Hey Lou,
My car does not use the stock oil cooler anymore
It was bypassed directly to a vertical remote filter location before I bought it
I've heard good & bad about the Filter 1 type filter elements also.
Granted the metal filter micron size is larger than that normally associated with a paper filter, and it would take a whole lot of oil filter changes to pay for the higher cost of the Filter 1, but I do like the ability to tear down & inspect a filter without having to cut open / destroy an otherwise good filter can
My main / thrust bearings failed just recently when I was using the regular type oil filter. I put the Filter 1 on during the re-install so I have no other experience / opinion on the system as of yet
If my engine fails again
( ), then I'll just start all over,
blame it on Harold D ), and try, try, try again
My recent tear down and re-assembly (done at home - on my back) had nothing to do with my opinion of your expertise in GN engines Lou. I don't call you to try to bleed you for free advice. You have always offered advice at those times that I did call or saw you at the track, but you run a Business and I don't expect you to correct my problems for free. When I grow up I hope to know half as much about these Black Bitches as you do, and until that time it will be trial by fire and a whole lot of research
Later
Ray
