oil cooler on all m20?

[///M42 sport]

I noticed on bmwfans that there s a hollow bolt available that goes where the oil cooler lines bolt in. Just wondering if all m20s had oil coolers.

Nope, not all M20 engined cars had an oil cooler.

M20B25 cars came with coolers.

anyone running without coolers have issues?

In most cases one will not run into oil temperature issues w/o an oil cooler. I've run my Spec E30 (which has data logging) with and without an oil cooler (bigger than stock and in a better location) and haven't seen excessive oil temperatures. What I have seen is a rise in engine temperature and lower hot idle oil pressures.

The most common failures in cars equipped with oil coolers are leaks in the hoses. The economical fix for that is to have the hoses rebuilt at a shop that does hydraulic hoses.

meh, I think I'm going to delete the oil cooler. Its a daily only anyways.

Who knows what has been done in the past 24 years maybe they removed it or maybe I have a eta bottom end should I try to source another one? Or not bother

you can get a $8 piece to replace the oil cooler housing with the lines. We stock them :)
