A few years ago I built a 6 bolt with Wiseco 10:1 HD pistons. I was setting the block up for 30+ psi, and to be mainly street driven. I requested a .004" PTW clearance from the machine shop.
I set the rings at
TOP: .020"
Second: .024"
The pistons ended up failing due to a MFG issue and Wiseco stood behind them and send me a new set. BUT I had to re-hone the block. When I got the block back from the machine shop it measured 3.3683" putting my PTW to 0.0045. From what I have read this is not issue at all.
I order Wiseco 85.5xx rings, the top has plenty of meat to file/fit, the second has a 0.027" gap from the box. I don't really want a gap that big.
I called Wiseco and they send me 86XX rings, and never answer my question on the ring being a different diameter than the cylinder and if this is a problem. I file down one of the second rings just enough to get rid of the overlap and with my flashlight I can see a TINY bit if light between the cylinder wall and the ring ONLY by the gaps.... now what.
I call Total Seal, they are less than no help, I wont be dealing with them again if I can help it.
Now what are my options, I am sure someone else has gotten into this territory.
Thanks for the advice.
