Bruce Nunnally Posted March 21, 2014 Report Share Posted March 21, 2014 Well the parts manager was right; the O-ring seal on the cap side of the oil filter housing is reusable. General Motors has determined it is only reusable to a certain point. They even went as far as to assign a specific mileage of exactly when the seal is to be replaced. This magical number is 50,000 miles. If I sound a little sarcastic, then I didn’t do a good job of hiding my feelings. I truly believe that the seal should be replaced on every oil change.

rockfangd Posted March 22, 2014 Report Share Posted March 22, 2014 no doubt a very good read. THis brings up a a good point. I work on diesels on a daily basis and cartridge filters are used from most everything, from oil to fuel, etc... and I find that when the cap is installed without lubricating the oring it causes it to stretch during the removal and install of the cap. I would not necessary feel comfortable with relying on a oring for 50k miles but would not expect to pay 7.00 for a o-ring. I wonder what the logic was behind the decision to not replace the seal with the filter and to sell it seperately. I found no sarcasm in the writeup and thought it was pretty thorough. What about aftermarket filters? If there are any do they come with a seal, or are they the same as the oem filters?

Z15 Posted March 24, 2014 Report Share Posted March 24, 2014 They are wearing out the seal changing the oil too much...LOL I have used a Wix 57090 and it does not come with the o-ring seal. Mike Synthoil Supply Link to comment Share on other sites More sharing options...
Z15 Posted March 24, 2014 Report Share Posted March 24, 2014 I just called my friend who is an AC Delco dealer/repair shop. 12577653 is a AC Delco part # as well and he told me my cost was about $3 and btw, about $5 for the oil filter. Note - GM parts for the most part are always cheaper from an AC Delco retailer Mike Synthoil Supply Link to comment Share on other sites More sharing options...

cdgrinci Posted March 25, 2014 Report Share Posted March 25, 2014 Under $3 at Rockauto; they also have the oil cartridge cap for around $25. My Intrigue (3.5 L engine with same cartridge but different cap; had two "O" rings) never leaked and was never replaced (after 14 years and nearly 140,000 miles); used either the same of similar "O" rings).

rockfangd Posted March 25, 2014 Report Share Posted March 25, 2014 wow. Must be the design of the material doesnt stretch like regular seals. Likely made with silicone GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
