[DeTomaso] DeTomaso Digest, Vol 46, Issue 9- Oil Cooler

[Julian Kift]

Bob,
 
It sounds like you've already experimented a lot, but most other people have had best success with the water-oil (laminova style) coolers, so the question is what is the underlying problem here?
 
What is your water temperature? My oil temp stays at a pretty constant 35 degrees above water temperature and I've heard similar deltas from others. a) Are you sure the readout you get from your oil temp gauge is a true temp? (I've seen mismatched senders and gauges i.e. a 280 degree sender rigged to 300 degree gauge, so full scale deflection when oil reaches 280 tells you 300 on the gauge!) b) is your oil temp sender in the oil pan or in the block? I've heard of 40 degree higher temps if its measuring in the block.
 
I'd be tempted to do a little more up front investigation and physically measure oil temp prior to spending more $$.
 
Tomas: Now that is a bright idea and as you say can be done using off the shelf dry sump parts.
