Dipstick into pan gasket?

Post #1 by rratselad » Sat Jun 23, 2018 12:55 pm


I have a 1970 240 that is back from the machine shop and I'm starting assembly. In looking at where the dipstick enters the oil pan, it looks like there are two metal plates on either side of the hole in the pan that are pop riveted together. It appears there's a cork gasket between the inside plate and the pan.

The gasket looks pretty well shot, but the pan is in otherwise great condition. Is there anywhere to get a new one? I've tried searching and didn't come up with anything. I don't think that the gasket leaked, but the whole motor was oily when I pulled it. Since this is in a van I have to pull the whole motor to get the pan off (and I'm not looking to do that again any time soon!).

If gaskets aren't available, should I drill out the pop rivets and use some RTV and new pop rivets to put it back together? Or, should I leave well enough alone?

I would drill out the rivets while you have easy access. You could make a gasket with a piece of gasket material available at your auto parts store rather than use RTV

Can you drill the block for a dipstick and block off the hole in the pan?

Why would you? He has a factory pan with the dip stick in it already. Everything is already where it needs to be.

Just do what Shorty mentioned drill out the rivots and then either use a little rtv/gasket maker ( not huge globs ) or get a sheet of gasket material and cut out a new gasket. Then get some nuts and bolts to replace the rivots. Just make sure to use some loctite/thread locker on the bolts when you reassemble it. And you will be all good.

If you can get everything super clean you could get it brazed or soldered and never have the problem again. Luck
