External oil cooler kit? Options

Is this kit compatible with the type 4 filter? Seems like pretty easy add on?

I would prefer a coupling that didn't use the external filter until 180f but can't find a complete kit.

Here is what happens to an engine that has been run too cold with excessive condensation causing rust up in the oil breather.





As always, it’s your car and your decision what to do based on personal opinion. Bear in mind that physics doesn’t care, and there are consequences to not running oil hot enough to drive out the condensation.

Fact or opinion? How do you verify that to be the cause?


A little different take from the Bob Is The Oil Guy forum.

That engine when torn down was run without cooling flaps and with a cobbled deflector to the oil cooler. This caused the engine and oil to have extended warm up and to run cooler than it was designed to run. I don’t know the drive cycles it was subject to. However, if this was run infrequently and run on short trips, that would only make matters worse. Based on the amount of rust and sludge that was in the sump, and the condition of the breather, I’d guess lots of short trips.

For those old enough to recall the 80’s, removal of cooling flaps was a “fix” applied to many 914’s that were thought to be running hot by well meaning but misguided folks that tried to make air cooled engines run at the same oil temps as water pumpers.

Removal of cooling flaps not only results in delayed initial warm up, but overheating at high load because the oil cooler airflow is practically non-existent.

When some finally realized that these engines are actually air AND oil cooled, they got even more creative (in the case of this engine) and removed the flaps but made a deflector to force air to get the cooler at all times - presumably to avoid the aforementioned tendency to overheat under high load.

The 80s and 90s generally were not kind to 914’s. Lots of these cars end up in the hands of people that didn’t understand air cooling and whom were too broke to maintain them properly. They were considered cheap and disposable.
