Brand new ‘21 GMC LM2. 7,200 miles. Was scoping out what I needed to do for my upcoming oil change, I discovered this.
Is that a crack in the casting? Before I proceeded messing with it gonna have the dealer take a look incase I need to use the warranty. Do you guys have the same grinding marks mine does?
You could put some engine oil dye in it before you change the oil and let it run for 15/20 minutes and see if the dye shoes up. You will need a black light to see the dye, but they aren't very expensive at the parts store. I use mine all the time for different leaks. coolant. trans fluid p/s fluid a/c leaks.
Nah, not a crack. Just looks like a high spot that has oil accumulated on it. As stated above clean it and take another pic. Your oil leak looks like it’s coming from the seal area.
I’d say they cranked it on too tight on the filter and it’s pushing out when the oil pressure goes up. It’s definitely NOT loose. Haven’t done many pulls and haven’t hauled anything yet.
Just wanted to make sure it wasn’t coming out of a casting defect or something before cleaning it up or doing an oil change myself. That way I wouldn’t have to deal with a stealership trying to deflect and make things unnecessarily hard if it was a problem with the casting.
True but since GM baked it into the msrp and offers it, already paid for when you bought so might as well use it, they also bake in the $100 in rewards you get, might as well use them for the 2nd oil change.
Looks like it has already had an oil change to me. I've never seen a new truck with an AC Delco label on the filter. The factory filter is usually just blue with no label. I bet the lube tech was in a hurry and made a mess.
