oil temp sensor location
 

I have an oil temp gauge coming, and have been pondering/searching about where to put the sensor. Looks like the options are:

-get an oil filter sandwich plate (I have a 1.8L oil/water cooler/warmer waiting to go on as well, any issues?)
-get an adapter fitting for the oil drain plug (potential for busting off due to low clearance)
-drill/tap pan (no thanks)
-tee off pressure sender (not ideal for getting temp readings, I presume)

Any other ideas? Am I missing something? I have to buy a fitting/adapter/plate no matter what, so what is the preferred method?

I have mine in the drain plug. My car sits pretty low and I havent had any issues. The sensor still sits higher the the subframe bace.

I'd go with the sandwich plate in prep for an oil cooler in the future if needed. That's the easiest way to go IMO and though the temps will be cooler than the max temp the engine sees, you'll have a reference point. Didn't you drill/tap for the oil return on the turbo? That's what I did for more than one of my race cars. That's ideal IFYAM.

I have my oil temp sensor installed using a drain bolt adapter. I think I paid like $15 for the adapter from Greddy a while back. The cheapest way would be to drill/tap the oil pan. People don't have any problems drilling/tapping for the oil return line so I dont think tapping for a temp sensor would be a problem.

Drill and Tap the pan. If you need to know your oil temp, then you need to have the most correct reading.

Thanks for the opinions. I think I'll pick up one of the $7 drain plug adapters until I grow the balls to drill my pan again. I'm only putting the gauge in because I got a DDM works panel, and need to fill the third gauge hole ;) I'm not too concerned about the actual oil temps, actually

Why not a clock then.

Mine is in line with the old feed for the turbo

Sadly, they don't make an Autometer Sport Comp clock :( It was my first choice :cool:

I'll help you do the oil pan drill and tap man. It's really no biggie, even though it is a little bit scary.

My sender is mounted by the oil filter on the thompson relocation kit. Have oil pressure sender there too.

Watching oil temp vs coolant temp while driving is pretty interesting to me.

Should have added "...in 2 1/16"..."
