Ok so I jus got my swap running. It's a gsr with type r pistons, rods and crank. It idles high at like 2 grand then sometimes it will idle high then low. Also it smokes when I gear down or take off from a light, alot like a complete cloud And there is oil leaking out the rear main seal really bad, like almost a quart a day. I'm thinking it's building up pressure and shooting a glob out onto the headers. The motor drives really choppy too. I'm thinking my crank case pressure is off but idk how everything is hooked up right as far as I know. It's hard to tell bc it's open header and I can't see where that puff of smoke is comin from. Could it be blow by or rings bein bad? If anyone has any ideas that would be great. Thankyou!
