oldeskewltoy Posted January 6, 2016 Author Report Share Posted January 6, 2016 eeeeew.... quite a bit of sludge here..... its a good thing this head, and all the hardware are getting cleaned a fair bit of sludge inside the VVL followers as well..... a fair bit of sludge inside the VVL followers as well..... plugged pretty solidly.... This is the return plunger oil drain for the VVL' date=' with this plugged, the VVL follower can't engage, because it can't push against this slug. [img']http://ost.ebeans.ch/albums/userpics/10005/plugged_oil_passage1.jpg[/img] Slug is quite accurate, on this VVL follower, when the VVL was pushed, I had to apply substantial effort, and when I did a solid crud slug popped out... It wasn't always the return plunger, below is the feed hole to the VVL actuator... not going to get a lot of movement when it is substantially clogged. more to come..... :D Quote Link to comment Share on other sites More sharing options...
oldeskewltoy Posted January 23, 2016 Author Report Share Posted January 23, 2016 porting and chamber blending all finished, with the new Supertech valves, the chamber volume has grown to 41.3-41.4 cc per chamber... now the head goes out and gets re-surfaced .004". This should shrink the chambers back to about 39.5cc after the cut. Quote Link to comment Share on other sites More sharing options...
