If and when anyone has the courage to clean the oil screen, do not believe the manuals torque numbers! 87 inch pounds is bulls@#t. Its more like 30 inch pounds, and the threads still stripped a bit. i have just cleaned the screen for the 3rd time and i wont be doing it again as there was very minimal "worms" on it. What a nightmare! i spent a lot of time easing this thing back together today. Be careful and read all the articles in here about this screen.
