Test drive went well, Oil pressure came right up (should figuring all the pre running, no noticeable leakage of water, some oil around drain pan passenger side, but I suspect that came from when I installed the full oil filter. No "funny" sounds, just normal Datsun engine. I will get a couple cans of brake clean (I never seem to have enough of that stuff) and hose off the under side around the oil pan to be sure. there was some anti freeze trapped on suspension part under the water inlet, I think that came from when I re attached the heater hose, I blew it out with compressed air, towel dried it. It seems like a natural catch place for water anyway. Had the squeals from the belts, alt most likely, I tend to install too loose, trying to not over stress the water pump. Maybe a new belt is in order, will pickup when I get the brake clean. Next trip will be to south florida, South beach, pretend I am sonny crocket, cruise around at O dark thirty. The beach is fun then, cool and feels like going home again (but for all the new roads anyway). Maybe drive around the old hood and see what's happening. A nice short trip to really give it a test, before tail of the dragon, then maybe plan a trip up the North East. I would ultimately like to drive in Canada, maybe up the Yukon, but that will take a lot of time before I think I can get up the nerve to test the long range of the Z again.
