Continuation from this thread:
Andial 2.9 Engine Refresh on a Budget
Following Tom_in_NH suggestion, I used my HF laser thermometer to check the operating temps for each cylinder in my 83 SC.
I pointed the laser dot at cylinder 4/5/6 exhaust --- actually the intake of heat exchangers, as noted by red dots on the foto. At engine operating temp, dashboard gauge, just above the first mark:
#4: ~ 180 ~ 190 F
#5: ~ 190 ~ 200 F
#6 ~ 500 F !!!!!!! --- why is cyl 6 so much hotter? I measured at least 3 times for 4/5/6 and got similar results
I was not able to reach 1/2/3, so pointed at underside of the head exchanger. Got similar results with 1 & 2 in the high 100's, and #4 much higher 350+.
Does that seem normal, what could be happening w Cyl 6?
CONTEXT: I've revived, and restarted the car, after it sat for 3+ years in my garage. It's been a few weeks now, I've started the car ~ a dozen times, and ran/idled for at least 75 min altogether. It is not running "rough" but could be smoother. Engine shakes more that I'd like to, an it could sound smoother.
Changed/new: fuel, fuel filter, fuel pump, spark plugs, distro cap & rotor.
Adjusted: timing and idle speed
