Seems like a bargain.
I just spent 85.00 having a block and set of heads baked , and they came back cleaner than I expected.
I believe the EPA has some issues with the caustic soda soaking process.
I don't know anyone that does it anymore , but the problem was what to do with the residue inside the tank after doing a bunch of parts.
At the tech school I went to , they drained the tank , then shoveled the remaining goo into a 55 gallon drum.............this was early 80's and no one cared much how you got rid of the sludge.
Now , you could probably still do it , but the permits would not be cheap.
Exactly. The shop I used had to stop because they could not find anyway to legally get rid of the wasted vat chemicals. The EPA started coming in shops and fining people for even having it on the premises. They bought a Hugh oven that really cooks the parts and turns the gunk into powder. They used the shot machine after that. They cleaned the blocks really well and I always clean and brush every hole. I never had a problem. His shot machine kept breaking so now he sends them out to be blasted.
