Yet another oil leak
I have a 2001 F350 CC 7.3 PSD. The truck has just over 40K miles on it and runs fine.
I recently had an Edge Juice and Attitude installed for use when I am hauling my camper. I never run it above setting number 3.
I noticed an oil leak that had started prior to installing the above items. About a 2" stain overnight. The place where I have my oil changed said "...rear main seal" but I doubt that.
Took it to the stealership that I bought it from and they complained about the chip. They kept asking me what boost I was running at. I told them to take it around the block and look at the handy digital gauge on the dash. They reported back "21 while driving" and I told them they were full of crap. I went and picked it up and watched the gauge which was reading anywhere from 2 to 4 under normal driving. I suspect what they saw was "2.1" on the display.
Anyway, they said that they couldn't determine what was leaking but told me that they didn't believe it was the HPOP o-rings. I don't know if I should believe them given their dismal understanding of the chip and boost reading.
Any suggestions on a good diesel mechanic in the Portland, Oregon area that would know what to look for?
Thanks, and sorry for the long post.
