The oil pump pick up tube o-ring looked to be in perfect shape and installed correctly. Just to be on the safe side I picked up two new o-rings from the dealer on the way to work this morning.
GM makes 3 different sized o-rings. My online reading has shown that all of the oil pumps are the same size but that the pick up tube itself has different sizes and you match the o-ring to the pick up.
Stolen from a 2009 Ls1tech.com post:
The green I believe is even thicker than the red design but can't find those specs right now.
My Autokraft pan came with the blue o-ring but I bought both a blue and red o-ring today at the dealer. The fit with the blue o-ring that came with my pan just doesn't feel that snug when playing around with it this weekend. So tonight I will try both the red and blue o-ring. My online research showed some folks and shops/dealers using the red o-ring even in fbody/corvette applications with better success rates.
