Help: LBZ Injector Test Report

tjZ06 · Jul 28, 2015

Hey all, a good friend of mine is replacing the head gaskets on his '06 LBZ ('05 build, before the HG update) so he sent his injectors off for cleaning/testing. The shop is telling him he needs injectors, but the truck showed no signs of injector issues before he pulled them, and the reports actually look good other than one single parameter out of spec on just one injector:

Do any of you with injector knowledge/experience have an opinion? What is "TP2 Return Quantity" that seems to be really high. What does that indicate? At most wouldn't he just replace or rebuild that one injector?

Thanks,
TJ

If it's a genuine Bosch test bench, I'd trust it. I'd get a new one.

I would replace that one injector, not the whole set. The test shows a high return rate from that injector and it could cause issues with starting in the future.

Thanks guys!

Any thoughts on the best place to get an injector for a good price. I'm sure he'll want a real Bosch.
