TylerB46 Posted April 10, 2018 Report Posted April 10, 2018 Hey guys, I’m putting new gaskets on my dodge 230 oil pan and it came with some o-rings that I’m supposed to use to make new main cap seals out of. I’m not entirely sure what that is, so any help would be great. Quote
johnsartain Posted June 27, 2018 Report Posted June 27, 2018 Underneath the front main cap are two groves that come out at an angle.The o-ring is just the size to fill those groves and act as an oil seal at the point where the cap meets the block. You would have to remove the front main cap to get to it. If you do not plan to remove the front main cap and are sure that the ones you have are not leaking, then you won't use it. Quote

Im not sure if the old ones leak or not, but the engines back in the truck now so I guess we’ll find out haha Quote

How can I tell if they do leak once the engine is running? I haven’t started the engine yet since the rebuild. Quote
johnsartain Posted June 27, 2018 Report Posted June 27, 2018 I guess thats the thing. If you take it apart, replace them, and re-torque the main cap Quote

Well I had to take the engine back apart and to a machine shop for other issues, and ive got all the caps off right now, but I don’t see any grooves in the front main seal, it’s totally flat on the bottom and where is goes on the engine. So do I still need to use that o ring? Quote
Dodgeb4ya Posted January 5, 2019 Report Posted January 5, 2019 The two grooves using the rubber 1" long are in the bottom of the aluminum oil plan to block seal plate... 2 Quote
