oldeskewltoy Posted January 6, 2016 Author Report 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
oldeskewltoy Posted January 23, 2016 Author Report 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
