OK, it's my turn.

145,000 Miles. I noticed puffs of smoke when idling. I have already replaced the PCV Caps and diaphragms - no soap. When I got home today, I let the car idle and for about 4 minutes there was no problem. Then a little smoke started flowing from the left exhaust. a minute later it was also flowing from the right. Another minute after that it was like a bug fogger went off.

So, if I look for a used AGA tools kit, is there anything in the kit that could be damaged or bent and therefore make the kit not worth the money?
