Well I thought I had licked it but it keeps coming back.
Every so oftemn, I repeat...very intermittently, I hear a distinctive valve tapping coming from 98 V90. It seems to occur after I put the car in neutral after a good long run...at least that's the only time I really hear it.

So far I have tried Marvel Mystery Oil: hard to tell if it does anything
AutoRx treatment: save your $25
Techron fuel system cleaner: hard to tell
Redline Sl-1 fuel system cleaner

I guess additives/treatments just don'e work. What is this and why do I hear it only intermittently with a hot engine and how do I get rid of it and...do I need to get rid of it?
