Will this improved #12597855 Ecotec Intake Gasket be similar to the newer LNF intake gaskets?? Or a Saab 9-3 turbo gasket? (Same head)

LSJ parts are not supported here in Europe, but Saab or LNF 2.0 Ecotec parts I can just order at the dealer around the corner...

Is there a TSB for this or can I go to the dealer and say replace this for me please?

guys, does anyone here know how to remove the oil dib stick along with the bracket, without having to bend anything? see, mines broke on the braket where it bolts to the intake manifold, therefore is lose and ive been having issues with oil coming out from the end of the tube, when car is in motion. i try looking for some info in how to take those out but didnt have much luck. any help would be really apreciated.

thanks!

mine looked identical besides the print is much larger but it helped and no dipstick shooting out anymore so woohoo its fixed!!

You probably put them on top of each other and checked the holes to see if they lined up. If it was the design of the gasket, it would be a height issue where boost could bypass. You wouldn't notice it if only checking the hole size.

Just my 0.02

just fixing my 2007 cobalt from this problem it was a cracked piston. Thought it was just the rings till i opened it up. I was running about 19 to 20psi of boost so im fixing it and turning down the boost.

im havin an issue with the dipstick popping out an inch car runs great i had a new head gasket put on recently and i have maybe 2months on my phenolic intake manifold spacer with new gasket..what next?

Tjolley

pistons

jred89

but if it was the pistons wouldnt the car be runnin like ****?

Tjolley

nope my car ran fine..
u might see if the pcv valve went bad in the intake mani

Do this
Start your engine and pull the vent hose that goes to your intake from the back of the valve cover off the air intake.. Put your finger over the port on the air intake to keep the engine from running bad..if u have a ton of air coming out that hose i would bet money its a cracked piston

jred89

ill try it

jred89

Ok I tried it it was a normal flow of air not alit of pressure..

Tjolley

hmm...i don't have hardly any..that's how i built my engine...
well next u need to do a compression test and. cylinder leak Down test.

jred89

jred89

I'm lookin at aftermarket it's the next thing on my mod list I'm already putting 300whp fully bolted with 160,000 miles so of I replace the rods pistons with aftermarket it will be stronger and like new cuz everything else is replaced

jred89

murderedoutcobalt

hey guys I'm new to this site I. have a 2006 2.0 supercharged ss I'm having a random misfire I took it to 3 mechanics n can't figure out why it's misfiring I replaced spark plugs coil packs n still misfiring I brought it to a thrid mechanic n he said it could be the intake gasket like everyone else is talking bout do he replaced it n still throwing random misfire code any suggestions on what it could be I live in central nj n was wondering if there's a shop that works on cobalts that can scan my computer to see what kind of tune I have on it
