Yikes! Need Guidance !, Spring Washer on Rocker Shaft Broken ! Options

[Beebo Kanelle]

My engine developed a tapping noise so, I pulled the valve covers to check the clearances.

I was greeted with items shown in photo 'Big Problem 01'. It turns out that the spring washer that controls the rocker arm geometry has failed and the rocker arm has moved as shown in 'Big Problem 02'.

My temporary solution is to remove the rocker arm assembly and replace the spring washers.

Are There any problems with this solution?

Does anybody have the specs for these springs washers?

Thanks in advance.

Now it gets weird...

I went to the local VW/Porsche dealership to order the wavy spring washers and was told the were discontinued in 2009. Ok, no problem - just get on the interwebs for a p/n113-109-437 - (I got the p/n from the dealer).

Received them and it turns out that the ID = 18.5mm and my old rocker arm shaft washers have a ID = 20.6mm !

I suppose that there are two types of rocker arm shafts ?

Can anybody clarify my dilemma before I jump off a building?

On top of everything else, its flooding down in Texas and I really want to get this solved.

Thanks !
