Oil pan gasket on 3406E.

The gasket is a LOTS of piece one if you buy from CAT. It is like a puzzle. Cat sells special glue to glue the gasket to oil pan. Then you can use RTV to seal it to the engine block.

 

If it is only coming down the bolts, you can remove them and take some solvent, I use an old mustard container, sqirt it in the hole and blow it out, then coat the bolt with silicone, and reinstall it, torque it to 35 lbs. On an "E" you want to look at the middle of the pan they have a cracking problem there. If you take off the pan use Silicone on the pan a very thin layer of Loctite 5699 and a little more on the seams. You never ever use glue on any gasket it dries them out and they leak.
Just a thought!

 

If you read what he wrote again he said that the glue dries out the gasket not silicone. There is a difference.

 

Ditto, and he also said to clean the holes out and use silicone on the bolts before reinstalling them, just re-torqueing them probably won't help much. I hate the Cat puzzle gasket, IPD has a one piece gasket I really like but the only way I've been able to get them from TruckPro is with an overhaul kit. I tried another one piece gasket years ago (can't remember where I got it) but it was very thin and leaked something awful, maybe if I had used more silicone, don't know.

 

If you use CAT gasket then you have to use that cement to hold that PUZZLE on the oil pan until you ready to install it. Cement part #54-2471. I am not a smart ###, just did what CAT advised me to do 7 years ago. No leak today 7 years later.

 

Because that is what cat actually suggest using when putting the gasket together, and they do sell the stuff. Your the one that assumed that he was considering silicone to be a glue, and because of that you were questioning his post. If someone correcting you means their a smart ### then so be it.
