one other thing I noticed on your vids, the newly welded pipe fitting you installed into you oil pan, what type of threads are on the fitting & on the "B" nut AN hose fitting (the blue one) does that have an angle seating area, like a 37 degree flare?
Just wondering.
Also, what RPM does the factory say to have the engine idle at? 650-700 RPM? I can remember, it's been too long.
