94 Road King. I bent a valve about 6 months ago so I took the heads to the machine shop for a valve job and put new rings in while I was at it. Since then it has blown out the front rocker box gasket 3 times blowing oil out. I'm talking about a quart in about 10 miles. A real mess. Was advised that it was the vent restricted so I took the banjo bolt completely out last time. It didn't blow out the gasket this time, just dumped it out the enlarged vent hole. It has done it running 70 or 80 on the hyway but also once just running around 50 in town. After the bike cools down it stops for a while, but then suddenly comes back. Any advice would be appreciated.
