dragbanshee Posted July 23, 2008 Report Posted July 23, 2008 Well I finally decided to install my noss head after having it for a month, anyways I pulled the stocker off and found a lot of pitting on the right side. The left side didn't look to bad, I think this may of happened on the last rebuild cause the pistons look excellent I think. What would cause this to happen? It always ran fairly cool, never overheated with me and was rich if anything, thats why I think it happened to the previous owner over a year ago. I have pics below if you could take a look and tell me what causes this. One other thing I wrote some #s down and got shots of them to see if someone could tell me the size maybe....#s on piston H64I8 / 100mm /513p4 /cd this exactly how they are on piston. Thanks! Quote
Wildcardracing Posted July 23, 2008 Report Posted July 23, 2008 Looks like the previous owner burned it down. Those pits are from chunks of piston/ring smashed into the head, Your current pistons look just fine. Off the top of my head those are wiseco numbers for a .040 over prolite piston (65mm bore). Hope that helps. Quote
