I thought I was getting blowby pressure of the crank case but I crawled under today to find my oil pan gasket edges moist... thought I was on to something... until I found the flowing drips from the back edge of the valve cover. The breather has always fit loosely causing some pooling but I can now see chunks where the cork gasket is hanging out almost 1/2" and is soaked in oil. I suppose I can blame the shop during final assembly who rebuilt my motor. Wow that was 10 years ago, time flies.
My plan of attack is to redo the gasket and while I'm at it tap the VC breather and do a VC & PCV catch can setup.
Is the rubber Ranger gasket still the best one to get? Any other tips?
I think the Ranger gasket is still available, but it isnt cheap.

I'll bet RDOG has one, gonna hit him up.
Stinger has a catch can approach well documented. Does anyone else have pics or have tried anything? I don't want chinesium ebay anything.
There are Moroso catch cans on Summit that would work. Kevko also has some nice kits but they are maybe overkill.

Got a Ranger gasket. Decided to upgrade the breather while I'm at it and skip a catch can.
Gonna drill out the breather hole to 1.25" for a Moroso 68781. I'm thinking the early style breather that's only 3/8" along with my slightly kinked 3/8" hard line to the intake may be what's to blame, along with the leaking valve cover itself.
Easy peasy. Got a 3/8" line from Autozone for $8, with both ends have fittings matching stock, cut it in half so I have half leftover. Got a tube bender on Amazon for $14 and the Moroso 5/8" breather for $15. All in, including new valve cover gasket, less than $70.
You can see how pinched my stock breather line was. It still necks down at the intake so I couldn't run 5/8" there anyway without a new hole. If this doesn't breath good enough then I'll consider 5/8" to a catch can.
You can also see exactly what's not recommended is what the shop who built my motor did on the valve cover. Over torqued and torn clean through, and globs of sealer on the front cam tower. No wonder it was pouring down the back and onto my new exhaust. Well not any more!

Cool deal! I’m going to build something a little different. I build a lot of AN lines for my race car, so I have some left over stuff. I’m going to do a Moroso dry sump catch can and with -6an line to it. And leave the PCV side still hooked up.
