fair point made , but there all new (apart from lower tensioner) , no need to replace . everyhting is spot on execpt the pikeyed guide bolt . we replaced the upper hydro tensioner as part of the course . if it was a customers car it would be getting the full works treatment . for our first chain change its gone very well !! plus side - got it back together today and its all running shweet , timings spot on . pulls and drives like a Vr should !!! fookin well that is . just theres a problem with the cooling sytem now . its running hot and fans arnt going off . its not headgasket . suspect
