is it the issue of a cylinder going down? if so why? because my car now sounds like it but the power is still the same. from idle to a snappy rev it sounds like it has a miss but has full power? its been one thing after another with this car

 

Ya the subie sound is no good! I would go rent a compression tester from autozone. If the numbers are all the same then your fine, but there is a problem somewhere. If your numbers are like 60 60 45 60, then your 45 cylinder needs new piston rings.

 

Its in the valvetrain pop the valvecover off and look for a broken rocker. Whatever it is will be obvious

 

^x2 might see some lash adjusters lying around in there

 

It will most likely be the opposite,

you might find rocker laying around and at worst broken lash adjusters.

 

Just think positive, once this is fixed chances are you're good for awhile!

 

Take off the valve cover

 

i do not doubt this one bit....my buddy drove it last night and jammed 2nd from 3rd.....(smacks face) its the last time someone else will drive my car and actually was the first other then my mom

 

if they're down below 100. you'll need all new rings hahaha.


OP if you're not getting any smoke and the car runs fine. check your oil, make sure its not milky or contaminated with coolant. and take off the valvecover. when you say your friend "jammed 2nd from 3rd", he over revved it. and theres atleast one rocker arm that's fallen off.

if you didn't bust a lifter, you can put it back in with a hefty flat head screw driver and a good amount of force, but you'll need another set of hands as well.

it'll look like this



if you did bust a lifter, you'll need to make sure you get out every last little piece of metal you can see. get one of those magnetic pick up tools and get in every little place. then drain and change the oil and filter. replacing the lifter is easy. if the cam lobe is in the way you can crank it and turn the cam and then with that magnetic pick up or needle nose pliers just pull the lifter out. i thiiiiiink you can order them individually from gm, by zzp sells them in sets of 16.

it'll look like this

 

you're rockers will look a little different though

 

Or instead of going crazy assuming the worse (which of course is still always a possability), you can test your bank1 sensor 1 o2 and make sure it's still in good shape. A bad wideband will cause random misfire and maf skew which as a result can cause the dreaded scooby sound. While your under there check your plugs as well just for cheap insurance.

It's pretty common to eat through o2 sensors when tuned on the stock turbo due to high egt's.

 

man thanks for the walkthrough for real! that should be stickied as ofter as people have this problem.....He says he is gonna pay the bill so im just going to get an appointment at the garage monday but if he backs out or something stupid like that then ill be taking this step by step

 

Money shift = broken lash adjusters. Sorry, man. You just got that thing running right!

 

I got the subie mod after my lnf didn't like and ate a 1 step colder ngk spark plug

 

I know man it's a tough lesson. I mean this dude has neve owned an automatic in his life I thought hey surely I can trust him but no we almost go through the windshield due to epic fail. You shouldA seen my face it screamed man ur gonna pay to have this **** fixed

 

Do any of you guys know of a video on putting the rocker arms back with a screw driver? Cuz I'm prObably gonna do this job myself

 

What i did is just loosen all the bolts for the caps that hold the cams in place, dont remove them , just loosen them equaly until you can put the rocker back in (you will still need to use something to help putting them in place... you will figure out what i mean). Then retight the bolt to the spec. I dont remember exactly, something like 87lbs.. im sure someone will give you the exact number.

If you have broken lash adjusters, you will see them

Heres a pic where the rocker is missing, but the lash adjuster is still there(the bolts im talking about, those you need to loosen, you can see one in top right of this pic):



I still have a few brand new lash adjusters if you need any just PM me.
To remove the valve cover you will need to remove the braided line that go from the valve cover to the turbo, remove it from the turbo, its one bolt, then you can use your finger tip inside of the turbo intlet to help you getting the braided line out... its pretty snug in there.

Other than that its just removing all the parts in the way.

 

I did the Subie mod to my SS and couldn't be happier!


Wait....we aren't talking about the same thing, are we?

 

If these cars sound like a wrx when blown, What does a blown up wrx sound like?

 

lmao i was just bout to make a philosoraptor to that effect

 

^Like a seriously ragged out diesel.

 

have the same thing going on... mines currently in the shop right now. hopefully they'll find something out...

 

wait, would this call fluctuating vacuum? and how long would ur car be able to run if something like this happened?

 

A Cobalt SS

 

you don't need to loosen anything holding the cram down. just turn the key as if to turn the car over and it'll rotate the cam. have someone tell you to stop it when the longer part of the lobe is up.

then with a big flat head screw driver, push down on the spring and have someone else push the rocker arm in. it takes some force, but its doable in a few trys.
