scotchbrite pad and mineral spirits are pretty easy to come up with. i guess gas is a little easier.

Yep, soak it in Gas overnight and scrub it or power wash it....DON'T sand blast it!

and if you don't get it all clean, it will eventually get crud \ chucks into the lifter bores, bad news.

If you have a machine shop in the area like I do, take it to them and have them wash it in their tank. Mine came out new looking. Only cost me a couple of bucks.

That is the only way to get the dried/caked sludge out of the inside. Have it chemically cleaned by a shop.

I have seen some people grind the spot welds and seperate the two halves then spot weld it back together. Those guys say it is the only way to know for sure you have all the crud out. I personally take to machine shop and have hot tanked that has always been good for me.
