Crank hitting oil pan?

[Vin Man]

Now that I've got the Mustang running, and the new exhaust, its time for cleaning up the little details.

I have a tranny leak and had the car on the lift today looking for the leak while car was running. I've had a clanging sound coming from engine as well, and was hoping to find it. Looks like I did.

Apparently, the crank or connecting rod is hitting the oil pan as the engine runs. If I put pressure on the oil pan, I can feel it and the pitch changes.

It is the same oil pan that was originally on the engine, so I'm a bit surprised by this developement.

I'm thinking that once I remove the pan, I'll have to "persuade" it away from the crank/rod using a hammer. Or, look for a different design pan.

The contact is coming about 6 inches from the rear of the oil pan.

I had this problem on my old oil pan. It happened because the guy I bought it from had lifted out the block with chains under the pan. It can also happen if you let the engine sit on the pan for too long.

I pulled it out and with a combo of a propane torch and small mallet, I hammered it back into shape. Tap lightly. First pan I did this on ended up cracking.

I had the same issue with a 200 inline six and found that removing the oil pan revealed a wear spot where the conecting rod made contact inside the pan. I used a hammer and dolly and tapped out the low spot in the pan which solved the problem.

I had a similar problem, but it was that the oil pick-up was too close to the bottom of the pan and thus rubbing and making growling noises - echoed by the shape of the pan.

I used a foot-long piece of pine 2X2, a hammer, and the sandbox to re-curve the bottom of the pan. The reason for the sandbox was to not let the metal stretch too much. The wood 2x2 was to easily reach into the sump and to soften the blows ( like a rubber mallet)

Good Luck

We were able to do some creative pounding with engine running and got it fixed.

Same thing happened to me when I strapped it down on a trailer to take the car to my new duty station. It is dropped in the front end anyway and with the trailer ramps underneath the car.........well you get the picture. After my buddy and I spent the weekend throwing the hole motor together, minus the block which was already in the car, we gave it a crank and heard the clangs. After a couple seconds of careful listening, we realized what what going on and deduced that I must have bent the pan. Just had to remove the oil pan and pursuade it with a ball-peen and forming block. Didnt take much but lesson learned.
