Best Oil Pan Gasket

I have an oil leak that is comming from the rear of the oil pan, appears to be the gasket. It has a one piece gasket from Fel-Pro. It's a fresh rebuilt
SBC 350 with a Moroso oil pan. The engine was broken in on the dyno, and it did leak in the same place as now. The builder said he put a new gasket, started it up again and it didn't leak. Now the engine is in the car, with only a couple of miles on it, with this leak. I can say that I have no other leaks anywhere else. I'm thinking of doing the gasket change with the engine in the car by lifting it for clearance. Not happy at all at the moment! But I have to get it done. I don't want to go with the same gasket if it's going to leak again. Any suggestions on gaskets would be appreciated. It's a '69 block with a stock front timing cover. Oil pan is also studded, which may pose some problems getting the oil pan out. Thanks in advance, if I left anything out, please let me know and I will provide the needed info.

Re: Best Oil Pan Gasket

those one piece fel-pro gaskets usualy work pretty good. you do have to have the surfaces completly dry to get a good seal and dont use any silicone. you might just try a multi piece cork set .

Yeah, thats exactly what the builder told me, they were good gaskets.
You mention no silicone as well, when I get in there with a light I can see silicone between the gasket and the rear main cap. Seems like he did this to keep the gasket in position, while installing the pan. What might be a good adhesive to do this when I get in there to fix this?

I have never liked the Felpro one peice pan gasket and the Corteco 16635 is a much better gasket!!!!!!!!!

Re: Best Oil Pan Gasket

Both felpro one piece oil pan gskts that i used failed with two different pans..albeit under the timing chain cover.Never again for me.Went back to a victor cork and rubber with rtv in the corners and dry as a bone.

Re: Best Oil Pan Gasket

I too had bad luck with the Fel-Pro 1 pc gasket for my 350 and now my 400, leaks at the back and it wasn't the main. This time while I had to to do a rebuild of the 406, I put in a Victor Reinz 1 pc from CNC Motorsports.com and I have to say I really liked the way it made compared to the Fel-Pro and the material it is made of is Victo-Tech Rubber instead of the silicone type. I was able to put ultra black around the ends of the timing cover and the back end of the pan as well as the corners as suggested. Though I have not had the car running yet, I feel better about the way it went together and pretty confident that it won't leak. I'll know hopefully by the end of the this weekend.

Re: Best Oil Pan Gasket

I've had bad luck with them too with my car. I've done what your talking about doing 3 times, and it sucks. I finally had to pull the motor to get it right. I put it back on the dyno to ensure that it wasn't leaking before I put it back in the car the last time.

Re: Best Oil Pan Gasket

Dang. I was gonna say to use the Fel-pro one piece and that I've had good luck with them until I read how many of you have had problems with them. I always used a little silicone in the corners and they sealed fine.

Re: Best Oil Pan Gasket

I put a one-piece FelPro in mine and it didn't leak for the thirty minute run. The thing to be sure of at the rear is that the little recesses are completely clean and free of any old RTV and degreased. Nothing sticks to old RTV, not even new RTV. The gasket has two little tabs that go up into those recesses and there along with the front corners at the timing cover should be the only place RTV is needed on the one-piece.

I did mine with the motor in the car and actually had to jack the pan up onto the motor to get the bolts in. The two ends of the gasket had to kinda stretch around the round parts on the front and rear. That coupled with the thickness of the gasket made for a big headache trying to get the bolts in while holding the pan up by hand.

Re: Best Oil Pan Gasket

Thanks to everyone for the information and feedback! Looks like I won't be going with the Fel-Pro one piece again. Where can I get the Corteco gaskets from? I haven't done a search for them yet. I can already imagine my frustrations under the car taking care of this problem. You guys think I should pull the engine? Grrrrrrr!

Re: Best Oil Pan Gasket

They make 2 different one piece gaskets for the sbc's, depending on which year model.
I'm beginning to wonder if some of you recieved the wrong ones.
Mine works fine, your supposed to apply a small ammount of silicone on the corners by the timing cover and rear main.

Re: Best Oil Pan Gasket

I've had no problems with Fel-Pros 1 pc gaskets. I have one on the oil pan and both vlave cover. I'm also using the blue Fel-Pro t'stat gasket.

No problems at all.
