So I just had a shop replace the oil cooler and install a Sinister EGR tube. The truck has 118000 miles on it. I have put about 200 miles on the truck since it came out of the shop. This weekend I took my toy hauler and went camping about 90 miles from my house. Before I left town the factory oil pressure gauge was working intermittently, I took it to the shop that did they work and they said it was a bad sensor and would order one up. The temps were within range (5-8 degrees difference) on my scan gauge. When towing 9,000 pounds the temps were within 12-15 degrees up some very long steep grades. I got to camp no problem, The next day I went to start the truck and it was really hard to start, ran very rough and was blowing grey smoke. I had to run to a event so I left the truck until about 6 hours later. This time the truck started up no problem so I turned it off and enjoyed the day. I went to head hime today(Sun) early am, the truck started up normally, I hooked up the toy hauler and just before heading out I did my usual walk around to make sure everything was in place. As I looked own at the truck I saw a puddle of oil on the ground, about 10 inches in diameter. I shut the truck off and could see oil leaking from the passenger side of the engine but I couldn't determine where the oil was coming from? I had the truck towed back to the shop and they will look at it in the morning, so any thoughts on what could have happened?
Thanks
