When do I know I should change it ? My car has 220K miles on it. The alternator looks pretty old. Can it suffer a catastrophic failure or will it warn me first ?
the alternator on these cars is really not a trouble spot, there pretty good. most likely is that it'll fail and you'll have just enough battery to get home, or your car just wont start in the morning..

This is one way to test your PCV system to see if it is bad/plugged/clogged. Start the car and drive it until it is warm. Once it's at its proper operating temp, put it in park, open the hood, pull the oil dip stick 1/2 way out. If you see grey smoke coming out of the dip stick hole, it is bad. Replace the entire system as soon as possible.
