MarcD Posted January 15, 2006 Report Share Posted January 15, 2006 I just got a new reco 4K-C into my wagon and whilst Dad and I were putting the manifold on, we noticed there are 4 holes at a 45 degree angle on the side of the head on the side where the inlet/exhaust manifold goes. We had a look on the old engine and these holes were not there. We blocked them up but neither Dad or myself knew what exactly they are for.

Rolla__Boy Posted January 15, 2006 Report Share Posted January 15, 2006 They are for emissions. My 5K had them too, I just blocked them off. Quote Link to comment Share on other sites More sharing options...
