6.4 and bypass oil filters
just a heads up, to a problem I encountered when I installed my bypass system on my truck. Went with the AmsOil parts, so before ya ask if it was done right, it's done the way everyone else would do it. The problem I encountered was excessive oil in my intake system. Did some looking and it was coming from the CCV. What it boils down to and what a few other people i have talked to have agreed with me on is this. when the oil returning to the engine from the bypass filter is coming in through the oil fill, as you know it's also the CCV can and the CCV air flowing out of the engine is hitting the oil and blowing it out into the intake tract.
I was noticing white puffs of smoke on start up after long drives. Figured it was oil coming from somewhere. My truck has 100,XXX miles, it shouldn't be an issue of being worn out. I drive my truck nicely. Thats when I checked the turbos. They were fine. Then I moved to the intake system, took the lower boot off the intercooler and a little less than a quart of oil drained out of the intercooler.
So just something to look out for. I plan on re-installing the bypass setup once I figure out a better way to run the return line from the bypass filters.
