Re: Oil Pan Fix
I did the same thing on a 454 oil pan in a Chevelle a couple of years ago. I used a stud gun, pulled out the dent, and repaired it in the exact same manner as if it were on any other sheet metal body panel on the exterior. I would only pull that engine as a last resort and not the first thing to do as some others have suggested. I had mine completely repaired with an undetectable repair in less time than it would have probably taken to change the oil pan if the engine was already out of the car. Even if you pull a hole with the stud gun, you call still weld up the hole(if you drain the oil first) and proceed on with the repair. If you currently have no oil leak and pull it just to eliminate your psychological feeling of " I don't want to half ass it" , then you have the possibility of it leaking at the sealing surface after you change it if you don't get something perfectly clean and aligned during the replacement". And if that happens, you get to pull it out AGAIN! If you do it my way, you can spend an hour or so to see if it will work, and at the most, all you have wasted only a little time if it doesn't. If you pull it, you risk damaging things, it leaking at the mounting surfaces, and at minimum, a full day if not two days work ....... .....Just my 2 cents.......... I would just hate to see you go through all of that work for something that may have a much easier solution. But if you are looking for an excuse to pull it out to do some improvements and/or cleaning and painting inside the engine compartment...........well that's different. Good luck with whichever path you take.
