"2008 oil change...FYI...
For those who have not yet done an
oil change on their 2008 (probably 2009), the drain
plug requires a 13 mm wrench.
Interestingly, the NEW 08-09 Viper specific
MOPAR oil filter (05038041AA) was a slight disappointment in that the rubber gasket was loose
when taken from the box/plastic sack/plastic cover cap. While I have been using the ''other'' Viper specific MOPAR filter
(05037836AA) for a couple of years on all of our other Vipers, I have not seen
this type of problem before. (SEE UPDATE BELOW)
Anyone else seen this on the 08-09 filter...or am I the only one??" (later, we found the answer was YES...including a late blowout of the gasket on a friend's 2008 Viper which netted a street full of oil and a ride on the "hook"...which was actually a flatbed!!!)
.........................................................................................................................
UPDATE: there have been several confirmed issues with this loose gasket on some batches of the Gen IV oil filter (05038041AA)...so GREAT CARE must be taken to be sure that it stays properly centered in place as one EASES the filter into place (NO SPINNING !!!).
After my post above, I began to see the same loose gaskets on a bunch of the Viper specific GenI-III filters (05037836AA)...noting that the Gen I-III filter has undergone an update (different reason than the gasket issue) and is now called 05037836
AB.
Since experienced Viper techs have reported similar issues, my advice and my own procedure for our Vipers has been to inspect the filter with a mechanic's mirror from all angles during installation to check for asymmetry of the gasket (buldge)....and if it looks good, fill car with oil, run car on lift to check for leaks, followed by test drive, then recheck on lift, then watch for drips long term.
Looking forward to my Spring oil changes so that I can try newer batch of BOTH of these filters.
