Leaking valve seal
I hadn't drive my car for a couple of weeks and started it the other day and had a flood of white smoke on start up, i drove it around the block and could hear some faint popping from the exhaust. I recently swapped intakes and wondered if the intake wasn't sealed properly. I pulled it off and everything looked fine. I shined a flashlight in each intake runner on the head and found one with about a table spoon of oil on the valve. I guess that's my culprit. The popping makes me wonder if the valve is sticking? Should I just the pull the head at this point and look everything over or just replace a seal? It's a 383
