I'm thinking maybe burnt oil but not too sure. The oil still has a thick consistency as well. Also, last month, I adjusted the valves because I noticed that some of the pushrods were really loose, but I did it with the motor off and I just manually turned the motor over.
Here is an article on adjusting valves with the engine off. Camshaft - Car Craft Magazine. Another article from Wiki on this website (HotRod) that covers about everything you need to know to adjust your valves.
