I knocked this up after work while having a beer. It's a PCV valve adapter for my 230 Dodge. Not finished yet, but on the way. Just need to work out how to make it look like a casting. Louie
Toss it around on the concrete floor a couple times. Then sand blast it, Well, you wanted the casted look didn't you?
I was thinking about masking off some areas and grit blasting it, mainly inside the grooves. Might also put it in our parts tumbler with some course media and rumble the edges for a few hours. Yes, it has an O ring that seals on the diameter of the hole in the block. I'll also put a Dowty washer under the bolt head to seal the bolt hole. All I have to do machining wise is spotface the side and drill & tap for the appropriate fitting. Just need to work out what that is. Louie
