Yes you COULD make a loop, I'm just curious why you'd want to. Just get a short piece of 5/15" Ni-copp and bend it into a loop.

In all my internet searching a while back for gen 5 info, there are no experts, lol. I'll be home tomorrow and can look at my cooler line fittings.

I don't think he meant to say tranny. Just oil cooler.

The ports are made into a gen 5 block, no sandwich adapter.

Ok lol seemed odd but hey you never know.

Well first of all I'm no expert LOL but I do have a Gen 5 block with the oil cooler lines like yours I pulled my lines off and the adapter. It threads into a weld in bong that I have from work we use these on the back of pontoon tubes to put the plastic plug-in to hold air. It is a pipe thread as was said on the other post. We have a tap at work for it I can get you the size on Monday if you don't find it by then

I want to eliminate the oil cooler lines on front of the oil filter.i got rid of the horizontal assembly and put the adapter on for a vertical filter

 

[hiltijoe]

Stupid.i would have never built this black now known.but to late

 

[hiltijoe]

k bucket let me know.im getting ready to install it in the truck but have to resolve this issue first

Well, my fittings are MIA. But, a regular old pipe fitting did feel like it threaded in nice. I may have been completely wrong about them being metric o-ring fittings. I just don't remember.

In the pics it looks like it would be an inverted flare. I have an oil cooler of my 89 R3500 would they be the same fittings. If so I could pull the fittings to verify.. ok I got one out..so I guess they would be metric O-ring

I have the prob figured out 3/8 pipe thread.remove the oil bypass plug in the center of the filter done deal.now I got to figure the best way to remove the bypass valve

I finally found my fittings this morning, and sure enough they are pipe thread. The one that goes in the port to the rear has a goofy looking tip on it, like it engages something in the block.

So the bypass plug is up in where the filter screws on? I though I read it was in one of the cooler ports.

Ok, I got that bypass removed from my block. After unscrewing the filter stud, there was a lot of room in there. To get the bypass out, I tried to get fancy with a clutch pilot bearing remover. But it didn't fit, so I went very unfancy and threaded in a big lag bolt. That worked well to pull it out. It actually didn't even hurt it.
