So thats where you need to know the temp of the oil.As this oil is then STARTING its journey around the engine.Look at any wet sumped race/rally car,the temp sender is always in the sump.That sandwich plate is only for people who dont want to job proper,ie remove sump/drill and tap hole,fit sender and then refit sump.Best regards,Micky
I have no expereince with race/rally cars, but when this has come up on here before everyone seems to say that the sump is the wrong place to fit it, i know that everyone is not always right (myself included) but to me it makes sense.
Surely it's the operating temp that you want to know (ie: as it comes out the block), because you base your oil choice on how hot it will run, if you are going by the sump temp then you could choose a oil with a much lower temp rating than what it's actually getting up to as it goes through the engine and will be to thin giving you low oil pressure.
For me at least, i want to know the MAXIMUM temp my oil is at, not a cooler sump temp.
This is just my opinion of course!
