I removed the intake and exaust manifolds from my m151a1 that has been stored inside since I bought it in 1982 at a base in NJ--I noticed the intake valve stems were carboned up and loaded with sludge--I rembered at Harbor Freight they had a small top loading sand blasting gun for sale and they also sold fine ground wallnut shells--I bought the gun and the shells -- within 5 minuets of work all intake valves looked great--I blasted each valve when it was closed and covered all openings----the wallnuts will burn off if any get into the cylinder and the shells soft----It was the first harbor tool that exceded all expectations-------very handy and the cheap--the gun was $16 and the shells are $25 for 25lbs--I used about 1 pound for the whole job---good luck with your projects
