Daverse 175 Posted September 22, 2013 Report Share Posted September 22, 2013 I think some people make like an adaptor for an air line that blows air into the spark plug hole and keeps it under pressure so when you take the springs off the valces dont fall into the cylinder. Would be miles easier just to take the head off though imo. Have you had it on vagcom for the misfire? Sent from my GT-I9300 using Tapatalk 2 Link to post Share on other sites
Lukey. 381 Posted September 22, 2013 Report Share Posted September 22, 2013 Putting each cylinder to TDC will help too Link to post Share on other sites
leespiro 9 Posted September 23, 2013 Author Report Share Posted September 23, 2013 theres no error code on the vag-com Link to post Share on other sites
VR6Pete 1,455 Posted September 25, 2013 Report Share Posted September 25, 2013 Could be possible. I purchased some schimmel heavy duty valve springs and retainers ages ago, never got to fit them though, would usually have an idea if you have valve spring bounce on the rolling road, have you got graphs?

GordonC 20 Posted January 26, 2014 Report Share Posted January 26, 2014 I've heard of some people puting some rope into the cylinder through the spark plug hole and rotating the engine slightly to pack it all tight. Never tried it myself it was easy enough to just take the head offVR6 Loonibuggy Santa Pod 2014 ! Link to post Share on other sites

VR6Pete 1,455 Posted February 2, 2014 Report Share Posted February 2, 2014 If your head has for more than 80k then defiantly do valve guides too. Club Chairman Link to post Share on other sites
