Fuel Automotive & Accessories

They lack expertise with 6.4 Powerstroke and as a result aren't able to provide the best advice. Their moto is "diesel done right" however Doyle did not make it right when he failed to provide expert service on my truck. They are honest and will give you the best advice based on what they know. Unfortunately this resulted in me doing a head gasket job on a worn out engine. The lip on the cylinder should have resulted in them advising a whole new long block. I ended up throwing $8500 out the window only to have the engine start knocking less than 800 km down the road. This was 800 km on my 2000 km move. I hadn't even paid off the bill from Fuel when my engine was being replaced and my head gasket job being rendered useless. In addition, it was never recommended that I bench test my injectors. I was later told that this is essential since doing a major job like head gaskets, testing the injectors is a key quality step. As it turns out, 3 of my injectors we over fueling and needed to be replaced. The pictures show the cylinder wall scoring on the number 1 and 5 cylinders 2000 km after the head gasket job. The wrist pin was knocking on number 5, so it would not explain the scoring on number 1. The wrist pin failure was not their fault, however the wear and testing of the injectors (which would indicate over fueling and explain the burn pattern given the stock tune that I ran) should have resulted in a recommendation to replace with a long block. Perhaps Doyle is more knowledgeable with 6.0's and Cummings. Pictures of the head gasket showing failure between the water jackets are below. The head was fire-ringed and ARP head studs were also added. I don't feel that either of these were well advised considering the fact that the head still failed (just not into the cylinder) and almost immediately. All pictures were taken approximately 2300 km after the head gasket, fire ring and arp studs were installed.
