my 91 dodge has over 316,000 miles 81 chevy luv just turned over 186,000 and stuck and my 82 chevy with a 4bt who knows on the motor I only have a couple thou truck has about 140,000 on it.

Sounds like my (non turbo) isuzu diesel when you pull the air filter. I wouldnt worry about it.

I have heard that they run an HHO device on semi trucks in canada. If I remember right some started doing this about 5 or 6 years ago, Maybe some one up there could tell you how it worked out. Sounds like a bad idea to me though.
