I have a 2000 Silverado and a few months ago took it to Jiffy Lube and they over-tightened the drain plug to my oil and now I have a drip from the plug. I have tried an aftermarket gasket but still seems to drip. Has anyone tried like a silicone tape on the threads to help with a leak? Will it be affected by the heat? I hope the threads are not stripped. Any help appreciated.
