I am driving from Chicago to Reno today. I did 22 hours in the seat and I have 700 miles to go!
I am having some cooling issues. I feel I am running hotter than I used to. I did have a lean running condition and I think I am out of the woods on this one. I installed an AFM meter. I had to boost the fuel pressure to get to 13.9 to 14.4. The other thing I did was I used Brad Penn 20 W 50 oil. I was running Royal Purple 10 w 40. I used the Brad Penn because it was available and this oil is supposed to be the oil to use (but maybe not the viscosity) Could this be causing a heating problem? I think an external oil cooler may be in my future. FWIW, I was near the red in the early morning cool hours pushing 70. Once I got to west Nebraska and Wyoming, the heat became a real issue. I plan on Being in Reno for more than a week, anyone want to connect up. drop a pm. I would love to hear form anyone here |

Sounds lean...
Brad Penn dies typically run hotter, it has poor thermal conductivity.. That was the main reason that I pushed to finish our snake oil in 2009. But remember, hot oil is just that- it's not engine temperature. How hot are your cylinder heads?? Hot oil doesn't crack heads or drop valves~ |
