Also is a oil change required after?

 

yes a oil change will be required. Do the oil change about 250 miles after the seafoaming.

 

K sorry phone got fucked up, thanks again an i dont pay attention to thos guys^^

 

Im goin to do the leak down be4 an after since thos leak down numbers were from be4 christmas

 

Lol i think my tuner knows how to tune he pretty well only does LNF's haha

 

The only thing that should be put through a motor is gasoline and air.

If you're going to argue with me on that, it's pretty much a lost cause.

 

Oil

 

Not unless it's a two stroke haha.

(Hint: Oil for lubrication only)

 

chevycobalt a couple more questions i thought about 1. would the gas additive be done on a full tank? 2. Is this the rite vacume line to put it into? 3. im guessing do the sea foam on a hot engine also? thanks for your guys help i learned alot here.

 

no tht is a purge line dont use that, u can use sea foam now on for a fuel additive, also the line next to it that has a nipple comin gout the intake in the middle thats the one to use .

 

sorry i ment how much gas should i have when i put the 1/4 bottle of sea foam in the gas? also ill be doin this pretty soon i have about a 2000kms till my next oil change. i think i found it.



thanks again for all your help

 

wut i do is have a 1/8 tank then fill it up, and the hose is the correct one

 

k thxs ill keep u updated

 

subd for results

 

K i thought about this i am goin to do the sea foam and after a tank of gas go to the dealer for a oil change and c what they have to say about the leak down test and y there not fixing it since its not in spec an have them do another leakage testan c what they come back wit and if not im goin to write a letter to GM an c y they wont fix it if it not in spec since spec is 25%. There should be no questions its a brand new car. this should be in the next couple weeks.

 

hey bro i know you have friends that work at the deasler but a engine is like a big big big reciept so a warranty cordinator from gm has to look at it first so with me saying this you will prob not get a new engine cuz of this:Fully Loaded, HP Tuned, ZZP Upper CP, 3" ZZP Catless, Drop in K&N, 235/40/18 Nitto 555, Dejon Spring, ZZP 6K HIDs, Murder'd Tails, 17% Tint, Shorty Antenna, Hidden

if so u r one lucky ****...

 

Will c they do shiit of my parenfs an bros car without warranty ex. tranny,new exhaust..but anyways will c but my bros car is fully bolted an gm wanted to the car so the dealer called my bro up sayin pick this car up...so they r pretty good . so will c when i need my oil change what they have to say since this dealer is about a hour an 10 minutes round trip...i just dont wanna blow it an go threw the hassle unless it blows on its own..i just did research on this test an its bad results for a 2010. Anyways its worth a try since if had problems since dayy one since i waited a year if not more for the car...but i would like to have a talk wit GM c what they say..also it only takes a couple hours to go back stock...ill keep u guys updated..also i asked them how often gm comes an looks at cacars an they said they only came once an that was 15 years ago

 

lol 1nce in 15 years damn lol. well the leak down test was completly bad. So they should have replaced the engine already.........

 

yeah well what they do is i only go there and get my stuff done about 2 times a year when i need my oil change adn fix other stuff, and send the paper work out in the mail....and like i stated be4 i have know nothin about motors till i did some research on the tests which is a total fail....and if they say it ohh just wail till she pops which that will be fine but, ill wrtie gm a letter and c what they say and if they wanna look at the car it will be stock..this should should be done in the next couple weeks when a oil change is due...lol btw this is the dealer i go to's junk yard so there into something fishy lol

OPP seize more than 40 stolen vehicles

 

is there other test i can do to narrow this problem down since i think its the rings?

 

If the leakdown test pinpointed a certain cylinder you have a starting point. If you have a compression tester take a reading cranking the engine over through 4 puffs of that cylinder and get a reading. Add a small amount of oil into the spark plug hole, 1 tablespoon and run the test again. If the compression increases greatly it's likely the rings, little or no change it's valves. If two adjacent cyls are low and the reading of either doesn't come up, could be head gasket. All cyls should be within 70% of the highest and none lower than 100 psi.

Make sure to pull the fuel pump fuse and all 4 coil pack connections before you start so it will not run. The service manual says to pull all 4 plugs to run the test also.

With the leakdown test if the rings are bad you will hear air coming out the oil fill cap, if it's valves it'll be in the intake or exhaust, or in my case around #3 injector when the seal was bad.

 

i did a compression test about august of last year (without putting oil in)and it was good i dint write down the results since it was the same all across but would like to do another one.....when i am tuned i do get misfire on 1&4 the odd time but im on stock tune rite now for winter and i will start a fresh tune in spring. thanks again guys ill keep u posted on anymore news

 

so i did the seafoam today.....smoked white like crazy as i was doin the intake mani....i let it sit a lil less then 5 min...started to drive only smoked for about a minute but i drove it for about 20 min...i drop it off at the dealer monday for a oil change and talk to them about this........one question shouldnt it have smoked for longer then that?!?

 

16K mi and 30% leak?
Are ya using any oil (dip stick)? I have tune and ZERO oil consumption @ oil change after 6k mi.
Just my take, but you're getting oil blow-by back up through venting hose (into intake).
No biggie, but you shouldn't be seeing appreciable oil (maybe just a *trace*) in the intake tube.

 

it was only a few drops in the turbo inlet...no oil consumption and no oil on the plugs...im startin to think when thtey did the test the valves wernt fully closed
