1500 mg midget
A little over a year ago I rebuilt the engine (new pistons, rings, bearings, etc).
Last summer while driving the car it was overheating a bit (getting to about 210F).
This winter I have replaced the radiator with a new one (the old one had a lot of deposits in it). The car has set without coolant for about 3 months.
After getting the car running again this weekend with putting new coolant in it, I am getting a lot of smoke out of the tailpipe (it appears white maybe a littel grey or blue). Also the cylinder 3 & 4 spark plugs are black with soot, 1 & 2 are clean. The smoke does have a smell of fuel.
Before I did the work on the car, I wasn't having this issue. I also did check the plugs recently last summer after the overheating and they were clean.
The only thing that has changed is a new radiator & coolant, car sitting since last September.
My thought is that with the car sitting with out coolant for about 3 months something happened to the head gasket, but that wouldn't explain why 3 & 4 spark plugs have black soot on them. I have done a compression test on 3 & 4 and had about 140 psi on both cylinders. I plan to do a leak down test on all the cylinders soon.
Any thoughts?
