On the issue of getting heat to engine oil:
We looked at two ways of doing this. One was more
expensive than the other so you have to choose which
you have more of, money or time. The expensive way is
to buy or make a canister to enclose a heat exchanger
that connects to you engine oil supply. To each end of
the canister you weld a hose barb to connect your
engine water supply. When engine temp comes up, so
does the engine oil. The cheap way (the way we did it
on the lakester) was to buy 1/4" aluminum air
conditioning tubing from the hardware store, coil it
so it fits in the engine oil dry sump tank and attach
both ends to two brass hose barb fittings mounted on
top of the tank. Attach hoses to these brass hose
barbs and run them to the engine coolant system. This
system puts heat into the oil and brings engine oil
temp up along with engine coolant. The best part is,
you use the coolant thermostat to regulate both engine
and oil temp. Both stay very close to each other even
when racing.
