Camshaft Green Seal Leaking

[JFP in PA]

The use of too much, or the wrong type of sealant, will cause these plugs to move and leak.............

I thought the plugs were supposed to be installed dry? The sealant I used for the cover was from Sunset and it's what they suggested I use. I did try sealant on the plug(after about six dry runs with it just blowing the plug out) just to see if it would hold. It lasted about 2 minutes and then the oil pressure forced it back out.
Is there any way that oil can get in, but I clogged up the way it goes out with to much sealant? I also was thinking that the plug could be defective and a little smaller than spec.

Yes, we've seen this problem before; the issue was too much sealant applied to the cover, especially near the end cam journal that was causing a build up of pressure that was pushing out the cam plugs (installed dry)..............use the sealant sparingly........

That side of the engine was a tighter fit than the other. I almost remember putting more sealant on that side just in case I smeared some against the cam while reinstalling it.

Thanks for your help, I'll try resealing it this weekend.
