i just want to know how many bolt i need to loosen before i can take it off? i removed 5 bolts and 2 nuts already but still i cant take it off. i was wondering maybe the manifold stuck to the engine.

bump i really need help

bump desperATE

 

They were all across the top right? None are underneath and you can see them all from the top, if you have them all off try tapping on it GENTLY or wiggleing it. Also those 2 studs, take them out it makes removale and instalation ALOT easier! I know its a amle torx but if I remember correctly a 5.5 mm socket works great.

Hope this helps you, good luck!

 

There are only 7 Bolts Holding it on! It Might be Stuck alil, Wiggle it back & forth alil to break it Loose! Did you buy the New updated Intake Gasket?

 

yes sir i did buy the new gasket cuz i had a popped dipstick. when i looked into the supercharger it sucked in some oil but the rotors are not covered with it . i think it went through the pcv idk. thank you very much for the info. i might get me a rubber mallet and tap it. thaks alot

 

Down on the bottom, behind the alternator, is a 15mm bolt! You will need to feel for it or use a mirror to see it.

 

looks like you have the dual pass. how do you take that bolt out?

bump

 

If I remember right, I removed the alternator bolts and pushed the alt. aside to gain access to the 15mm bolt.

 

wow thats alot of work there. i thought its gonna be easy. they should have put that on the lsj build book. they only mentioned the top part. thanks

 

No problem, I did get your PM, I hope this answered your question.

 

After you remove the bolts and studs from the top of the manifold, you should be able to snake a ratchet under there with a universal to access that last nut. Don't take it all the way off just loosen it. Then you can rotate the manifold toward the front of the car and replace the gasket.

 

Dude there is 2 bolts underneath .You have to take the intercooler pump and bracket off so you can get to them. They have 13 mm heads on them. I also had to pull the oil dip stick out to get the intake off.

 

how about the 15mm bolt that they are talking about. im confused some say one more 15 mm some say 2 more undertneath. are all 2.0 made the same?

i tried to look underneath with a mirror and i dont see the two bolts just the 15mm bolt. pls help.

 

so has it been confirmed that the intake gasket is causing the intake gasket to pop out? is there a TSB on this?

 

here is a pic the head size is definatly 13 mm you and see the braket on the bottom this is where the he pump bolts so you have to take that bracket off. don't take the studs out of the head they don't need to come out and they hold the gasket in place.


What does this mean??

there is a bulliten on an updated gasket but it would be a warrany concern.I took mine off off to do the dual pass mod and am putting in the updated gasket.
here is how I set up my cores.I will be feeding in the centre and returning from the top and bottom.



Models: 2005-2006 Chevrolet Cobalt SS

2004-2006 Saturn Ion Redline

with 2.0L Engine (VIN P - RPO LSJ)






Condition/Concern:
On rare occasions, the engine oil dipstick may become unseated on hard acceleration, resulting in an engine oil leak. If the engine is operated long enough like this, a P0171 DTC could set due to the engine ingesting unmetered air.

This concern is the result of excessive crankcase pressure on hard acceleration. This crankcase pressure may be the result of an intake manifold gasket concern that allows supercharger boost pressure to bypass the intake manifold gasket where it seals around the PCV orifice, which is between the #2 and #3 intake runners.

Recommendation/Instructions:
If the SI diagnostics do not isolate a cause for this concern, replace the intake manifold gasket using part number 12597855, which contains an updated sealing surface around the PCV orifice. This part number, or any future part number, is designed to address this concern.

i'm sorry i ment has it been confirmed that it is the intake gasket that is causing the dipstick to pop out? is there are TSB?

Good **** dude! looks like i'm making an appointment at the stealership!

 

looks like im lucky cuz i got the 15mm bolt and intake manifold is loose. im lucky to not have those two bolts and take the pump off. Thanks to everybody specially Njblues

thaks Spaz but i think i got the 15mm bolt and now its loose. I think the 15mm bolt goes to that bracket. thanks for all the help

 

Yeah the 15MM attatches the manifold to the lower bracket.

The pump bracket is easy to remove if you first remove the pump and the outer cup the holds it. That frees up enough room to move around.

I wish that GM would acknowledge that lower bracket is there. They don't even show it on any of the build books or the Stage 3 dual pass install.
