I've had my Cruiser for about 1 1/2 years, a 69 FJ40 with a 71 F engine. The PO said that it had been rebuilt by a high school auto mechanics class and it seems to run well with good compresion, so I believed him. It's always leaked oil, however, seemingly from the main seal. The flywheel cover, tranny, and front driveshaft are the areas that have oil on them. It had the 3-on-the-tree when I got it, but soon converted it to a floor shift. Then the clutch started slipping ( it was supposed to have been replaced when the engine was rebuilt) and I wanted a 4-speed, so we swapped in a 4-speed and replaced it with a new 4-speed clutch. The slave cylinder was replaced at the same time. Now, the clutch is slpipping again, after probably less than 2,000 miles (my speedo is broken). A Honda mechanic and FJ40 owner helped on the new tranny install and replaced the rear main seal at that time. We also installed a new oil pan gasket, but I'm still leaking oil. Could the clutch have become saturated with oil that quickly, enough to cause it to slip? Or should we look for something else? I don't really want to replace the clutch every year, so what can I do to stop the oil leak? (The Cruiser is garage kept and I keep cardboard under it, but I'm not changing the cardboard all the time, the oils not pouring out, just dripping) Could the crankshaft have worn enough so that the oil seal won't stop the flow? GSMTR is less than 4 months away, so any help would be appreciated.
