Valve Spring Tool -

Hey Rufrob - There are many inexpensive, generic valve spring compression tools available that will allow you to disassemble your 928 heads. Here is one -

While working to breath some life back into a 1988 928 that had been parked for years I've even replaced a set of crusty/decomposing valve stem seals while the heads remained bolted to the block. I don't recommend this but at the time I was trying to determine the initial condition of the motor - Although the cylinder compression was good - it smoked like a diesel tractor pulling stumps when running.

1 Disassemble and remove the cam assemblies -
2 With the spark plugs removed place a soft rag (string attached) into a cylinder
3 Use the crankshaft bolt to slowly bring the piston to the top of it's travel
4 Attach the valve spring compression tool to the top of the head
5 Remove one of the valve spring retaining assemblies of the selected cylinder
6 Install new valve stem seal
7 Repeat for each intake and exhaust valve

Good Luck - Michael
