I was changing the oil on a Ferrari 330GTC when I found the oil pan plug super tight, and when I went to replace the drain plug, me fears of stress on the oil pan plug came true when the thread pulled out. After years of over tightening the oil pan plug from another shop, the thread decided to pull out on me!

Before getting the threads repaired, I first needed to clean the the oil pan. There was a bunch of sludge and thick oil oil trapped in the baffles that does not drain out at every oil change, and through the years, it builds up in these channels. Now was the the time to clean all this sludge out.

The owner told me the oil pan had always leaked a little, and when I was removing the old gasket material, I could see why. This oil pan had a machined surface on the surface for the gasket, but the grooves were probably allowing a little oil to seep by.

There were deeper gouges from a worn gasket scraper that left some deeper scratches that were also contributing to the leaks. Hopefully a light smear of RTV will help seal this oil pan to the bottom of the sump.

I shot a video of the process and it can be found here: https://youtu.be/oSHg61xUjkU?si=–44eug90Xlr80DC&t=932
