MarkGolf 6 Posted December 19, 2011 Report Share Posted December 19, 2011 Hi all.I'm looking to replace the head on my VR6... If I remember rightly, the OBD2 head has some sort of hole in the front of it.. I know my OBD1 head doesn't have this.What is it and can it be blocked off so I can fit it to my corrado engine without issue?Thanks Link to post Share on other sites
Pearsy47 1 Posted December 19, 2011 Report Share Posted December 19, 2011 do you want a obd2 full rebuild head?? Link to post Share on other sites
MarkGolf 6 Posted December 19, 2011 Author Report Share Posted December 19, 2011 if it will fit onto my engine, yeah.. I just question that hole in the front of the head.. Link to post Share on other sites
legvw 0 Posted December 19, 2011 Report Share Posted December 19, 2011 Never noticed the hole you're talking about when changing engines before? Link to post Share on other sites
MarkGolf 6 Posted December 19, 2011 Author Report Share Posted December 19, 2011 I could well be going mad...I had an engine from a Galaxy or Sharan years back and it had this hole.. Secondary air injection?Either way, to save me rebuilding a spare OBD1 head I've got, I found an obd2 head which I want to buy to save the hassle of rebuilding mine..I bought new guides seals etc etc but everyone wants over £100 just to press the valve guides in and then 2 local firms want £60 and £70 to skim the thing!
