I had two threaded bungs welded into my Cobra alluminum oilpan. One is where I installed a Steff's 110V ac powered
oil heater for those really cold times when I really wanted to get the car out. The other bung is where my
oil temp bulb for my mechanical dash gauges is located. My concern is what temp the
oil resivoir was in the pan as that is what the oil pump is dealing with. Hy volume oil pump w/ slightly higher releif setting make for a load on distributor drive shaft with cold oil. I reguarly keep an eye on the oil temps. I must try keep engine revs to under 1,000 rpm until oil temp reach 140°. Too high a temp and I'd better start checking things like cooler obstruction, low oil quantity, or too much oil and foam. All thing compared to engine coolant temp and oil pressure, and ambiant air temperature. You'll know what is normal and when something is wrong. Or you could be like my old dentist . He'd say "let me know when it hurts" not that he'd stop doing what ever , just wanted to know.
