valve noise ?

I'll just throw this out there for what it's worth. I used to get cold start-up valve train noise on my minivan with 3.3 and I think IIRC on a previous 318. Then I saw an oilfilter comparison on the EEK site. There was an article by just a regular guy like me who cut different oil filters apart, compared the internals, and concluded the Fram had a problem with the anti-drainback valve or something to that effect. I'd been using orange Frams exclusively on all my vehicles because S&M had the sticker on their fender. Well I bought a standard Purolator and tried it. Instant fix, no more noise on start up so that's all I've used for the last 10 years or so. IIRC he said Wix was good too but the Purolators are easier for me to get from Advance Auto Parts. Might be worth a try.
