Guys I forgot to mention, the bottom right corner where there is that black stuff is also where the PCV valve is situated. Does that have any correlation?
And, the exhaust valve spring keepers are dirtier than the intake. Why is this?
If you notice the exhaust rocker arms are Y shaped, could this be causing less oil flow over the exhaust valves and hence more crud accumulation there?
