Hey Scotty
Been working on my 4v6 Ford Ranger Edge 2005 with automatic transmission. Did not notice anything serious right until now. So, based on a gauge it takes a long time(10+ mins) for the truck to warm up(first start only). A lot of white smoke and condensation is coming out of the tailpipe. So, it gave me a suspicion that there is a coolant is mixed with combustion gases. Another thing I looked at was an oil filler cap. There was a white sludge under it. Pulled out a dipstick, and the oil is still clean. No funny smells from the exhaust pipe.
The truck wasn't serviced until I got it. Took the Ranger to the service. Truck had been sitting in a drive way for a long time before I got it, and, hence, there is rust. Changed oil, bled brakes, and serviced rear diff myself. Had an error code (P0442). Took the truck to a local mister fix-it, replaced the gas cap, and it seemed to work.
I use the truck as a weekend driver. So, here is my question. Is the truck having those symptoms cause I don't drive it too often or there may be an engine problem? Truck has a low mileage(around 90000 kms).
Well if it's getting a blowing head gasket eventually the engine will stop running. So do my video how to tell if your head gasket is blown Scotty. And if it is going you could try some head gasket sealer like bars and pray at last a while
