FordTechOne,
Oil Condition. I checked the oil level and it was low. It was right at bottom hole on stick. I checked under the truck to see if I could detect any leaks. A lot of oil on underside of truck. Looks similar to the condition that it was in when I had received it post initial warranty procedure. What I thought was likely a sloppy oil change may in fact be a leak. This truck is a mess...Note that this was reported to the dealer after cam phaser procedure and they cleaned the underside of the truck on follow up appointment. Full transparency, I don't remember how good of a job they actually did of cleaning the underside of the truck. However, to me this looks active and not residual.
I changed the oil since I need to use the truck. I understand that by changing the oil, I'm tampering with what could be a valuable source of information. However, I don't think this whole dog and pony act is going to get to that level of sophistication (i did, however, save and bag the filter and contents). I could not find an obvious leak, but I'm going to look around after work today to see what I can find. In the meantime, please suggest potential leak sources in way of a cam phaser replacement procedure. I'll look around the front cover area and also anywhere else that I see oil. Another thought, could my PCV system be so out of whack that the truck is not venting correctly and some engine seal or another has been compromised? Who knows. If you have knowledge or what engine seal is most likely to blow in that case, please let me know. Will report what I find when I look around.
PCV System. I did some poking around in the engine bay to inspect PCV hoses. I didn't find anything amiss on initial inspection, but I only checked for proper connection and also inspected the o-rings for each tube. I felt along the body of the tubes, but did not REALLY give a close look for cracks etc. I plan to take another look with emphasis on the tube structures. The PCV valve on pass valve cover looks normal/clean on exterior. The sensor pigtail seems to be properly connected, but there is a little bit of play where the sensor penetrates the tube. This may be normal.
While inspecting PCV tubes, I found an issue with the intake installation and I'm betting it is not the only issue with the intake install. If you follow the main intake tube from the airbox, it branches downward and eventually connects to the driver turbo. If you follow the tube downward toward the turbo, you will find a mounting/locating bracket with two rubber grommets which mate up with posts on the intake tubing. This locating post was not inserted into the mounting bracket grommet, it was underneath it. This caused the tube assembly to sag and also caused the drive turbo boot to bind and restrict. I went ahead and fixed this. Intake tube to driver turbo connection much straighter now. I felt like this was going to cure the hissing sound for sure, but it did not.
I'm going to carve out some time to inspect all intake system and connections soon. I have a hunch that I will find something else wrong and likely the source of the hissing sound that I get under load. Someone looked at this truck twice with the intent of clearing a hissing sound from the engine bay and did not see this. If somebody missed this on two different service appointments, all bets are off and everything needs to be checked.
I have not messed with PCM/code clearing at this point, but I may elect to clear codes and CEL and see what happens. I don't think it could hurt anything at this point, but I'm doubtful it will glean any information that will help with troubleshooting.
As for the previous owner and the trucks services history, I did get hung up on this when shopping the truck. There was no proof of routine maintenance within first ownership. I recognized the risk and took it. If all of this ties back to that decision, then I own it. Period. Entirely possible this truck went 13k on delivery oil. Ford would never know unless they analyzed the oil as part of the certified pre-owned inspection, but that isn't the case I'm sure. Anyhow, oil is lifeblood and cannot be overstated.
I've got some more inspecting to do. I will report back what I find. Please offer as much pertinent input as you can with the information you have. I'll take any clues that I can get to get this right myself. I appreciate your continued assistance and input.
Thanks
