Oil pickup tube O ring I have read differant suggestions as to which O ring to use on the oil pickup tube for the LS motor....I recently bought a conversion pan kit from GM and the O ring was reddish in color and .174" thick.........others have mentioned that a blue O ring #12557752 that is .134" thick should be used......makes sense that a thicker O ring would give tighter seal.............thoughts anyone??
The thick one is for the pickup tubes that have a recessed area where the O-ring fits. They are not interchangeable, do not put the thicker O-ring on the pickup tube that does not have the recessed area or you can pinch or cut the O-ring.

Gotcha...........thanks..........what kind of investment was the HP tuner set up for your motor? The LS2 I have has the 58x reluctor, I have to send the PCM out for the initial tune but would like to be able to fine tune it myself in the event of future changes............
