Title: Oil Filters/Coolers and full flow Post by: modnrod on December 12, 2015, 06:23:34 am On my roads doghouse filters leak every 10K or so, and are a PITA to change.
So, I have come up with "a cunning plan Baldrick". ;D Oh, and no, it's not new or original really. Instead of mounting the cooler so vibrations get it, I thought I would tap the oil cooler holes for 3/8NPT and screw in these....... (http://i1212.photobucket.com/albums/cc458/MODNROD/VW/oil%20cooler%20outlet%201_zpsqqogx5qt.jpg) (http://s1212.photobucket.com/user/MODNROD/media/VW/oil%20cooler%20outlet%201_zpsqqogx5qt.jpg.html) The I could also use all the airflow available by blocking off the doghouse slot (a bit like the Mex bugs have done, but completely). Cool! ::) Except after looking at the case there, I rekn that a 3/8 tap would weaken it a lot on the outlet hole, it would end up pretty thin I think. Has anyone had issues with cracking there after tapping the case for fitting? So then I thought I'd express my inner 70's-ness, and use one of these........

I've used these a few times in the good old days and never even thought of it. Then again, back then I rarely gave thought to anything! :D Oh, the full flow part is where I carefully jam a bolt under the oil control valve to make all the oil go through the cooler all the time, then use a thermostat on the filter head, it's a dual-relief case. |
