This morning I get an angry phone call from a customer, seems his truck is sitting at the ryegrass rest area dripping oil and blowing white smoke... Last September I replaced the head on this truck, it was pressurizing the cooling system something fierce. The machine shop said the head was junk, full of weird little stress cracks.
Anyway I go to look at the truck at the rest area. It's dripping oil from the exhaust joints and the blowby is unbeleiveable. Then I caught it... Resistors on the manifold pressure sensor plug and the fuel temp sensor plug. Those weren't there when I replaced the head, I'm betting hidden away while the head was being done and somebody forgot to hide them today?
Got it towed to the shop and have the resistors stashed in my tool box for the owner to see. Head's not off yet, but I'm sure it's a scored liner and piston.
