Gary,
I was thinking strongly about changing my Amsoil dual bypass over to a single bypass with a sandwich adaptor and I would like to route the filtered oil back to the the filler cap rather than back to the sandwich adaptor. I wonder if the return hole on the Perma Cool could be plugged and ignored? The Amsoil 80A mount has a restrictor (I read that here) and the Perma Cool Sandwich adaptor has a restrictor also, right? As I understand the system, one of those restrictors should be removed. Why do I want to change? For one thing I need the space so I can put in a Motor Guard transmission by pass filter, and also I am thinking about changing to one of Ralph's Motor Guard TP filters fir the engine oil after using up my last Amsoil bypass filter. One more thing, the current bypass filter location puts it right next to the distributor and I am having igntion cutout after driving for several hours in warmer weather, when the oil filter gets up to it's max temperature. Any ideas on how to insulate the filter from the distributor?
Thanks,
Neal
