'O' ring Question
 

Hi Guys

I have one of your Chrysler engines in my 1960 Jensen CV8. Its a 383cu. I have striped it down rebuilt it and now have an O ring that I cannot account for.Other than it was in the oil pump tray used for keeping items together. As its more than likely for an oil seal somewhere I feel its quite important I find from whence it came. Can you help. Its 1 1/2" O/D x 1/8th.
thanks.
Regards
Pete.

That sounds like an oil pump pick up tube O-ring.
You just have to pull the pan and then pull out the oil pump pick up tube to replace it.
