Here is a copy of Dave's email..... enjoy ;-) Hi folks, About 2 years ago my 82 BJ42 started to act up on start up, white smoke, missing, clanking and generally pissing off the neighbors. Being the conscientious citizen I am, I delved into the problem forthwith, besides, the fuel mileage and power were in the toilet! Injectors were pulled and cleaned, filters changed, timing and valves adjusted, but this brought little relief. So I decided to ante-up the cost of new nozzles and the set up of said nozzles, not chicken feed by any stretch. Imagine my disappointment when this also failed to produce the desired results! So back to the drawing board, one night I decided to do a compression check, this did nothing but confirm the incredible longevity of the 3B, all readings at or above 400 psi, this at 250,000 K. I then pulled the injectors, low and behold #3 was covered in soot - not much fire in that hole. Fearing I had a problem with the #3 delivery valve I decided to do the baby steps route and changed the #3 injector line. Morning breaks, crisp and cold, perfect for the first test start. I fire her up and straight away my baby is revving like a Ford Cosworth on the start line. I take my 94 hp racer to work, grinning ear to ear. So, problem solved, can't find anything wrong with the injector line but I'm happy and I put it down to a possible kink or blockage and get on with life. Some time ago I read a post to the List about the compression fitting end closing up and restricting the fuel flow, aha! seez me, that's the ticket, I'll watch out for that. As it happens earlier this week the truck began to have the same symptoms as before. So today, after fiddling with my transfercase mount, I pulled all the injector lines and drilled out the ends with a 3/32" drill bit, cleaned them carefully and reinstalled them. On start up, the first thing I noticed was how smooth and even the engine was running, on checking the tach I noticed it was running 300 rmp above her normal idle speed. I turned down the idle to normal, now its sitting back on the factory set stop, and it's still running like a sewing machine, oh yah baby, I'm happy now! So, the moral of this story is; before you all go and get excited about changing out immense quantities of expensive electronic and mechanical parts, get that out that High Perfomance 3/32" Drill Bit and give her a go, you may be surprised!

What caused this was the delivery valve that had turned loose when removing the injector line though the clamping that secures the valve was untouched.
