Anybody know of a shop with a mechanic who can work on a Detroit 6v92 in a '94 U300 in Southern California?<br/> <br/>I am losing oil (one gallon per 500 miles or so) at the back of the engine where it meets the transmission, and am told that a repair requires a lift and transmission jack. So... not only am I looking for a guy with the skills to do the job, he also needs access...
