Been putzing around since 04 with a complete frame off including complete rebuild of my 3b motor. Spun bearing did alot of damage and had to replace cam, pistons, liners, rocker assembly and so on... Decided to start it up last Sunday to make sure it runs, check for leaks and other problems. No oil pressure on cranking. I used lots of assembly lube and added lucas break in addative for the zink so not too worried about initial cranking wear. No prime to oi pump so bought a cheap garden sprayer and pumped in 2 quarts extra of oil through the pressure sender hole. Took out the glow plugs and cranked over 3 or 4 times, 10 seconds per. lots of oil from rockers and pressure gauge show lots. Sucked out the extra oil, back in with the glow plugs, bleed the racor and factory filters, bleed the pump. Start it up and bleed the injectors. Smoothed right out and let it run at fast idle for 10 minutes. Lots of talk about the best muffler... I have no turbo and head pipe is 2 &1/4" to a polished stainless muffler off a new 2009 mustang that I acquired for $35. It exits in front of the back wheel. Sweet sounding, not too loud. There you go. Questions. 1)..Alternator is very hot to touch, got the feeling if I spit on it it would sizzle. How hot is too hot and why? 2)..My fan clutch is sloppy and I need to source a new one. Any ideas where I can find one?? Lordco and Napa here are a waste of air. Toyota are very happy to tell me yes we can get one for you for $350. or so ... Any leads on one reasonably priced would be appreciated as would thoughts on hot alternator.
