I have read a lot about the carbon problem and fix for the N14 engine. Here is what I am thinking about doing to fix the problem. Has anyone tried any one of these. 1. eases but most expensive. Meth (Dave is all smiles) 2. Mark already has a catch can from the back PVC to the turbo so I could add a second one that goes from the front PVC to the intake. This is the one that causes the problem. 3. Vent the front PVC to the atmosphere through a filter (K&M sales them) or like in the old days run the hose into a old oil can with holes in the top Then block the hole in the intake so no more oil is sent to my valves. I don't want to hear about venting to the atmosphere hurting the environment. Al Gore did more damage when he started his jet to fly to the climate summit then the Helmet will do its whole life. Also maybe I should ask Jan about the Meth sense he did the tune to see what els I need to change. So Metalman? Also what is the best system for Meth?
