My truck had a bad rod bearing and 166k miles, so instead of just going through the lower end I decided to get a rebuilt engine. Anyway after all is said and done, the truck is running smooth but seems a little lacking in power. I drove it for a few weeks like that and noticed that my mileage dropped significantly. I was getting 15-16 MPG hwy with my old engine and now only 9 MPG hwy with the new engine. Not to mention I just pulled my first trailer with this engine, a small utility trailer, approx 300 lbs, with a sportsman 500 4-wheeler on it, approx 700 lbs, and it felt like I was dragging a semi behind me! The truck would barely creep up to 65 mph and it was alll it could do to stay there
I know the quality of the engine is good, my family ownes the business, however I installed the engine, I own a body shop, I'm not much of a mechanic
My question is, I've been told that there are two timing marks on these engines, 95' Ram 5.9, is it possible that I have it timed with the wrong one? so that ignition happens just passed TDC? My timing light shows I'm on time for one mark, but not the other. My truck is going to my uncles shop this Thursday to get it figured out, I'm just wondering if that could be the case. Thanks!
