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 |

I think your a little on the lean side still. I shoot for 13 to 13.5.

QUOTE(underthetire @ Jul 9 2011, 10:55 PM)  I think your a little on the lean side still. I shoot for 13 to 13.5. I need to adjust the MPS. Fuel pressure is maxed out. I have on with me for this purpose but I need a 7mm star wrench with a hole in the middle. Everything else is fine and the correct part number. Valves, timing, correct injectors, correct distributor etc . The MPS is not leaking and has not been worked on. But I feel pretty sure this is the culprit |
