Ruh roh...Blown Piston Ring w/ pics (56k=death)

[CobaltSSTuner]

**Updated pics and stuff on pg 3

_____________________
We tore apart the cobalt this weekend. Took the head off, and inspected the pistons. The sleeves are in the best shape I could ask for, for blowing a ring. Doesn't look like there is any major machining needed. Just some basic stuff. I figured I cracked a piston, but this is awesome news for me. Car should be back up and running in the next few weeks.

Here are a few photos





On an even better note, i had a box of parts come to my house on sat







As soon as I get the motor squared away, thats stuff is going on^^

Just curious, does anybody know what kind of injectors these are for? They came with the turbo stuff...



I want to give a special thanks to Alex(TeamRevSupport), Tyler(Stealthy1SS), and Eric (Ebristol).

[juicedimpss]

dont forget to pull some more timing out.

Man you just had that things at Gus's sat night. Good luck on the new build. Was it a turbo before?

[CobaltSSTuner]

nope, its supercharged. I"m doing a custom turbo swap. s20g turbo.

[GTSLOW]

Sweet man. I'll still take ya tho.

[Flicktitty]

Goood stuff Jordan, can't wait too see it out.

that snail's been needing to go on for YEARS now.

[CobaltSSTuner]

Sweet man. I'll still take ya tho

eh idk about that lol....

I'm shooting for around 325hp on 15psi. Once I get the basic tuning squared away with the turbo, I want to see atleast 20psi.

geez man long time no talk. And its been a Year lol.

My guess is turbo will be on before the end of may

No that was me at Gus's. I had just come from his house straight to Gus's. My shit actually runs!

The heavy black coating on top of the pistons apears to
be oil from the PVC system, oil and combustion equal
detonation, lead to broken pistons/rings.

Consider installing an exhaust check valve in the downpipe
while the car is down, plumb your VC to this so all the tiny
droplets of oil go out the tailpipe and not into the combustion
chamber. Ive built systems using generic
exhaust check valves from AIR systems on Ford and
Chevys, so well I've had to tweek them from pulling
raw oil right off the pan :o

Another benefit to a crankase evac to the exhaust is it help
seal the rings even under boost, less gas in the crank area
equals more HP and a better running car.

Here is one I made for something, typical downpipe:

Research the angle online, this one works sweet.

alot of his issues have to do with the person who first tuned the car i wont name any names.."cough street attack zach cough huge doucher cough"

Thats a great idea! I'm going to have to look into doing that.

I have a Hahn S20G on my srt4 now...wanna run 20Gs at GLD when yours is done? Mine will be tuned by the end of June

[CobaltSSTuner]

hell yea, I'm down. How much boost are you planning on running on ur s20g?

[GTSLOW]

No that was me at Gus's. I had just come from his house straight to Gus's. My shit actually runs!

shit there's to many of you in here.

[srt4eh]

I'm looking at 24-26psi....
