What's the leak down

1 out of 1 people think this is helpful.

the distributor cap is cracked...look for carbon traces...shower it in WD-40 and see if it fires right up~

leak down is when you have a compression gauge and a stop watch...see how long it takes to reach ambient pressure conditions...comparatively can be useful data to find out which cylinder is weakest...can be done wet (with a few drops from the oil can) or dry (commando)~

Swap out the plug wire that melted and see if you have the problem on 6. Swap wire 6 for 7 and see. How does the dist. cap look?
