did heads on an 02 outback h-6....there are 12 of these in the head kit...anyone know what these are for?

Kinda looks like a grommet for a valve cover bolt.

thats what i thought at first...but they dont quite fit right, and there arent enough of them, and there werent any there when i took the valve covers off...i know there usually are...but the h-6 must be different.

Hopefully someone who knows the H6 like the back of their hand will chime in. It looks like the same washer they use in the bottom of the power steering pump reservoir on the 4 cyl cars. Kinda figured it might have something to do with oil, but I don't know that engine very well. (at all)

head bolt washers ? 12 wouldn't be enough would it, 16 bolts, right?

 

are they metal or fiber or plastic?

just like a plain flat washer with rubber in the middle..

Could it be a sealing washer that goes between the timing cover and block & heads?

what kind of head gaskets are you using?

my 95 came with those. Theyre good for filling up a corner in your tool box

what kind of head gaskets are you using?

 

it was a set straight from the dealer.

Doing reverse engineering, there are only 4 items that have 12 units.

ie: seals for exhaust/intake valves,circlips and cylinder block washers, which I assume (never assume) go on the head bolts.

 

O.

maybe some of the head bolts are through oil galleys? :-\

Part numbers help!

It's number 6

They go on some of the bolts that hold the block halves together.

 

And they use them in EVERY engine. http://opposedforces.com/parts/info/11034AA000/
