I recently bought a07 Yukon Denali with the 6.2, has 250k miles so it’s not new by any means lol. Runs and shifts great though. Now I’ll be honest, I’m no mechanic. I know how to do the basics but that’s about it. I was changing the oil today and went to change the filter when I noticed this hole behind the filter. Now I would assume these teeth shouldn’t be exposed like this but I honestly have no idea what I’m looking at. Any help would be greatly appreciated.
