serious 60 rough idle when warm

[Chamberpains]

Did you replace all the jake solenoids? Also, what spring was damaged? Did you pull a solenoid apart (solenoid springs are inside the solenoid housing) or did you just see 1 of the valve springs and retainer snap rings broken and busted up. Cause if thats the case, you have a broken valve spring and the valve is not closing all the way. Its mis firing because you are flirting with dropping a valve in the cylinder.

Something happened to damage the overhead components. More than likely a careless mechanic forgot something in the overhead last time it was opened up, flat worn out overhead parts or one of the valve buttons or cages broke loose and flew around busting everything it can till it finally found its way down an oil gallery to the oil pan. You need to open it back up and reevaluate the damage and fix it.

And to answer your solenoid question, yes they fail open some times and oil will pass thru causing rough operating.
