I am sorry for hijacking this tread, but does the piston and spring update applies to the 3.4 987 as well..? Thanks!

You would have to check that with a good part department; at some point, the retrofit parts became the parts in the car from the factory, but that would require checking the VIN number to be sure.

Yes, and as the cassette shares the metal gasket with the water pump, it is a good time to replace the water pump and the oil pump drive shaft which is an investment cast piece of crap that is known to snap. LN has a chrome moly replacement for about $20.

About to replace the valve/spring on mine. After installing is it recommended to "prime" the engine before starting to build oil pressure? Or is it ok to start immediately after install?

Gents,
Is there torque value reference anywhere for the oil pump pressure relief spring and piston retaining plug.....it much like a drain plug with a crush ring.
I am just changing the 986 stocker to the updated spring (996) and piston (997)...yes late to the party.
I can post an image if the item the part(s) I am referring to are not clear.

Hats off to those able to do this in the car. Maybe a lift gives better perspective. It is tight up in there. Next time I have the firewall cover off I will look at ....but wow!
