I have done this to gas tanks and it works great, you don't have to remove the tank, or pan in your case; Drain your oil and jack up the car so there is no oil around the pin hole, or holes. Let it sit for a day so that all remnants are away from the pin holes. Clean the hole real good, I use starting fluid, and find a screw slightly larger than the hole. Put a dollup of oil safe sealant around the screw and put it in. Finish with a little on the outside, let it cure for a day, and your good to go. If it doesn't work you can proceed with other trys......Russ __________________________________ Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers! http://promotions.yahoo.com/new_mail
