There is a lot of discussion about oil pan seals. Cork, which hardens and shrinks, and eventually will need retensioning the bolts but still leak... Or maybe the silicone gasket that was introduced a while ago? Buy the latest from 928sRus (Roger)? Or maybe use the material from Victor Reinz and make your own like Ake did:, see pics below
Carefully and gradually torque the bolts to 7Nm. That should do it.
If you want to make your own oil pan gasket, it helps to have a template that can be used to cut the outline and holes.
To make this easier for those who just want an oil pan gasket....
I've attached to this email printable versions of the oil pan gasket drawing. In Adobe Acrobat (PDF), Adobe Illustrator (AI) and Adobe Photoshop (PSD) formats in a ZIP file. And the PDF file unzipped for easier downloading. They are scaled to the correct size paper. You have three options:
1) Give the file to your local print shop (Kinkos, FedEx, poster/banner print shop, etc). Have them print it out in full size.
2) Look for an online printing service (anywhere that can print blueprints or posters/banners, etc).
2) Print it out on your home printer in full size. It will print it out on multiple pages which you can cut and tape together.
These are the settings that I used when printing the PDF version to get the correct size, which can then be taped together:
Once you have the printout, make sure to carefully measure the gasket template drawing. The length of the drawing should be 598mm (23.543") and the width at the widest part should be 332mm (13.071"). Within a few mm is fine.
You can now use the printout as a pattern for the gasket. Either cut the template out so you have a paper "gasket" to use for the template, or lay it on your gasket sheet and cut through the paper and gasket at the same time. Either method will work. The fastest method would be to lay the uncut template down on the gasket sheet and then use a utility knife to cut through the paper and lightly score the surface of the gasket sheet. Then, remove the paper and finish cutting the gasket out, using the scored lines as a guide.
Once you have the gasket cut out, put the paper template back down on it and mark the centers of the holes by whatever means you prefer. An awl, the tip of a razor blade, the tip of a small drill bit, etc. Then, remove the paper template and put your holes into the gasket. If you decide to put the holes in with a drill, make sure that you place two pieces of wood very close to either side of the hole to hold the gasket down so it doesn't twist or spiral up the drill bit. If you use a leather/gasket punch (something like this Amazon Amazon ), then make sure to only use it on 1/16" or thinner gaskets. Thicker gaskets will split when using a hole punch. 1/16" may still split, so it's marginal. Best to practice your holes on the extra gasket material.
For the gasket sheet, you can get it wherever you want, but if you want "easy", just order it from here: https://www.gallagherseals.com/kling...-material.html
You can order it big enough for one gasket (30" x 15") or for two gaskets (30" x 30")
For thickness, you have a decision to make:
-1/64" will be very easy to work with, but also so thin as to offer little benefit in the way of compressing and molding to irregularities in the pan flange shape.
-1/32" is better, and still easy to cut, and I wouldn't go thinner than this, personally. This is also the maximum thickness that will reliably accept punched holes without splitting.
-1/16" is a good compromise in thickness versus ease of cutting. It will take some effort, but very doable.
-1/8" will most closely match the OEM cork pan gasket thickness after it is compressed. But, this will be difficult to cut. I found that a few strokes with heavy pressure from a utility knife with a fresh blade, then turning it over and finishing from the opposite side worked best.
Whatever you select, I recommend dressing the gasket with a gasket dressing. Something like Permatex Ultra Black or Drei Bond. You want a thin coating on the oil pan flange and another thin coating on the "top" of the oil pan gasket so that you end up with a thin coating between the pan and gasket, and between the gasket and the block. Thin means that you're not making a gasket with the dressing, you're just making sure everything has a thin coating to ensure that any irregularities are filled in.
For a cutting tool, I recommend a fresh blade in a sturdy utility knife for the most precise cut. I tried a wheeled blade and it just didn't work nearly as well as the utility knife. I also tried heavy shears but the hinge bolt gets in the way after a couple of inches.
By far, the easiest way to cut the gasket is to use good quality tin snips. And if you have the left/right hand curve versions, they help a lot with the curves in the gasket. This is a very easy method to cutting the gasket, but the edges won't come out as perfectly as if you use a utility knife. If you use tin snips, you'll want to clean up any burs or irregularities with a utility knife.
For the 1/8" thick gasket material, you can try the score and bend method. This is where you deeply score the top of it, cut perpendicular lines with tin snips, then bend the resulting flaps backward. Then, use a utility knife to cut the "hinge" from the back side. Sort of like drywall. If done carefully, it will turn out fine with minimal cleanup of the edges needed.
1) Print out the template.
2) Trace the template onto the gasket sheet (either cut it out and trace with pen, or score the gasket sheet with a utility knife through the paper template).
3) Cut the gasket out.
4) Drill/punch the holes.
