I'm getting ready to to the Chrysler 318 engine back together and I noticed a slight difference in the aftermarket rear main bearing from the original. The original bearing has a second grove on it (see picture ). The aftermarket bearing has no second grove and appears to end there. None of the pictures I have seen online show a second grove so I'm wondering if it is necessary or even available?
Also, I'm trying to decide if I should replace the oil pump or not. Did these have a standard flow or high volume oil pump?
Thanks again for all of your help,
Dan B
