Well, as usual I decided to work on my car and something went wrong. I was doing a routine oil change and the oil filter cap is stuck. The cap has rounded off to where the socket isn't getting the grip it needs. I really don't feel like spending hundreds of dollars at a shop for a $15 part. So, does anyone have any DIY tips? I was thinking of piercing the cap and then using a screwdriver and hammer to see if I can get it loose. Another option I saw was to heat a 31mm socket and basically melt it onto the cap. Any help would be greatly appreciative!

 

Channelock pliers worked for me
The OEM cap is 32mm but can get rounded of if you use an adjustable wrench or 1 1/4 inch socket

 

Order this first!!!

I tried the channel locks, but can't get it to budge.

 

I already have an oil filter

 

Yes but that comes with the oil filter cap.

 

And it is cheap for the combo! you will get a basically free filter for the next oil change and you will get the OEM green oil filter cap O-Ring that (debated by some) doesn't need to be changed with every oil change. I have gone through many oil changes since buying that cap and not a hint of a leak without changing the o ring.

 

On top of that, unless you did it and dint realize, I would go to wherever you last had the oil changed and give them a few words... and not go back there after that LOL

 

Yeah that's what I'm thinking of doing. I'm probably 75% sure the shop I took it to last cross threaded the cap back on. I took an impact wrench to this sucker and it still won't budge. I just called a tow and I'm going to take it a shop

 

Who rounded the cover off?

If it was cross threaded it should be leaking.

I would be thinking drilling a hole across the "nut" part big enough to put a screwdriver through then twisting.

It is plastic, so breaking it is an option.

Get the correct tool for the future. It is listed in the aforementioned Amazon link.
