one tooth; fixed that but did it at #1 TDC (which the manual recommends) instead of #4 TDC (which is the real setting, from a recommended source here). I plan to start an run it in next week (the truck is not going south to Hatteras this weekend...d*mn!, guess I'll have to run the '89 with the Bronco), and (4) I cross threaded #2 cyl spark plug in the new head, but was able to chase and clean it up.
I didn't get into the bottom of the motor, since the cylinders were clean with no ridge (in spite of 155K!). Hope you are as fortunate.
What problems are you seeing in your '86? I have had three '86's (retired two of them at 195K and 167K, respectively), and have done about everything to them. The one I am replacing the head on bent a #1 exhaust valve due to a failed timing belt tensioner; it also overheated due to a head leak and clogged radiator.
Send me a note if I can help.
