Default Replacing oil pan gasket

Had My engine out over the winter so I could clean up the subframe and repaint engine Bay. So while it was out I decided to replace the oil pan gasket, The Dumb ass that I am Did not realize that I needed a oil pan gasket with a thick front seal.... there is a one peice rubber gasket in there now .... I am hoping I can drop the pan enough to pull out the old gasket & slip in the new one ? Has anybody done this before ? The Vehicle in question is a 71 Nova with a small block..... Thanks

Dude your going to play hell doing that in the chassis. Can it be done? Yes but its not worth the cussing it will take. You should be able to have that motor out of the car and on a stand in about an hour. Makes life a lot easier.jmo!

X2 and if you stuff it up and it leaks you'll be pulling the motor any ways .

Old Indian trick, used many times on Ford trucks.
The one piece rubber gaske stretches pretty good. As long as you can drop the pan enough slip the gasket over the outside of the pan. To install new just work it over the outside and get it into place. Just clean the pan and frame good so if it rubs it won't pick up dirt. If you want you can just cut the old gasket and slip it out.

overall, there are a number of so called shortcuts..

but when you only have one chance and only one time to do the job...better just pull out the engine and turn it upside down and replace the seals / gasket..

the chance is less than half that doing it in the car will seal up properly...
as known,,..many have had sucess...but just in the fact that you have to ask, tells us that you have not tried it and failed or had sucess...
in fact, I HAVE done it and not leaked...but i have done it 15 times..and half of them eventually leaked...
..maybe after a few hundred miles no less..but still had to pull it out and do it up on an engine stand.

Were talking sbc here, its a one piece gasket that has to be worked aroud the oil pump and thaat ain't gonna happen in the chassis. Good luck at what ever you do!

Take the engine out and do it right. If you really want to do it without pulling the motor unbolt the motor mounts and lift up the engine a couple of inches

OK, listen to this......yeah, go ahead drop the pan as far as you can, work the gasket around the pan, bolt it back up and fire that baby up no problem Hows that for positive.

Now, after you fire it up, and it piss's oil all over, either 5 minutes after start up, or within a week, now you can pull the motor, put it on a stand, carefully remove the pan, keep everything clean, and very carefully install the second brand new gasket. Carefully inspect your pan flange to POSITIVELY INSURE it does not have a distorted lip, and carefully reinstall it with the proper sealant, and properly torqued fasteners. Do this while trying to ignore your own foot constantly kicking your own azz the whole time, for trying to cut corners and costing yourself twice the time and money for two gaskets instead of one........when you knew better the whole time.
Good luck with this process, (seriously ) and dont do this in the middle of the night when you need to be to work a couple of hours later, cause it still wont end pretty......

I wouldnt pull the motor to do it. Just unbolt your mounts and lift it as best as you can. Worst case, when you lower the pan you may have to unbolt your oil pump pickup. Are you guys really pulling motors to change pan gaskets?? That would make one hungry flat rate mechanic.....
