Last night I removed the oil cooler/warmer from the VW oil filter assembly thing (not mine, but the image below).
I think I may be able to reuse the bolt that held it on as an extension tube. I am thinking I will cut off the inner tube, and weld an M20 nut, or a cut up an oil filter (for the female threads) to the end of it. That should create the extension that I need. We will see. Its cold out and the motivation isn't all there, thus no actual pictures.
