I recently changed an engine from a 79 Camero into a Chevy blazer. The engine was used and sitting in a carport for 8 months or so. I didn't think they would pull an engine unless it was going strong. And they swear that it didn't smoke at all when they pulled it. But when I put it into the truck and did a complete tune-up and even thru a rebuilt carb for that year on it smokes from the passenger side. I think its number 8 cylinder. It gets covered with grease and fouls. Is there something that might be stuck in the engine that I am not finding like rings or some more time to wake it up. Or did I get screwed by my GF dad?
I ran compression test on it before I installed the plugs I got 130 on all of the plugs except number 2 but it has since gone up to 130. But number eight is oily. And that was the cylinder that was fouling in the old engine. I don't know what is going on?
