Ford 6.7 Powerstroke owners! Have you had your crank case filters changed? Recommended service interval is 50,000 miles. Over time oil residue will clog the crank case filter creating excessive pressure inside the engine and create oil leaks. Unfortunately for this truck the crank case pressure was so high the turbo resulted in failure leaking oil out the tail pipe. This truck has 88,000 miles on it and not covered under warranty.

6.0 F-350 came in with an oil leak coming from the top rear area of the engine. Upon further inspection we found an improper repair to the High pressure oil pump cover. We installed a new cover with all new gaskets and seals, the truck is now on its way and not leaking oil!

Meet Paul! He is our undercoating specialist. Today we did a quick demonstration on the back of this truck to show what we spray on the chassis/ undercarriage of your vehicles during these winter months. You can watch the salt drip from the truck. Followed up with a rinse then undercoat. Don’t feel like you have missed your undercoat window, we spray year round! NHOU
