thanks for that info. yep, ive now read that the sender must be fully submerged in oil to get an acurate reading. Also interesting to find some cars use oil temp senders for both before/after oil passes through the oil-cooler, to get 2 different readings!
Still unsure of where to mount it though, the GReddy sump plug replacement type seem the easiest, but that point is very low to the ground and i would hate to scrape it on anything...
the sandwhich plate option is about $50-60, so at that price its almost worth spending a bit more to get an oil cooler kit that has the adaptors anyway...
hmm, not sure..
