Hello, all; and thank you, thank you!
My temp gauge does not have such convenient degree indicators, but I've refered to that photograph before since I have not obtained any auxiliary gauges yet (by the way, is there a oil temp sensor in the b-18d? I see it in the schematic but not on the motor itself.) What I have done with one of the old thermostats was run the car up with the radiator cap off and wait for indications that the thermostat opened, which I did not observe. The indicator did swing well past the 80 deg C mark, but I did not have a seperate thermometer in the fluid. On the current thermostat, I was very careful when replacing the 50/50 fluid that the heater core was open to drain into and that fluid was entering the upper hose, as checked by squeezing the hose and watching the displacement of fluid and exit of air bubbles, gradually filling and releasing pressure on the hose until no air bubbles came out when sqeezed.
The machine overheats to the extent that radiator fluid is evidently being fried by that smell I've come to know so dearly, and on it's 5 minute jaunts through the neighborhood smoke is pretty evident coming from under the hood and behind the car. Also, it will sputter and respond poorly to the throttle once the indicator climbs to >roughly< 90 c.
But yes, the perplexing thing is this: the hoses, radiator and cap are all cool enough to touch. Hissing is evident at the cap, but not shrieking. Removal of the old water pump revealed an ugly but basicly good pump. Same for the orginal t'stat. Even the old hoses were pretty good. It is equipped with the 5-blade fan, which supplies a seeminly ample supply of airflow.
That water distribution tube might be worth checking, I didn't think to look to closely in there for it's presence or for that matter whatever sinister leprochaun might inhabit the head. And as I've got a good hose around I'll try the release valve too.
As for the black runny residue on the plugs: it isn't what I would typically consider oil as it is far too runny and dries if the plugs are removed after a half hour or therabouts. However, whatever that junk is there seems to be plenty of it in the oil removed from the engine after 5 weeks in and 5 miles on the car. The oil pressure light does not come on at idle or under load or when over heated, but it has before when the engine was initally misfiring badly so I don't suspect the gauge any more than I do the Temp gauge.
I removed the distributor when doing the timing and w/ the engine at TDC #1 the marks on the gear were oriented as they should have been.
I'm currently debating the value and merit of putting in calibrated gauges vs. a brake master cylinder, but I've got a good battery and a recently operable generator so I'll do the compression test now that it's in tune. If it points to the headgasket we'll see about that and the coolant dist. pipe, if it points to the bores someone in Sacramento will probably see the car in the paper... those of you are hereby forewarned!
Again, thanks immesureably. Pleasant holiday...
-Sean.
