Question Oil Pan Fix

I recently ruined my day having my floorjack slip into my oil pan and damaged the front shallow section under the crank. Now its banging.

Anyone know of a quick and easy fix to pull out the dent? Its about the diameter of a short stack pancake. I heard its possible to loosen the motor mounts and raise the motor enough to replace the pan. Its the frame that looks in the way.

I also thought of draining the oil and try to pull the dent with a body shop stud welder / puller

Thanks

Steve

Re: Oil Pan Fix

No amount of minor loosening will allow a BBC pan to be removed with the engine in the car. The flex plate or flywheel gets in the way of getting enough clearance. You might try the stud welder/ puller idea.

Your just jealous because you can't hear the voices!

If the dent doesn't have a very pronounced crease, you might get away with the stud puller. My concern would be the stud making a hole in the pan while pulling. Kinda hard to weld up a hole in the pan with oil dripping out. I would pull the engine.

Yeah, Keith is right. Pull it to fix.

X2 It's the best way to fix it. I'd buy a new pan if money allowed.

If you lend someone $20, and never see that person again, it was probably worth it.

I have had good luck with the pans that summit sells. No name on them, but solid pans.

Re: Oil Pan Fix

I had the same problem with a 4.3 S-10 when installing new motor mounts, I used a stud gun but it took near 2 hours to achieve what was needed to clear the crank.

My 2 cents,Mike

Re: Oil Pan Fix

Did this on a small block. Fabbed a 3/8" bent rod with a flattened end. Formed it into a hook and fished it through the drain plug bung and worked the dent out for the most part. You have to consider the clearance of the pickup also, it needs to be at least 1/4" off the pan.

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.

Re: Oil Pan Fix

I don't think the drain plug access whole will fly. The ding is towards the front of the pan . I don't think between the crank and the windage tray is enough clearance to attack it that way. I will try to fire up the stud welder . If it gets too hot and I blow through, Im not so sure Im a good enough welder to seal a hole there

Re: Oil Pan Fix

I'd try the stud puller first - if it doesn't work out the way you want it - pull the engine. It may take several studs to work it out gently and to clear every thing inside. A pic may give us more to go on.

Re: Oil Pan Fix

As long as there are no creases involved and simply a matter of popping/pulling out to clear crank:



Measure how wide the pan is and size puller for exact fit.

Re: Oil Pan Fix

Has a crease on the circumference of the ding . I just received a dent puller gun that uses epoxy hot glue. Will report on results later
