[mkiv] Factory oil cooler alternatives

[John Cribb]

John, I've done something similar to what Oolan has suggested, although I
used a Mocal sandwich adaptor, and retained the OEM spin-on filter. The
Mocal sandwich adaptor incorporates a built in thermostat, so the oil stays
in the motor until its hot enough to require cooling. This helps avoid the
problem described by Bill.

First I removed the OEM oil cooler casting, plugged the water lines from the
block, then put the Mocal adaptor on (next to the block), then the OEM
filter went on top of the sandwich adaptor.

Then ran the oil lines from the Mocal adaptor to a large Long TruCool cooler
mounted in the driver's side brake duct.

It's been working fine for 4 years now (albeit I drive the car less than 500
miles per year).

I have some good pics of the install if you'd like them?

Do you want to remove the old oil cooler or leave it in place as an oil
warmer?  Water heats up faster than oil and the water to oil heat exchanger
will work in reverse for a time.

Put a spin-on adapter in place of the oil filter and set up a remote oil
filter.  Use -10AN or -12AN lines.  If you have an FMIC you can put the oil
cooler where the old SMIC was on the passenger side.  You also need to use
an oil thermostat so you don't over-cool the oil.  Don't forget that the oil
lines will cool off the oil a little and the oil lines will get hot.

I'm partial to Setrab coolers.
