Default Pressure relief valve question

Hello all,

I’m brand new to Harley having just picked up an 03 Electra Glide. I was told by the guy I bought it from that I need to depress the pressure relief valves in each cylinder before each ride. I have no experience with this at all and this morning forgot to click them down before riding to work. During the ride, had oil low out from under the intake cover in the right side. Is this a possible side effect of not relieving pressure before riding?

When am I supposed to use these relief valves.

Thanks for the help in advance

They are called compression release valves, they make it easier for the bike to turn-over and start. They have nothing to do with the oil leak. Oil can come out the intake if over full as a result of it coming out the breathers.

Chances are you have a 95" or larger engine, for those compression releases to be installed.
The air cleaner oil can be helped often by lowering the amount of oil in the tank by approx 1/2 quart, but better yet, open the breather drains in the rocker support plates to .130" +/-, something we do on every build here.
