ring SEAL
From Old & tireder
I am not in the category with Hink, So lets git that clear from the git go. I build my on CNC equipment and am building a new Cylinder hone so that I can change every variable of the honing process. I have used all 3 types of ring sealing,1:No gas porting,2: vertical porting 3: horizontal porting. Certain rings will seal better in each of the conditions noted. One thing that I have found is that, if the pistons are not good on land flatness, you can get much blow by with vertical or horizontal porting. Both methods are made to push down and out and if it dont seal against those 2 surfaces it heads straight for the 2nd ring. So you better do sumtin right with the 2nd ring. Also I have found that you should hard anodize the ring lands if you are going to vertical port. I made me a cylinder that is as round as I can get it to play with rings in cylinders. In doing so I found more problems with pistons than I did with rings. All this time I thought rings was always the culprit : not so. We can talk more if you like. I hope Hink jumps in so I can learn more
I think I should have left my 3 degrees at work when I retired and sold my dyno so I could spend more time at home or so the boss says. HeHe
