I bought the 186 kit from DH motors which came with a Morin oil cooler. Only problem is that the lines won’t bolt to the cylinder. I tightened them down with two copper washers and the lines are still loose. Seems pretty simple to connect so I don’t understand why I would be having this issue. I can thread the bolts in until they get tight by hand and the bent ends are on the cylinder like they should be. Any help would be great.

Wasn't that the cooler where the lines enter from the bottom?
I watched a video and it showed it being mounted upwards which wouldn’t matter to why they won’t bolt into the cylinder. Also now looking at DH Motors site for the kit it appears that my lines are different from the ones in the picture and a different mount.

I had the exact same BBK and I had to get a tap and extend the threads but there's a chance that the banjo bolt could thread into the head too far and restrict oil flow. Just use common sense and either extend the threads into the head or shave some of the banjo bolt down.
