gerg 10,871 Posted August 4, 2013 Blown piston seal on top gear? Stuck valve in valve body? Autos are never an easy fix so I'd take it to an auto place. As the saying goes: if the job was easy, there wouldn't be a trade for it. 1 revhead reacted to this Share this post Link to post Share on other sites
Mr Polson 10,214 Posted August 4, 2013 Isn't something to do with the vacuum thing C4s have? (I think it's c4s that have that). Judging by what I read on Google it could most likely be valve body related. Share this post Link to post Share on other sites
