Paul,

My span= king new GAMIjectors that I installed about 2 weeks ago are each marked (sta= mped) with cylinder numbers. There are other markings on them as well b= ut I do not recall specifics. A quick call or email to John Paul at Tu= rbo Alley would likely get you those details. You would have to not pa= y attention to get them in the wrong cylinder.

The r= eplaced injectors did not seem to be dirty but I did not spend a lot of time= inspecting. They had about 55 hours on them when the engine was opera= ting as a "Performance Engine" plus another forty five or so tach hours oper= ating as a Barrett Precision engine.

I note TCM says they need to be removed and cleaned within 300 hou= rs for "airworthiness" (Tuned injectors only) and I have to add that to my a= nnual checks.

Specifically, there is a patten of bl= ack that is on the piston side of the nozzle in the area where the spray pat= tern would expand. It may affect flow. Cycles in the ultrasoni= c brings them back to new looking but it is taking a long time to remove tha= t substance. I have 768h TT.
