So, several years ago I took on the task of changing the oil pan gasket (also did motor mounts the same day). I used the cork gasket (gasp!) and black sealant (silicone I think). Everything went fairly smoothly until I went to bolt up the pan and two bolts sheared off (one in the front and one in the back). Each bolt was installed using a torque wrench, so I’m not sure if those two bolts had weakened or what happened.
This past weekend, I went to try removing them and was able to get the front one out easy peasy. However during the aft bolt removal, the tip of the ez removal tool broke off inside the hole. After a few hours of trying to get back where I started, and I’m left with a pretty boogered up hole that appears to be past the point of recovery with the original threads.
i have an M6 helicoil (E-Z Lok) coming in the mail, and without intervention, I plan on pulling the pan down again, drilling and tapping a 3/8 hole to install the 3/8 OD M6 ID helicoil. I will also use the “aftermarket” Victor Reinz pan gasket from Blunt, because it looks like the cork/silicone method didn’t stand a chance. I’ll probably try tacking this on Saturday, so if anyone has any experience with doing this or sees any red flags in my plan, feel free to steer me back on course.
