Hey guys, I now have 8000km's on my Amsoil Dual Gard bypass system I installed on my 09 Ford f350 with the 6.4 Powerstroke. After 3000Kms on the system it was brought to my attention that the stock orifice of .094" was too large for the capacity of the Powerstroke engine. Although I had good oil pressure and good flow through the filters I decided to use a .032 Orifice as was recommended by both Amsoil and others on this forum. I've now run another 5000kms on this system since changing out the stock .094" and installing the .032" orifice. I just took an oil sample and sent it to Blackstone labs with a total of 8000km's on the oil, but noticed the filters are cold on the bottom half. This indicates that the flow it too slow through the filters and needs to be increased ( what you get when you put a class 8 tractor filter on a small truck). I never had time to change out the orifice to a larger one (was thinking .050" this time) Question is, is it normal to have cold filters in the winter at -15C or should they be hot as well in winter and summer? I'm running Shell Rotella T 15/40 year round and had hot filters with the .094" disk intalled at -30C. We'll see what the Blackstone results are when I get them back, but thought I'd ask for input from you guys. If you haven't seen this system here's some pictures and a video.
