I have a problem tonight I was driving to go out to eat and I accelerated up to around 40 45 you know normal light acceleration and about a half mile down the road i heard a pop and my check engine light started flashing and the car sounded funny so i pull over and sure enough the car sounds like a sti or that im cammed no dipstick came out but i took the oil cap off and there is air coming through there and some smoke I couldnt see the color because it was pitch black out but there was air definatly coming out of the oil cap and it seemed like somewhere around the top of the supercharger. So i left it in the parking lot and Im getting it towed to my house tommarrow so I can take a better look at it. I was just wondering what you guys think it might be. and the past few weeks there has been a ticking noise that does not go away when you rev the engine so I just assumed that it was the injectors. anyway i have a 07 ss/sc with stage 2 and a 2.9 pulley with full exhaust and a dual pass with a C.A. heat exchanger. So if you guys can let me know what you think it might be I would appreciate it and I will update in the afternoon tommarrow with some more info. Thanks for your help.

 

good ol #4

 

can you use the enter key next time? its hard to read that when your are drunk

 

#4 buh bye! sorry to hear that dude. time to plan your build

 

how would i be sure that it is the number 4 piston i hardly drive the car hard and i have all of those cooling mods with only a 2.9 pulley im just lost as how that can happen you know

 

its your tune it seems... your car was running to lean

 

Fuel starvation, your IDC's are maxed on the injectors.

 

who did your tune? what are (were) your Iat2s at WOT? What is (was) your A/F ratio at WOT? do you have an interceptor? did you get any knock? all important questions

 

I thought that a 2.9 was safe on a stage 2 tune you guys really think it is the piston. maybe it could be the headgasket or intake manifold gasket or are you guys almost 99% sure its #4

 

Sucks.

I've got some Forged Pistons w/ Ceramic Coated Tops that I'll sell you for $500.

 

its stage 2 tune on a 2.9 when i go WOT in 3rd my a/f are around 10.8-11 my Iat2 dont go about 130 and im pretty sure i wasnt getting any knock i was just driving normaly when this happened and i scanned it and the code was a misfire code if that means anything

 

put your stage 2 pulley back on and take it to the dealer

 

If it sounds like a WRX... then yes, You lost a piston.

 

sounds like misfires, and backfires thru exhaust. start with finding out the codes and check the plugs before yanking a head off

 

I think Blown 4-banger has a video of the sound... he recorded his.

 

you think they would cover it because last time i went there for a code to get scaned they were saying that i voided my warrenty because of my heat exchanger my gm exhaust and my cold air intake

 

do a compression test

 

it was a misfire code i know that but i will get the exact code tommarrow because i left the car where it was at and im getting it towed home what should i look for when i pull the plugs

 

bring them a copy of this:

Forged Pistons w/ Ceramic Topping - $500 shipped... just PM me

 

white on the plugs

 

thats good right and oil is bad correct

 

no..white is bad

dont count on that though...i would do a compression test right away...it will give you a hint if something is wrong...

 

mine was misfiring on 1 and 3, i changed the plugs, ran ok till i put 60lb injectors in, havent had it tuned yet, it started and ran for a minute, then ran like ****, now it wont start at all......

 

dudes got same mods as me.....makes me worried

i guess the good things now you have a reason to build the engine.
