I've been told that i need to "know" my oil temps and that merely lowering temps by installing a dual cooler setup wouldn't be enough, but i have to "know" exactly how much cooler they are going to be. Yeah. So...what's the best/easiest way to do this? I'm pretty mechanically inclined and like to do as much of my own work as possible, but i'm still not looking forward to what's going to be necessary to do this. Might as well shoot me now...

Thanks.

My apologies. I usually don't do that, but mitigating circumstances dictated that i just post the question rather than spend another hour searching. If it were all up to me i'd spend the time, but then my wife get rather, err...irritable. Thank you for taking two minutes to save my marriage.

 

I have a writeup on http://www.clubrx.org, which is currently down (grrr, fixin' to move web hosts soon!).

Basically, the rear oil cooler line attaches to the oil filter pedastal with a 21 or 23mm (can't remember) banjo bolt. Remove the bolt, put it in a vice, and drill/tap the head of the bolt for 1/8" NPT. Reinstall the bolt, screw the temp sender into the new hole in the bolt, done deal. VERY simple, clean, elegant. Only downside is you get the "coldest" oil temp of oil after it left the oil cooler on its way into the engine. But, it's MUCH better IMHO than using the oil drain plug and having the sender and wire get in the way every time you do an oil change.

Dale, I'll continue to disagree with you on this particular issue. The banjo bolt does NOT work for some gauge sensors, including the Defi sensor.

Despite the cons of the oil filter block adapter, I went back to it after the banjo bolt location didn't work. The block adapter makes for such a clean install and you get very accurate pressure and temp readings.

 

The banjo bolt idea seems like a good last resort option. But the replacement pedestal seems to be an even cleaner and better integrated option. Thanks for the reply though, Dale.

In case anyone else is interested, i emailed MRC MFG and they said they were planning on doing another run of the replacement pedestals in mid-Feb. I'll keep you posted...
