Oil drain plug gasket material stuck to oil pan?

I just bought a 2011 Tacoma and tried to change the oil. Once I removed the oil pan drain plug, I found the blue rubberized coating normally on the drain plug gasket face has stuck to the oil pan. The gasket came off with no more coating on it. I tried picking at the residue, but it's rock hard. So, I decided not to try scraping it off with a knife as it might leave deep scratches on the mating surface. Has anyone had this issue?

 

Just scape it off next time and the new gasket will fill any voids. Toyota gaskets are pretty good at this. Nothing to worry about.

 

It happens, pop off the washer and replace it if you have a spare. I tend to use the washer 2 times or so, then change it.

 

Carbide scrapers are made for stuff like this.

generally better than roloc especially for internal engine work where roloc/scotchbrite can make uneven surfaces and contaminate with abrasive debris

carbide scraper works better than a razor blade.

auto parts store might have one.

 

Was the oil pan still warm when you drained? I usually use a razor blade to peel off the washer since it does get stuck each time, and it's easier to get a clean release if everything is still kind of hot.

 

Thanks everyone for your quick responses. I managed to scrape off the "bake-on" residue with a plastic chisel. No apparent damage to the paint finish on the oil pan. Whew!

 

Mine was stuck on the same, left it for 9 oil changes, never leaked. It popped off by itself when I swapped in the fumoto, perfect timing.

Those Toyota gaskets are pretty good. I think glass filled nylon.
