Hi !

1981 928S Euro,

Spoke with the machine shop today and the heads and towers look better than expected, no corrosion or pitting seen near the fire rings, cam tower to head surfaces are true (!!) , head to block surfaces look flat and otherwise untouched. She is going to need valve guides and valves.

I need to purchase gaskets, and I see the VR set is available..
But aren't there other gaskets that are available which are upgraded/improved for certain areas? I am specifically interested in the cam tower gaskets, as these were the source of my original problem...

Any advice or opinion would be respectfully appreciated. Thank you for your time and insight.

Greg at precision makes a super set of cam tower gaskets. A must for sure

i would go stock on the gaskets for the heads and cam towers. the new gaskets are better than the ones the factory used 35 years ago!

Just fill with distilled water and you are good for another 30 years!

ahem.. Dont you want to buy an old 5 liter to put under your new heads? WYAIT

I recommend Gregs cam tower gaskets also. Buy 3, you'll inevitably rip one. And he sells them cheap, in packs of three

Sorry Mark but this is a two valve and everyone else realizes that factory cam gaskets are a poor choice. And seriously only distilled water ????? very irresponsible suggestion....in my opinion.

We stock the GB cam tower gaskets as well as all the other gaskets needed. Also the full engine gasket kits as well.

I trust that was a joke with the smiley face!!

Count me among the dunces, then.

The factory gaskets are fine as long as the tower and head are clean and true. Use the torque pattern and a torque wrench. I suggest that if it's not leaking now then the stock gaskets will be fine.

As to the OP....

Getting the kit is the cost-effective way if you're truly doing a full rebuild. Get the right kit by P/N: 928-100-901-01 And double check that. The kits contain parts for multiple years and FI systems. A bit confusing as they're not labelled so there'll be parts left over. The kits go exactly by the parts listed for them in the PET.

You may want the silicone oil pan gasket.

Don't goop anything unless it really, really needs it. (Pitting, damage, etc.) The exception is the stock pan gasket that needs your favorite sealant on both sides. I use black RTV. Some like Yammabond. Some use bacon grease.

One of the interesting things about asking for advice is that you get both kinds....good and bad.

The trick is trying to figure out the difference.....

While I make and supply many different products for the 928 in.order to solve problems, I only supply one gasket.

....And I didn't come up with that part because the stock one worked perfectly!

Can I install a stock cam carrier gasket and make it work? Sometimes. Can I guarantee that it isn't going to split and start leaking in the future? Not hardly.

Can I install my gasket and make it work? Absolutely every single time. Can I be sure that I will never have to redo this gasket because of leaks? Again, absolutely.

Guess which one I use when I build an engine.....

And then on the other hand, I throw silicone pan gaskets in the trash and use the stock gasket....because I have better results with the stock gasket.

Life provides you with a continuous supply of choices. Go back and read one story about someone replacing leaking stock cam carrier gaskets for the second or third time and ask them what their choice is (there's lots of them on this Forum) and make your own choice.

After dealing with the absolutely crap factory 2v cam carrier gasket I won't use anything except what Greg has produced.

As glen says though, as long as things are true and clean, the stock stuff will work.. we are talking cam carrier gaskets.... its a real thin gasket, and I think its been upgraded by Porsche over the years. again, I don't know what SSF supplies Anderson, (or Me) but it looks a LOT better and MUCH difffernent than the gasket I scraped off the car for 6 hours on my original 4.7 upgrade back in 1997. 6hours of back braking scraping... should have pulled the engine!!! UGGGGG.....
anyway, the hard part is getting the surface clean, and if you cant.... maybe Gregs gaskets if he sells them is the way to go. head gaskets however, good to go stock.....the high performance gaskets need procedures different than the manual says for torqueing and the consequences for not doing so are not good! (cometic vs stock Porsche 928)

No. Don't waste your time with the stock cam carrier gasket.

I am so glad with this info about the cam tower gasket. I didn't know there was a better alternative than stock. I'll pm Roger. Thanks

A dead Sith uses an inferior product and advocates the use of same.
