Re: You guessed it, 1950 s10 swap.

I had the pcv system all screwed up. I was putting way too much vaccum on the heads and i guess it was forcing oil into the cylinders. I changed the valve stem seals and it got a lot better. Only did it under high rpm after that. I took vaccum completely off the heads all together and vented both sides and it started running great with no smoke. Put the exhaust on and it stopped running rich. Finally got all the air out of the power steering system. Had a scare last night tho. I pulled my radiator cap and there was black sludge at the top. I immediately thought head gasket was screwed. Isnt running hot tho. I let it settle and went back out there it was just on the top. Im just guessing it was leftover dexcool that was in the block that i didnt get all the way out. It does that when it mixes with green coolant. Getting an alignment today hopefully and ill be good!
