Hey folks...
it's been quite a while since i've posted on here...though have been back from time to time looking around.
that being said, i'm now working on my bug after almost 10 years of sitting...waiting for kids to grow up a bit and get my garage built.
i have a DTM conversion for my type 4. I'm running an external oil filter mount with an external Derale oil cooler. My question is which port on the oil cooler adapter should i be feeding my filtered/cooled oil back into?
Oil pump -> Oil filter -> oil cooler -> engine oil cooler adaptor....but which port?
my adapter is similar to this one : https://www.csp-shop.com/en/offers/oil- ... 4230a.html
thank you.

Re: oil cooler adapter port question
Heyman, welcome back!
Looks like you just need to eyeball the ports on that thing and follow the flow.
Oil comes out from the pump and it’s passage,
Then back into the case and main oil galley.
You’re going to want to duplicate the original flow just with a different route around.
Looking at the old factory filter adaptor will show direction.
Oil flows into the filter can on the outside of the element,
And out of the can thru the middle.
Hope this helps.
Got any pics of this thing?
Been wanting to see it forever!

Re: oil cooler adapter port question
hey...thanks for the input. I was able to find the answer in Jake's archived forum. basically I have a DTM V2 and am full flowing to a filter and setrab cooler.
the feed to the engine goes through the top port of the oil cooler adapter.
Not sure how/where to post pictures. i think i'll upload to TS and link here maybe? not sure if that's allowed...
thanks for the input though.

Re: oil cooler adapter port question
Ok...did more looking and even tried chatgpt...
i'm confused as it now seems the bottom port is the direct feed into the case bearings.
here's a picture of my adapter.

i also messaged Pile directly too see if he could help me.
thanks.

Re: oil cooler adapter port question
just wanted to give an up and potentially close this question for full flowing type 4 engine.
After researching/searching, talking with Pile (thank you by the way!), and looking at a bare 914 case, i've come to the following conclusion for my current setup:

i should have just fed the engine from this port, this will utilize the stock pressure relief and still feed the mains:

but...because of my setup and that my engine is already assembled and broken in, i'm using the bottom port of the oil cooler adapter now (pic above is wrong and i've since moved it). I wasn't sure if this was correct (long term) as the engine was successfully broken in using the bottom port. This will also
still somewhat have the oil relief in play, but I think it should be ok as the other ports on the adapter and galleys are plugged.

If the "engineered leak" is an issue, i'll try to replace the relief valve to something like this to further restrict "leak".

not sure if this helps anyone, but posting just in case

Thanks again Pile!
Aloha all.
