Ranger’s hypothesis is a wild combination of:
- the Factory3 oil pan protector blocks air flow around the pan (not impedes or minimizes, but effectively blocks cooling air flow)
- the stock oil pan is almost as effective at cooling oil as the oil cooler that BMW installed on roughly 1 million M20B25s
Therefore, we need an oil pan protector with holes in it.:blink:
In considering a redesign of the pan (assuming Levie’s language re: attachment points) it would not take a protector much more robust than the Factory3 plate to have the weak point then become the radiator support sheetmetal. You will hit a curb, the pan won’t bend, but the sheetmetal will. Then we will be back here with another rule change.
For Christ sake, just take some brake duct hose and point it at the frigging oil pan and leave the F3P plate in place. I promise not to protest you, Ranger.;)[/quote]
Nothing is sure but death and taxes. But I’ve a fair amount of data on oil temps under different conditions and the results do seem to point to those wild combinations.
The real question is…Are we comfortable that the OEM oil cooler has more advantages (cooler oil) then disadvantages (another thing to fail, some reduction in oil pressure)? My answer to that is I don’t know. But I’m going to try going without it and see what the data shows.
Certainly allowing more air flow to the oil pan will make it run cooler. How much cooler remains to be seen. My data is interesting, but falls short of rigorous.
If the project doesn’t interest folks, then they can choose not to do it and go back to watching tv and downloading porn.
