Thanks. Excellent video. I have a better understanding of the theory of operation of these diesels now.

Hey man, appreciate the video and thorough procedure documenting. I'm failing to build pressure have extended crank to start like over 30 seconds. Once it's idling desired ICP PSI is 800 but I'm only getting 480 to 500. Clearly there's a leak somewhere. IPR air test reveals no leaks. ICP air test with IPR blocked by a ball valve on the IPR test fitting reveals no leaks until after about 5 minutes when gurgling and air can be heard through a listening device when placed inside of the oil filter housing. I've read that the only time you'll hear air or oil gurgling at the oil filter housing is when you have an internal leak within the hpop. I pulled the h pop and bench tested it only to find zero leaks whatsoever. Anybody have ideas on what could be going on here?

So I cranked up my air compressor to 125 which is the max and bench tested the hpop again. It took a minute or two but now I can put a heater hose to the low pressure intake port on the h pop and hear gurgling. Sometimes it takes a while for the leak to reveal itself. Another tech told me that these systems are designed to run at thousands of psi and when you're only putting 125 into it it may take a while to hear the leak.

Great video bud

Should the injectors each (all) leak a small amount of air?

Hey man I have no cam sync. Replaced cam sensor with motorcraft still no sync. Other numbers good. Any ideas?
