These guys are so crooked that I have filed a complaint with the BBB. The "great" mechanics here have never heard of a re-threading kit. They drilled a hole in my oil pan. With in a few months that hole cost me $500.00 plus interest, for the loan I had to get, to keep my car running! Champs Auto said the hole was way too big and also tried to sell me a new oil pan. I finally had to take my car to AAA because it was leaking so much oil after I went in for a simple oil change at Champs Auto. AAA also said the hole that brakes plus drilled in my oil pan was very large. DON'T GET SCAMMED. Here is a video on how to re-thread the oil pan. https://youtu.be/NbbNR6PzU1E
