One more thing. Could I have a faulty oil pump? Forcing my oil out the filter area?

Hey I just wanted to say that my earlier post was referring to the 90°adapter. Sorry for any confusion about the normal oil filter plate. My apologies and I don't want to Send someone in the wrong direction. Just wanted to post what I experienced!

Do any of yall having these problems own a factory service manual? I prefer print, but they are available on the site as a free download.

Put an oil pressure gauge on the engine. It ought to peak out at around 55 or 72 psi, + or -, depending on the pump's relief spring.

does the factory service manual give a torque spec for the plate screw or the 90* filter mount bolt?

I had a massive leak from the stock-type plate, possibly because I drilled extra holes in it for more flow and somehow didn't do it right. Tried new gaskets, making sure the block mating surface was clean, torquing the bolt properly etc. and it still gushed oil as soon as pressure built up. So I threw it in the scrap pile and bought a Canton Racing billet aluminum oil filter plate with the O-ring seal. Just had to make sure the mating surface on the block was perfectly clean and smooth and it works like a charm. I've had it about 8 years now on 2 different engines and it still seals perfectly. Nice thing too you can easily replace the O-ring if it wears out.
Here's a link to the plate I have: 22-575 Filter Plate For Small Block Mopar Billet Aluminum

the oil comes thru the block in to the area behind the plate - where the gasket is - thru the holes into the filter. more holes = more flow into filter = less load on gasket. how could anyone drill a few extra holes in a plate and increase backpressure?

Yes... since the flow area of the original 4 holes is larger than the flow area of the ID of the center bolt, more holes is not going to change anything of significance on the plate loading.

In my case I don't think it was a pressure issue I think I somehow distorted the plate when I drilled it. It was very crude I just used a hand drill on a wood bench, probably pushed too hard or something.
I'm not sure, but to me, that's not the most important thing. The most important thing is the gasket order. Any idiot can figure out "oops that's too tight" before they tear a gasket. .......or if they cannot, find a new hobby.

is the area of the i d of the center screw larger than 4 holes? did mopar use some with more than 4 holes for the hell of it? this thread is about the plate which uses 1 gasket - no manual needed to figure gasket order!

Cuz he probably drilled them along the gasket/rubber seal line area of the filter

Could be, I usually use a drill press and step up size up as I go. I never drill straight to the size unless it's 1/8 or something.

Yeah that was 10+ years ago and I was still a teenager when I tried that, I've learned a LOT since then (and broken many drill bits and ruined many holes in metal LMAO). If I did it again I'd use a drill press and work up from a smaller hole and/or step bit and take it really slow with minimal pressure.
Dam, nothing like taking over someone else’s thread. Should of started his own. Kim
