Pro Comp intake on 340 motor. Aluminum pro comp heads as well. For the heck of it I checked the intake bolts and they were loose. Tightened them up and the little plug on right rear is spewing oil out everywhere.Is that a crosswind intake...with plugs for the magnum bolts?if so...do you have the PCV hooke up? OIl vapor.....clean..and use some clear rtv around the plugsok..I see pcv hooked up in picture....
Yours is the 2nd thread I've read lately concerning oil leaks. I think they come in 3s. - Or is that celebrity deaths?
The intake MRL installed on my 408 had similar plugs. I tried to remove a few that interfered with my throttle cable mount and couldn't get them out. I ended up just grinding them down. I would imagine that any of yours that are leaking might be removable with more effort. It sounds like a pain in the butt but I'd pull the intake off if you can't get the plugs out otherwise.
Mine are dry as a bone. The intake was already installed on my motor by Mike at MRL when I received it. The only reason I attempted to pull out the back 2 plugs on the left side was the clearance issues with my linkage bracket. I sure couldn't get mine to budge. When I started grinding on mine I was afraid I might grind through but I figured that I'd pull the intake off if I did. Luckily they were pretty thick. I have less than 2 hundred miles on the motor so far. No oil leak issues anywhere but I did have a problem with the spark plugs not seating and switched to a tapered spark plug.Did yours leak as we'll? Mine literally spews oil out of it. I could literally power my oil pressure gauge off of this plug. Is that normal if the plug isn't sealed tight? Just started doing this out of the blue!
Previous owner of my 318 installed Edelbrock intake and valve covers and oil would leak onto the intake. Not as bad as you describe but a PIA nevertheless. Turned out the valve covers were hanging up on excess metal on the intake. No leaks after I ground away a bunch of material.
Perhaps by tightening the intake the valve cover to head gasketl was somehow upset???
You should use some liquid teflon on the intake bolts. The oils getting pushed up the bolt threads, collecting under the plug, then spitting out when there's enough there. I tapped and plugged them on the one I used because the plugs they gave you didn't fit well - as int he holes were sort of round and the plugs were sort of round but they didn't seat 100% around. Another magic part of the Crosswind.
Definitely not a simple bolt on and roll. A lot of weird issues.The joys of aftermarket parts. According to some, If you don't look forward to these sort of problems and you don't have more wear in the hood hinges than in the door hinges, you're not a enthusiast. Good luck with it.

What did you do on the pro comp manifold to stop the oil leak at these Plugs ? Whatever you did seems to have worked , the pro comps you have used for customers seem to hold oil . Never had a problem with my Air GapLOL Welcome to MY World! I do believe there is no such thing as "bolt on and go". Procomp to Jesel, its always something.
Cost less fill bolt holes not used, mag holes on la engine ?Maybe I'm "behind the curve", but why use the Procomp manifold? I'd also like to know why do they have these plugs? Looks mickey-mouse to me.
I had to clearance my Weiand Stealth to clear my Holley valve covers.....both parts are made by the same company and they still needed "fit". My neighbor spent two days grinding the ARP heads studs of his sons BBC because they interfered with the headers and we all know how well their main studs fit the oil pump on SBM's....Welcome to engine building.
