BB oil pan indentations - need info.
This post/question might be more relevant in the engine/drive train section but there seems to be more such traffic here and I need info quickly.
Am finishing a trans/clutch, new rear main seal and oil pump check on a 402 BB and am cleaning the oil pan before paint/install. I have never removed/inspected a BB pan before, so am uninformed. This one has some indentations and I don't know which ones may be factory design and which are PO dents that should be banged out. Does the normal BB pan have an indent (about 3") immediately next to the drain plug (on bottom of pan toward the center and running lengthwise) and is the shallower part of the pan supposed to have a small oblong indent crosswise - and past it a small round indent - both centered on the midline? Thanks for any quick insight.

Doug*** Thanks, I thought about that - need to get it completely clean first and will try to post a pic if that becomes necessary.

Re: BB oil pan indentations - need info.
That indent is for the oil filter clearance...

Re: BB oil pan indentations - need info.
Thanks a bunch weg921 - that is perfect. Your pic shows that the minor ones I already have removed were needed, and now I need to bang out the dent just adjacent to the drain hole. It is a rather sharp crease and not easy to get to due to an existing baffle, but think I can get some of it, at least. Thanks again for the quick help.

Re: BB oil pan indentations - need info.
Actually, the specific configuration of the bottom side of those two pictured BB pans is different - neither bottom is shaped exactly like mine (which I believe to be OE) - but both have the same important aspects showing that I need to press out one sharp dent. Thanks again.
