Howdy. I aquired a 71 duster that has a stuck 340. I pulled the plugs out and was going to squirt something in the spark plug holes and let it sit over the winter. What is the best stuff to use? Thanks
For all you know... the crank could be broken.
I had a 70 340 4 spd duster once that just wouldn't crank over to do a leak down test on... I put a 1 1/4 on the crank bolt and could turn the crank back in forth a decent amount...but the starter just clunked.
I said fk it, rolled the cherry picker over and yanked it out. Yanked the oil pan and there it was... broke behind the no.1/2 in front of the main.
