Goatmack2 Posted February 2, 2012 Share Posted February 2, 2012 I'm new to the forum here with a question about a project truck. I have a B61 with a thermodyne diesel that I acquired recently. I don't know the exact history, but I do know for sure that the engine was running when it was parked about 10 years ago. Now I have the truck and the engine is set up tight. The body and frame are in great shape from the previous owners restoration efforts, and I'd like to get it at least turning over before I do anything else with it. Any ideas on where to start? If it were a more modern engine that i was going to rely on for power i wouldn't even try to get it going without a full teardown, but I'm wondering if there's any quick tricks or common problem areas with these engines that I should look at before getting into a full rebuild.

Superdog Posted February 2, 2012 Share Posted February 2, 2012 If it was mine,I'd pull the injectors and start soaking it with some sort of penetrent.Everybody has a different favorite it seems,straight diesel fuel,diesel and ATF,Kroil is good.Let it soak good then see what happens.

mackmixer Posted February 4, 2012 Share Posted February 4, 2012 I have always used transmission fluid. Ran into an old guy last summer who restores tractors (gas & diesel) and he uses hot cooking oil, Crisco like his wife cooks with, to unstick old tractor engines!! Fills the cylinders and let them soak in for several days before turning over. He swears by it. So heating up trans. fluid, penetrating oil, etc. before using may help.

Olivetroad Posted February 4, 2012 Share Posted February 4, 2012 I've had good luck with PB Blaster freeing up stuck farm tractor motors.I'm with you - PB Blaster - easy to use right out of the spray can. If I had to heat it up, compared to me Richard Pryor would look safe. Quote Link to comment Share on other sites More sharing options...
