I have a 1980 1 ton dually 2WD pickup truck I purchased to pull my horse trailer. The truck is very clean, was originally a california truck. I noticed a little rough 'miss' every now and then when I first purchased it in the winter. I only use this truck occasionally- soley to tow. On my way to a horse show in June I overheated. Replaced water pump, raiator cap (radiator was pressure tested in jan- was fine) and thermostat. vehicle still overheated, only when towing. By this time engine has more miss/rough running times, coughing, spitting and sputtering intermittantly. Timing checked, it's fine.
Truck is running rich- can smell gas and let's not talk about what the mileage is. oh this is a 454 engine.
As of last week the truck is now running so rough I was unable to make it up a hill/driveway w/ trailer in tow (trailer is heavy- 9000 lbs) this is a 1 ton pickup-camper special. I have NO water in the oil/ or oil in the water. no black or white smoke. Am thinking it's a cracked head??? Help.
