A relatives car has a thick oily substance on the PCV valve and in the valve cover where the PCV valve is located. Given this indicates that it has not been changed in a long time and that the oil was probably not changed often, how can I be sure that there is not any substantial damage to the engine? and what parts of the system should be cleaned given this oily valve?

Its from a long life of unchanged oil and crude build up. You can clean out the motor sludge with those engine oil additive. But it wont clean the emissions lines. They would have to be physically cleaned or changed. The PCV feeds alot of vacuum lines and intake systems. The one way to prevent it from getting worse is to start using synthetic oils, cause they dont cause buildup and in somecases clean things up.Oil laden PCV valve in 2002 Chevy Malibu?
The only way to be sure of the internals of your engine is to remove the engine and tear it down for inspection, but oil pressure is also a good indication of engine condition. Poor oil pressure indicates oil passeges blocked or more likely worn out pump and bearings. You can buy additives that you add to the oil to help beak down the sludge befor you do an oil change.Oil laden PCV valve in 2002 Chevy Malibu?
