I actually have an infrared thermometer…it is quite handy for many purposes. Unfortunately, on the MB 617 turbodiesel engines, it is not really possible to get a good reading at each exhaust runner due to it’s configuration. The exhaust ports pretty much dump into a log type of manifold, with very short primary tubes (if you can even _call_ them tubes) and they look to be siamesed on cylinders 2&3 and 4&5.

Two of these *wonderful* rebuilt Bosch injectors are leaking past the disc valve so badly that the fuel lines lose pressure in a matter of a few minutes! The ball pin in the prechamber is wet when I remove the injectors. It is hard to imagine the idiots in the rebuild facility could screw things up this badly. The reason that I decided to go with genuine Botch, er… Bosch rebuilds is that they (supposedly) use new tips on all of them – they do not re-grind them. How could they possibly screw them up? (asked rhetorically, of course; as they did find a way to do so!)

Thanks Again Everyone!
