Pics of the gaskets would be helpful. The washers sound like they would go under the head bolts..Might want to check the PET to get the right size and number or washers required. You may have lost a couple Hope this helps some.

I know this answer is going to drive you crazy but the Reinz kit contains more items than you will require. This is because one kit is used to span several generations of engine. I suspect the cost of the extra items in the kit is balanced by their having to carry fewer different kits in their inventory. But I always have items left over from a Reinz kit.

As Tiger says, get the PET and use it. (Available on-line from Porsche - free!) In many cases, the PET with give you sufficient dimensions to make an ID on the washer you need.

The answer also depends on the model year of car/engine you are working with. The new 4 valve/cyl engines will use different items than the earlier engines. You should go into your Rennlist profile and edit your signature to list the car you own. Saves us having to guess

If you have a 2 valve engine, I will suggest that the little white one is going to find a home in the back side of the cover that goes at the end of the camshaft housing, assuming you dis-assembled that piece. There will be a black or the red Oring at the same general location. If all you did was remove the head, some very heavy washers (they are pretty obvious) go under the nuts for the cylinder head bolts. There should be 10. There are 2 extra, smaller bolts at the front of the head that are one size smaller that use washers. The allen head bolts that clamp the camshaft housing to the head generally have captive washers but that is the only place I can think of where you use an odd number of washers. There are of course some washers under the nuts that attach the exhaust manifold. They are generally pretty dark and rusty looking, due to the heat. There are some obvious large thin aluminum washers that go under the plugs that go into the top of the camshaft housing.

If you've got a 4 valve engine, I'm the wrong guy to ask!

Good luck!

white goes between the camshaft housing and cam gear housing.

black o ring goes next to white.

brown o ring looks like throttle body seal.

metal washer, guessing it's for an m10 bolt based on diameter? Can't think what its for though.

Thank you all of you.

The metal washer is for the exhaust.

Luckily I took some photo before disassembly.

What is PET ?

Link please.

Thank you.

Google "Porsche PET"

First link that comes up should be "Porsche Classic Genuine Parts Catalog". Open that link.

About 1/3 way down the page, there is a menu box for the various catalogs. Use the selection box to select your make and model.

Once you get the one you want opened up, save it as a pdf to your computer. You will use it a lot!!!

And I am sure that PET is an acronym for something in German but I couldn't tell you what it is.

Of course it is... the VAG gang doesn't do anything without a good reason.
