You don't say but I'll assume you have a Jetta or Tico engine in a Vanagon. Which is it? If you did a home made conversion, do you have the oil to water heat exchanger? This is located between the filter and the filter mount. The first thing you should do is determine how hot the oil is getting. An infrared thermometer aimed at the oil filter or oil pan after a long drive will give you a good idea. Ideally, the oil temp should be close to the coolant temp. If the oil is over 230F, there is cause for some concern. Over 250F, you can be in trouble.

If you don't have the factory oil cooler, add it. This is the cheapest option. If you do have it, find a way to feed it cool water from the radiator return instead of the hot water from the heater loop.

Any sandwich adapter that attaches to the stock filter nipple will use the OEM filter. The OEM filter is the same thread as the Ford.

As for an external cooler, my preference is a 19 plate Racimax or Earls located up front placed between the AC Condenser and front grill. Hose should be used at the cooler itself and to connect to the engine and 5/8 refrigeration tubing for the bulk of the trip. The oil Thermostat needs to be close to the engine or if possible, part of the sandwich adapter. My hose of choice is the Aeroquip Push Lock. Inexpensive, easy to work with, and good to over 300 PSI at 300F.

I'm thinking about adding an oil cooler. I have an empty spot on the passenger side air intake. I'm thinking about mounting it around or in the air intake cavity to keep the hoses as short as possible,and for air flow. Has anyone gone the route of an aftermarket oil cooler? What about still using the MANN filters which VW engines seem to need, the ones I found use a Ford filter.My Jetta filter, due to the 50 degree mount, is sitting sideways on the motor, I feel the pressure spring is vital.Would I be better off going with a remote mount for the filter to make it sit better, when using the Ford filter, with the Ford filter mounted on the firewall, would this take care of the pressure spring that is needed?

The reason for all of this is . I have 75-85- psi when cold. 25-20 psi going down the road when fully warmed up. Then I have 8-12 psi at idle when at the red light.I have a cheap gauge

Wouldn't cooled oil be better for the motor, with the air on, full of camper gear, going down the interstate trying to keep up?

I hate to keep spending money on this thing, but I do believe in P.M. maint. but it seems the P.M. is turning into Paranoid Maint.
