There are no 'revised' pickups. Dealers will sometimes use a different version, but they all have a history of breaking. The three most popular part numbers (back to 2002) end in 050, 070 and 110. I can give some specifics about which ones break when, generally, but they all break. Basically failures have occured since these pickuos have been used on EJ engines going back to when they came out in 1993. The earliest I've personally seen was from a 1993 with 205K miles.
For those that don't have the time/budget to use our ultimate pickup and go with another OEM, we recommend changing them every 20K miles. The probability of failure below 20K is VERY low.

Best thing to do, ifyou suspect something. Don't run the car unless you get a mechanical gauge to verify pressure. The OEM light comes on at 2.1psi, which is essentially nothing.
