Thread: Trouble shooting/ rebuilt

  1. #1


    Default Trouble shooting/ rebuilt

    Hi,

    I purchased a 2002 viper sx with the middle piston damaged. A new project for me that I have no experience with yet! I read many threads here and I agree that if I am to rebuild it I should find what caused the failure. By looking at the pictures, any input as to what may be the cause...? I know that the cylinder and piston are no longer good, but the head? if you look close at the picture I circled in red a tiny area where a small hole as formed, does that make the head destroyed or it can be saved?

    Sorry, I dont know why but come pic upload and others not......

    hope those can be of assitance

    Thank youCYLINDER.jpgHEAD SPARK PLUG.jpgPISTON 2.jpg

    Dirty carbs or bad fuel caused detonation. Head should clean up fine.

    Great, thank you.

    but i'll try to post a proper picture of the head tonight so you can see the tiny hole I am talking about. The size of the picture might just be to big.....

    Those vipers run hot, raise the clips on the needles up one notch, add a rear heat exchanger and add the opticool headgasket.

    HEAD HOLE 1.jpg

    Great thank for all the advice! Truly appreciated. I was finally able to upload a picture (not the greatest...) but if you look at 10 o'clock on the edge of the dome and where the gasket seat, a tiny hole, 1/16 in diameter and approximately the same in depth. Should I be concerned by that? not? or have it filled somehow by welding....

    thank you

    buff it so that the tiny hole disappear or just make the edges of the hole smooth?

    I purchased today a used cylinder and piston. I was so confused with all the forums search on aftermarket piston spi/wiseco.....OEM$$$. That I decided to go with used, still in good condition OEM piston and cylinder.
