I have a new-to-me 1990 22RE 5-speed 4x4 that broke a timing chain lat week on the way to work. Since I canÆt afford the ridiculously high estimate the local mechanic gave me, IÆm trying to repair this on my own. IÆve got a few questions for the board:

1) There is a large wiring harness that runs through the air intake manifold. The harness seems to run forever in each direction. On one side it runs down along the transmission, transfer and then across a cross member and up into the cab. The other side splits into two sides: one runs along the fire wall to the coil the other runs by the fuse block and the diagnostic port then into the fire wall. Question û How do I get this out of my way so that I can remove the intake manifold?

2) Two of the head bolts were so caked into the head with carbon build up that I had to remove them with a crow bar and repeated drownings of PB-Blaster. Is this a sign of something more ominous to come?

Thanks for the help.
