Trying to find a replacement oil pressure spring to install during my next oil & filter change. Thought it would be wise to check the factory spring for cracks, then thought while I'm in there good idea to replace OEM with the better spring. Seem to recall LN has one, but damned if I can find it on their website. Anyone have a link for the LN spring or know of another source?

 

Do you mean an upgrade for 99610712753 in the pump assy.? That is the oil pressure relief piston/valve (+spring ) . There is also a piston upgrade available for the pump.Slightly different chamfer & profile.
These links may help you ?

The oil pressure relief piston and spring that Mr. Gelb listed at Auto Atlanta have been upgraded, and the upgraded part numbers are listed. It would be wise to use the upgraded piston and spring. It would not be wise to deviate from the upgraded parts. IMHO You might also check Sun Coast Porsche or even your local Porsche dealer.

Yes. Thanks for the clarification and links - very helpful stuff.
