So I am just finishing up my 3rd. set of injectors and starting wondering...
Can anyone tell me what happens to the injector tips other than getting build up on them? I was looking at my tips and wondered if I remove them and place them in an ultra sound cleaner would that work? Or do the tips actually degrade from use?
I don't think it would be much to build a pressure pump to check the spray pattern. Probably use a harbor freight porta power pump some old fuel line fittings and a valve?

Thanks Chris

Might want to switch to the newer SAC injectors.

mray, that's what I did this time, SAC00 from LDS. That was the reason for my question. I would like to save those nozzels next time around. When I removed the Bosch injectors what I saw was quite a bit of rust in the inlet of the injectors and that is what I supposed created the problem. Even though I run the Air Dog and a Cat filter.

The tips degrade and wear down over time. It’s the internal ball that starts to wear them down. I saw some photos in a YouTube video some ex marine kid in Southern California put up that explained it and showed the damage.

I'll look for that. But if it's like you say then it's another expensive tune up down the road. I am hoping that everything I have read about the SAC injectors holds true. But I know they can't prevent rust, and apparently neither can the air dog with it's water separator :-( I change all fuel filters every 8-10k).

The ship I was on when in the Navy we rebuilt/tested the injectors every year, I believe. Much different type than what our in our trucks, but someone is out there rebuilding/testing our injectors. Shouldn't be too much of a stretch to rebuild them yourself, though the tools required might not be cost beneficial.

For those interested, the engines onboard the ship were Colt-Pielstick (spelling?) V16's, twin turbo rated at 8,000 hp with a max rpm of 598. 2 main engines per shaft, two shafts. Each cylinder was a bit over 3500 cubic inches. Sipped fuel compared to the 3 steam ships and one gas turbine ship I was one.
