OK update on BIG AL
All work completed on the motor now. The new leads look nice with the red and blue. I couldn't get them on because they disappear into the bowels of the motor; so I let the mechanic do dat.
I checked his work. There was no blood so I guess he didn't skin his knuckles.
BTW, I have some good news ...
Fuel consumption did not increase over night while BIG AL was in the garage!
