Hello All Civic Enthusiasts,
I have a stock 2007 Si with 220k on the K20. The car runs really well and is in good shape, but I hear pinging going up hills at times doing about 45mph. I'm thinking if I need valve adjustment. I do know I need a new knock sensor. The local shop I take it to told me I also need a new exhaust system. I'm overseas in Germany and I need to order what I need. I was thinking about installing some headers. Basically if you all could tell me everything I need to order for the headers/exhaust system, that would be a great help to me. I just don't have lots of time to research it all myself. Should I rebuild the engine before doing mods? If I do mods, what order should I do the mods.

Thanks for answering my questions and appreciate your time to answer my questions.

Pinging is destructive to your engine and should be the first thing to be corrected. Another name for pinging is “knock” so the knock sensor may need to be replaced. With a manual transmission, going slow up hills in a high gear can cause pinging/knock. Down shifting to a lower gear may help. Low octane fuel can also cause pinging if the engine was designed for high octane fuel.

Thanks for your response. Yes, I do run the highest octane fuel in the car at all times, and I do down shift going uphills. the 'knocking' doesn't seem to happen all the time, so I can only assume the fuel is not the best that the supplier provides at all times. I'll replace the knock sensor as soon as I can and see if that fixes the issue. Thanks again for the reply.

Welcome! Were you able to fix it?
