If not, maybe I'll send the other 5 back, get a refund and suck up the cost of at least 1 new injector.īefore I opened up the valve cover I did I quick tug and push test on all the wiring in the various parts of the injector harness while the motor was running. I figure I'll replace the solenoid in number 2 and if it works, great, and I've got a few extra in case it happens again. (Excessive blow by probably from number 6). but, that'll happen when I do the rebuild. Might even go with some kind of upgraded injection tube with better spray pattern, etc. If not for the supposed new factory stock injectors about 13000 miles or so ago and the fact that I'm going to be doing a complete rebuild including injection system in 2 years or less, I'd probably suck up the cost of new injectors as a set. I think the trick might be to get the proper o ring fitment. I could've gotten rebuilts for $250.00 and up or new bosch thru the aftermarket and probably paid extra to get em here quick, but I figured I'd try this first. Still would've had to order and wait til middle of next week. New injectors were only available locally thru a dealer for $875.00 each without the tube. They'll be in anywhere from this Thursday to next Monday. So I ordered 6 of the ones in the middle of the price range ($30.00) from a supplier in the US on amazon. That made sense to me since the duramax is of Japanese design. So I read up on how to change out the solenoid on the injector assembly, did some reading on the parts themselves, discovered the same solenoid is used on the duramax injectors and all the ones I found online throughout the price range were of the same brand - Aisin. The resistance, 1.4 on the 2k scale, at number 2 injector concerns me, though. I'm wondering if there's a way I can keep the monitor hooked up and reading data, while disconnecting the injector splicing, so it reads, but can't do anything. I really like the attitude monitor, though. Yep, that's the direction I'm heading next.
