If you have not heard already I had an engine failure in my 03 on Tuesday. It appears to have been a ring failure in 7. It really was not unexpected and I am currently planning on really setting it up right now.

Do you think it is a random failure or is it a result of tracking, mods, or something else?

Toofast,
That sucks...
More Cooling mods are on the way....Evans came up with this flange. We need more coolant flow from the radiator...PM Sent

toofast4u said:The problem as I understand it is primarily due to the piston design to meet customer expectations and EPA standards. The rings are two close to the top of the piston. Also the forging is using a weak material that is actually two big for the cylender. This is to prevent the clanking that aftermarket forged pistons make when cold which would have some customers going nuts. The engine builder I am using said everything else in the 03 motor is very good stuff and doesn't really need to be changed.
ShelbyGuy said:doing the apten cooling mod while you have it apart, or did you have that done already?
the rear of the drivers side cylinder head apparently has an area that develops pockets of coolant that dont flow.
