question about cooling your engine oil
I run a shorty too, but the seal leaks when the filter's frying. Does yours have that problem?
No,that's a separate issue'
Your system may be under too much pressure, or
the filter may not be tight enough,or
it may not even be the filter that is leaking.
When my engine was fresh, I installed 15W40, cuz you know, that's what we do when we think we have a race motor. Well that worked ok until I got on it, then it spewed oil onto my header, causing copious amounts of smoke. So, I'm no dummy; I put 10W30 in. Still the spewing persisted.
Well said I, maybe I am a dummy.
I had done the high-rpm oiling mods and I had installed a hi-volume pump.And I was running full capacity in the Milodon 7 qt roadrace pan.And you gotta know this; I was spinning it to 7200 with the Mopar 292/108 cam. So, I asked, how can I get rid of some of this pressure?
So I popped the valve covers and doubled the oil-clearances at the rocker arms; you know, shaved the spacers between each pair. Good to go right? Not. That made no difference,and after I thought about it some more;DUH, I am the dummy.
So them I put in 5W20, with great trepidation. That's gonna cure it right? Not.
Ok so now, I'm getting concerned. By now I had tried several different brands of filters with no difference, and I had checked the gasket between the plate and the block,even changed it. And I was not excited about running 5W20.
In desperation. I doubled up the plates, and drilled 4 more holes in them, for a total of 8 holes.
That cured it.No more problems with 10W30 or 10W40.
The restriction was right there at the the plate.
So, there ya go, pull the plate off and drill at least 2 more holes the same size as is on there, Or like I did; 4 more slightly smaller ones. Debur and chamfer them all, and away you go.
BTW
You can tighten the heck out that filter without fear of hurting it or the spigot; the mounting nut is not the weak point. At least not on any of the ones I tried,lol.
I can't say if doubling the plates is necessary anymore, but they're in there at least until the next time I take it apart. Why mess with what I know works. The funny thing is,if you add up all the area of just the oem 4 holes, it is well in excess of the largest gallery in the delivery system. Soooooo was it the extra holes, or the doubling, that cured my woes?

That 367 engine has seen two other cams after that Mopar-brute , And I have spun them all to 7200, for a lot of the time.......and she has accumulated over 100,000 miles since inception in 99. I did take it apart the first 4 winters for inspection; I figured gaskets were cheaper than losing her. And the first two times I found problems budding. After upgrading as required, no more problems.So after 2004, she hasn't been open again, except to swap cams.
