Hey guys I've been talking to a guy about nozzles. He owns a state of the art rebuilding facility.
He sources his parts from Italy (not the same conterfit ones on ebay).
Anyway he says the metallurgy is the same or better than the Bosch German nozzles. He went on to explain in great depth about them. The pintle is matched to the body as far as fit, hardness....ect Said they are a 200k-300k mile nozzle.
With much higher technology and much better machines the nozzles are "world class". When our 6.5 engines were designed back in the 1950s 60s tech, metallugy and machines tolerence were not as good so they had to design a return fuel system.
He also said with todays injectors there should be very little to no return of fuel leaving the injector if it was built right, that if there is 1/2 oz or more per minute return fuel per injector then the injector is bad. If you have fuel returning from injector it makes the IP work harder to overcome.
He went on to tell me about testing proceedures and he got way over my head real fast.
He told be the traditional "pop test" using a hydraulic pump is not authorized anylonger by bocsh or most OEMs and that its a very crude test as it test only one thing. When they test they have state of the art machine and electronics to monitor all aspects like Leak back, return fuel amounts, duty cycle, number of time per second injector can pop....ect
They have 3 year unlimited mileage warranty on complete injector and no warranty on just loose nozzles. They say if they did not built it they won't warranty it.
The big problem I see is the cost of a high quality injector now days. To get their complete injector is $75 ea + core and just a nozzle is $44ea.
On the CKO counterfit Ebay nozzles for $62 per set! with free shipping!! They advertize those as being from Italy, BUT they are counterfit IMO. They make a very poor casting in Italy then ship them to China for machine work. These nozzles cost me $3 each (if I wanted to buy them) This raises the question, What do you get for a $3 dollar nozzle? Answer is junk! The pintle and nozzle is soft and wear extremely fast giving you a bad spray pattern, leaking, smokey wore out POS in short time. Again a $3 nozzle! Come on!!
Anyway just wanted to open a discussion about it.
