340 motor pumping excess oil on right side
i agree the warner pcv is a good mod to make either way
Are both valve covers baffled like the one pictured in post 6? If so, that's a pretty efficient baffle.
I'm just spit balling here...if you have an old valve cover you can cut the top away (I used to have a couple of those laying around but I 86'd them a few years ago or I'd just send you one) and then bolt it on and actually look at how much oil is up there and where it's coming from.
I'm at a loss to think of a way to explain how there is excess oil getting to one side only. Unless you have a rocker shaft with a split in it or something (that's another spit ball right there) or the rocker stand where the oil is fed to the shaft is fractured or something oddball like that.
The Chrysler oiling system for the rockers is self limiting for the most part and I'm at a loss to think of what's going on on that side.
The other option is just pull the distributor and drive gear and put your priming tool back in there and spin the pump up and see what you get.
Don't forget you need to turn the crank over until you get the oil holes lined up.
And of course, I can't remember exactly where the crank has to be to get oil up to that side but someone here will remember.
That's about all I got. For now. I'm sure I'll wake up at about 3 AM with some other corn ball ideas.
