Oil filter cover

Dealer is the only one thats changed the oil. Problem is oil is leaking at the oil filter cover. I suspect they cross threaded the threads in the engine. They replaced the cover and gasket. Is there any way to fix these threads? Oil leak is bad. 45k miles Thanks

Check O-Ring on filter cover. Most likely they re-used your old o-ring gasket. Sometimes you get by with it, sometimes you don't. I replace every change. Any other problem will be very obvious just by looking at it.

my o-ring went bad and had to switch it. the one I have isnt perfect but it works better than the old one. No leaks since. So yeah check that like GTO said. Speaking of which I never got a real chevy o-ring or one with my filter or anything. Where do I get them?

The last oil filter I bought came with a new ring. The oil change before, the filter did not. I guess check the box at the store before you buy...

I replaced my ring and it was fine, had just a minor leak but got it to stop by replacing the whole thing

if the dealer is the only one who touched it. i would just bring it back to them, let them know it STILL leaks and have them fix it right! good luck!

Thanks for the replies. The second to last oil change they must of not installed the cover/ o-ring propely. On the last oil change they did a Goodwrench multi-point inspection like always and there was a note (Engine oil leak) So I took it in the next day and they replaced rocker cover gasket, but that wasn't the fix. Took it back in yesterday and they replaced the filter cover. I hope its fixed. I don't know what tool they are useing but they really rounded the nut on the new cover. I might change the oil my self next time to see whats going on. I need a 32mm socket?

I'm sure it is a 32mm, but not sure about space for socket and drive. I use a 12" long adjustable and it works perfect. One of the easiest and least messy cars to do an oil change on.

yeah what I do is use the socket until its loose enough to do by hand then remove it, then do the opposite to put it back on. Zoomer's right, easiest oil job evar!
