What is this? + Oil temp sensor location

[Dino86]

I guess that's the best option since the other one doesn't even have oil behind it...

I'm affraid I ran my engine oil to hot this weekend.
I installed sumpguard (alloy) so now there is no cooling on the sump from underneath (cooling wind)
Anyone nows the effect on the oil temperature with a sumpguard installed. I drove sporty, but not pushing hard (no track, no race)? Oilcooler is standard.
Engine consumed almost 1l over +-600km. Normally it's much less

Does high oil temp (= high temp. on bearings etc..) kill the Engine directly or over longer time only...
Hope the E/G is not F*cked
I didn't hear or feel anything strange...
