B-12 from AutoZone but it's a degreaser that works well simple green works good from what I hear and alot of elbow grease have you tried oven cleaner ?
I don't want to use anything that I have to rinse with water. I did this out of order. I should have cleaned and painted first, and then tore it down, but I am stuck with it now.
I think I'm going to concentrate more on the parts you can actually see. I don't really care if the paint on the oil pan has specs that came off. The block is mostly black already, LOL.
