From the posts I've read on changing oil pan gaskets when changing the motor mounts, now is the time. I've got the motor mount job started and will finish tonight and tomorrow night.

For the oil pan gasket, which Yamabond product are people using? I've found Yamabond 4, 5, 6b, 6s and 7. From reading the product info, it looks like 4 or 5 or maybe 6s, but not 6b or 7.

Thoughts please?

I used Yamabond 4.

I did too, after reading about it here. I was not impressed by it. It seemed to dry real quick and did not seem very sticky. But i started with and used it. I have some K&W copper gasket sealing compound (meant for all gaskets, copper in it) and it sticks like, like glue. I used it on other places like spider to block gaskets.

Forget the Yamabond and traditional gasket and contact Shocki (Texas) for the reliagasket he recently promoted.

I installed my cork oil pan gasket without any sealant, and with great results.

That was over two years ago and I still have a perfect seal. Knowing the ideal compression of the gasket material is the key to a leak free, durable gasket. Sealant can work great, but is really not necessary on the oil pan.

Even the silicone gasket sold by Realgaskets ( http://www.realgaskets.com/ ) can be overcompressed.

Since you can't use a torque wrench on every bolt, the best solution is to count the number of turns required to give the optimum gasket compression. You can search the posts to find the procedure I used.

FYI...Honda also makes a similar product....Hondabond. I couldn't find Yamabond anywhere, but a local motorcycle/ATV/jet-ski shop stocked Hondabond.

Lets see. yamabond, hondabond.you forgot there is a suzukibond too!..Maybe we could get porsche to stock porschebond..then we know were using the right stuff...
really though yamabond 4 has worked fine with me and yamabond 5 will dry to a harder form. Ive had good results when the bolt threads were coated.

Roger and I did the gasket on my GTS 2 weeks ago and the job requires a lot wrenching but otherwise, no problem.
I was thinking about Hondabond or Yamabond before just to seal the pan permanently. If you want to know more about a different solution read this https://rennlist.com/forums/928-forum/237875-first-928-oil-pan-sealed-with-gasket-from-realgasket.html or search for Realgasket.
The realgasket is now sold by 928 Specialists and is a big improvement over cork. I use the material on my 911 Targa since 5 years. I remove the valve cover gaskets every year to adjust the valves and re-install them with no problems. The silicone used on the Realgasket is guaranteed for life, seals even a warped pan, withstands up to 400 Fahrenheit and is re-useable.

Just for info: After I did my motor mounts I tightened the oil pan bolts and the oil pan leaks stopped, even with the old cork gasket. But if you look at the pictures cork is still not the best material to use for a long term fix.

Thanks for the info. I'll call around to see if I can find Yamabond or Hondabond or Suzukibond and may call DR or Jeannie for the silicone gasket. The motor mount job is proceeding about 2 hours per night. Should have it done on Friday, then figure out how to support the engine from above to do the pan gasket.
