I am not sure why it leaked SO (1-2 qts) much during a 300 mile hwy trip and now it does not seem to leak at all.
The HPOP is constantly changing PSI to the injectors. Think of all the variables that could change the rate of "leak" like heat under hood, pulling a load, even being cold. I would push ALL my chips in the kiddy on this one. Sounds like your quick with the wrench, why not try one of the dye kits like advance or autozone have. Seems there not that expensive and you could see even a small leak. Or do what I did, clean the engine squeaky clean, drive the sh!$ out of it for a mile or two, look for the "starting point" of the oil on the engine. If it's right there under the HPOP, and your sure it's not fuel..BAM baby, your golden nothin else there (save the pump) would leak.
Oh yea, I'm not sure if you've seen one of these trucks with a HPOP leak, but to give you an idea of the quantity of oil that can be expelled, my tailgate looked like spatterware with black oil spots, the entire undercarage has been soaked with oil (great for rust prevention
) and I believe the truck was so low on oil, it was about to stop running. Over 5 quarts low... all in about 15 miles!
