OK seafoamers, I just did a seafoam treatment on my vx. I used the brake booster vacuum line to sip up about half a bottle. I was expecting smoke, which there was, coming from my exhaust manifold!! I thought maybe I have an exhaust leak at the manifold, but no, I can see something (I'm assuming oil) running down over the manifold! It never did this until this seafoam treatment. And it happened during the treatment so I blame the seafoam! Could this stuff have eaten away my valve cover gasket or head gasket??! Any ideas on what it could be? I'm hoping this attempt at a little preventative maintenance doesn't end up costing me big time..
