Yesterday I disassembeled the 85k mile motor that was in my '91 when I bought it. This is the motor that had lost the main front pulley bolt and was driven that way until the main pulley boss slung off the e-shaft. Telling by how much oil was in the engine bay it was driven that way for quite a while. BTW: I don't think the bolt was completely backed out but it was loose enough to leak oil and finally sling the pulley off.
Because of exposure the front of the e-shaft has a bit of surface rust from sitting with out a pulley boss for over a year. Nothing major. I think the rust will polish right off and not effect anything.
The key that indexes the main pulley boss was sheared half way off. It took a pair of vice-grips and a dead blow hammer to get the key out so the oil pump chain pulley could be removed. Everything on the e-shaft looks good, I need to check bearing clearances and runout but I think it will be usable.
Pulling the motor apart was somewhat routine. There was much more carbon buildup than I expected on a 85k mile motor. The side seals were still floating but the apex seals seem to be stuck. I think a few hours in the parts washer and the rotors will be perfect. Amazingly the side and rotor housings look near perfect. The only blemishes on the rotor housings are where the small piece of the apex seals makes contact, but there is no fleaking and no scratches.
The odditiy I found was some brown jello like goop that FILLED some of the cooling passages. When I pulled the rear rotor housing off the middle housing this goop was sticking up and retained the shape of the cooling passage in the rotor housing. It was slimy, smooth and smelled very bad. What causes this?
