Mocal oil cooler & sandwitch plate ordered

Thermostatic valve to open and close the oil cooler seems like the best idea. When the oil gets too hot, the oilcooler valve opens and reroutes oil through the cooling element. You are right to assume that its not being filtered when this happens (no way to prevent that really, its a characteristic of almost all systems). As soon as oil temps drop, the valve closes and the oil runs normally through the filter again.

The water cooled system from the MR2 (the tube is a heat exchanger) is pretty nifty too. Water heats up quicker then oil so it helps get things up to temp. Max temp of water is 100degrees so it does help a bit with the cooling when things get hot. Probably not that much though. Would be a nice addition to any car if the pipe can be plumbed in easily into the AE86.
Don't see it fitting in easily though.

If the watter temp helps to stay on temparature, the cool water will help the oil getting hot, the oil Will still (also during cold days be hotter then 60 dgs even if it is running trought the oil cooler. and for driving.. that will be enough to provide extra damage to the engine (bearings and so..)

( I spoke to a guy who is doing sevice at a dutch rally team.. and they start driving at 60 DGS )
During Winter I can Close the opening for the oil cooler with an plate or so.. or better Isolate the oil cooler.
and even a bit of the opening of the radiator for the watter temp if needed..

But I dont think I will drive that mutch in winter season... and the dutch winters are not that cold.

I would like the oil to always be filtered.. cause I think that in case of a termostat in the sandwitch plate, It is open for most of the time..
and "dirty oil" gets in the cooler and will stay there.. or will go back in to the engine..

My Reno 5GTTurbo had the same system in the radiator, worked perfect untill i started to make some real power.
Then i bought an Mocal cooler with an thermostat in the sandwitchplate, it was always filtering

I know that oil and water channels run next to each other, I refresched the engine coolant system last saturday, But no progress in the temerature, I know that old bad coolant will not take that mutch heat then new coolant..

The engine (I guess) will make power when driving at 120 kmh.. 4000rpm
Indeed, during driving 50-80 kmh, the oil is not getting too hot.. but still 100 dgs during this the RPM is almost always below the 4000..

I will look for the mocal oil cooler!! quik search shows that this is indeed used for Opels..
