Was looking for the best DIY cost effective intake valve cleaning method while still being really efficient. From my understanding a DIY walnut blast seems to be a popular one but id have to buy all the tools for it which wouldn't be a problem. Just seeing if anyone had some insight about an easier method maybe cheaper method. Thanks
Tomorrow I am planning on looking at a 2010 335I X Drive E92 with 35k miles. For 12 grand that has been posted for 20 days. The price seems cheap to me like a very good deal and the longevity of the post is the only thing I’m batting an eye at looking for some advice because in the post he that on startup when cold it idles rough due to carbon buildup on the intake valves, which I feel is very believable if it hasn’t been done and its whole life, but at the same time, it makes me bat an eye due to the low price and time posted. I’m planning on reading the codes and looking at the car very closely. Any advice or thoughts? Does this raise suspicion?? Thanks
