As the title says the timing chain is scraping on the front cover. We've changed the timing chain and gear and put on a ZZP Double thick gasket and it still scrapes. When we tore it apart to change the timing chain gasket because it was leaking it didn't scrape so I have no idea why it is now scraping, the noise isn't coming from anything belt related either, What could it be scraping on? I'm clueless.
