I am ready to marry up the oil pan to the block on my 26 Tudor. What do you all recommend for gaskets? Should I use the paper gaskets, the silicone based products, or both? Thanks, Rand

I have found the repop paper gaskets leak because they do not compress well. I make my own from rubber impregnated cork sheets using a repop for a pattern.

If you want no oil leaks clean the surface very Clean with a solvent like Naptha and use ULTRA Black from Permatex. Some will say here that they have had a hard time getting things apart but if you use a thin putty knife in between I have not had any problems and no leaks.

Don't substitute for just black rtv it's not the same

Thanks for your opinions and suggestions. I will weigh both methods and come up with one that I think will work for me. I have used ULTRA Black before on oil pans on other motors I have rebuilt over the years on modern cars and it does seem to work great and with that method you don't have to make new gaskets. You just have to ensure that all surfaces are really clean before you start spreading the sealant. Rand

In addition to the good advice above, make sure the pan is straight. It will be easier to seal.

Thanks John I'll check before I bolt it on. Thanks, Rand

Over the years the area around the bolt holes gets pulled up, make sure they are flat also.

Use Permatex no.II non harding. I used silicone and had to redo.

What Mark G said is probably the most important thing to do to avoid pan leaks. All the good gaskets you can buy wont work well if the pan bolt areas aren't flat.

Phillip, That's exactly why I prefer the Ultra Black. It'll outseal / perform better than any old type #2. I've been told that's what is used today on many OEM cars. You don't see any leaks on a new car anymore.

The old sillycone seemed to peel off and not adhere very well at least on places that I have seen it used.

I use repopulate gaskets with a beer of blue rtv gasket on both sides

Bob,??? Do you look at your posts before you send them? Not trying to be an a$$, but many of them don't make much sense. What are repopulate gaskets with a beer of blue rtv? Just sayin'. Dave

David, Once you get a "smart" phone with autocorrect you'll understand Bob's postings
:-)

(maybe repurposed/reused gaskets with a bead of blue rtv?)

Most likely "repop gasket & a smear of" Rogers right until you check the auto correct or voice text before you send some really crazy texts or messages get sent. I know.

I like the paper gaskets with RTV on the none machined surface. So I goop up the pan, install the gasket and the attach to the block without goop. Same for the hogs head. I also use the felt gasket on the head smeared with RTV on all surfaces. Do not cut shorter, push it around until it fits. Works for me on about 50 engines....
Word of caution, if you delete the magneto and the magneto coils, make sure the bolt holes don't go thru the block. That has been the only serious leak causing me a warranty problem...

Yeah wife had auto correct going and repo paper gaskets came out repopulate with beer???? Go figure
I also set the preview post option here sorry
Had good luck with blue rtv and paper gaskets
I use rubber sided washers on the pan bottom after making it flat as I can or cork when I can find it

I use copper washers on the inspection pan, solves all the drip problems. Buy from Mcmaster in bags of 50.

Bob, that makes sense. I didn't think about that. I have seen some really weird things from the auto post thingie. Nice to know it knows more than we do<g>. Dave

The washers with a rubber insert work very well and I think are available from the T vendors.

Others have simply used a piece if thread with sealant wrapped around the bolt.

Naptha probably works well for a wipedown, but is hard for me to get. Acetone is another alternative that works really well.

Skip this step at your peril!

The washers Gene mentioned are called sealing washers (5/16"). I use them on the pan's inspection plate. They are available at bolt & screw stores and sometimes at big-box stores.

Why can't they make cork gaskets?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Adam Doleshal on Tuesday, August 25, 2015 - 10:37 am:

Larry, Most likely because they shrink and don't fit right if they are on the shelf for a long time. And probably because the material costs $0.01 more!

If gaskets has shrunk, put them in water and let them soak - I learned that lesson from older friends, we should be able to pass that lesson on :-) (or it could be written in the catalog)

Once and awhile I can get cork sheets from my contact at Napa I just make new ones from the paper ones


Top of pagePrevious messageNext messageBottom of page Link to this message  By Larry Smith on Thursday, August 27, 2015 - 10:43 am:

Not a gasket, but they sure work. Buy a box of Dorman 5/16" copper brake line washers for the bottom oil pan cover, and use them on those bolts. Your drips from those bolts will go away.

Don't know if I'm too impatient or what, but I have NEVER gotten a shrunken cork gasket to expand by soaking it in water, no matter what it was for. I have tried that trick many times over the last 50 years, even letting them soak for a few days, never worked. Maybe they were just too old? Dunno. I much prefer the paper type, always have. JMHO Dave

David, maybe it was paper gaskets I used the trick on then? it was a '38 Chxxy with rubber gaskets for the pan that failed - I found old nos pan gaskets at a swap but they were too short. Lengthened to fit overnight in a bucket of water. Can't really tell what exact material they were except it wasn't rubber as those who were there before (it was 25 years ago) - and it worked :-)

There's a reason why millions upon millions of cars used oil pan and valve cover gaskets made of cork.
