2000, 3.0 Flex I had water gushing out of the radiator a few months ago so I parked the truck in hopes of selling it as is. After fielding numerous idiot offers of $500.00 I decide to fix it myself. Over last weekend I pulled both heads off, head gaskets don't appear to be blown but that does rule out warped heads. What I found odd was the last piston back on the driver's side appears as if it's brand new, problem is we've owned the truck 4 years now. Anyone ever seen something this clean after running for the past 4 years? I'm dinking around with replacing the whole engine as the truck has nearly 250K on it and rear main is leaking.
