Why Broken Pistons Why?

[matrixym]

i put turbo on my da. after about 3 months the engine was burning oil and smoke was comming from the valve cover. i opened it and found the pistons broken between the first and second piston ring. i put new pistons and piston rings and after alot of work i had it all fixed. i started driving and at 72 miles the valve cover was smoking again i think that the pistons are broken again. do you guys know why. or if this has happened to you please let me know what it was. thank you.

Broken? Do you have pictures?

I have heard of pistons melting and getting holes in them from running lean, but never the channels with the rings breaking.

Did you have the car tuned after installing the turbo?

did you just put a turbo on it?

no tune, no engine management, no fuel system?

 

[Cheesenip]

bet it ran lean

no way it you cracked a piston

pictures or it didnt happen lol

i need a picture of the piston and i can tell you what it is that is causing the problem

You've never seen a broken piston? You act as if it is impossible.

I'm willing to bet detonation cracked the ring land

i do have pics and i have the aem airfuel gauge, safc ii, oil pressure guage, boost gauge, volts gauge, and i know it was not running lean. besides i never went over 6000 rpm and they broke after 70 something miles.

You may have all of that, but did you bring it to a shop to have it properly tuned? Do you have an upgraded fuel system, as in larger injectors/fuel pump?

I DONT KNOW HOW TO PUT PICS BUT LETS SEE IF THIS WORKS.

I hear a list of gauges, but not a damn thing that resembles a fuel system or decent engine management(SAFCII blows).
I agree with Kyle.I bet you had detonation out the ass.

LET ME TRY THIS OTHER PICTURE

 

[BrokenTalon27]

What is you're fuel set up, injector size, etc.? How much boost and on what turbo?

this is another picture i have so you can see it all 4 were broken now with my new problem i dont know how many of the pistons broke.
