Thanks much Andydodge for your explanation on how to correctly mount the oil pan gasket, and Bryan for the pics......but still have questions here.
From another topic I have taken a pic where you can see how oil side pan gasket sides should be mounted, just as Andydodge explains, but from pic you can see there are no cut outs on the end of the side gaskets?......
From Bryan pics from his 1948 engine it looks as if the "4" rubber piece which inserts in the main bearing cap protrudes from the cap, if that was correct that will be the explanation for the end of side gaskets cutouts.
I think that when the "4" rubber protrudes from main bearing cap side gaskets should have a cut out (mine) and when "4" rubber ends flush from main bearing cap (mine), side gaskets should not have cutouts. It looks as if both were used over time. If that could be right I either have wrong the side gaskets or the wrong "4" rubbers,......mine is the PE 1934, 201 engine but which should be correct?.
Below a pic I found from a seller in ebay which offers an NOS oil pan gasket, he offers it as "1933-1957 oil pan gasket for Plymouth"......it has no cutouts.
I have also checked the "Plymouth passenger and commercial car master parts list" and can see that engines between 1933 and 1938 ( PC,PD,PE,......P7,P8) all use the same side gasket, 780477.....but was this the one with or w/o cutouts?......
Again thanks for any help that you can give me
