You are now faced with this

Start by undoing the 6 10mm bolts Holding down the Coil packs, they should now just pull out and now use your 16mm plug socket with extension to remove the plugs

Now clean the Runner gasket area with some Metho or petrol and a razor blade( WARNING: TRY NOT TO DIG THE BLADE INTO THE SURFACE AS IT WILL CUT GROOVES INTO EASILY AS ITS ONLY ALLOY) once that is done Place new Gaskets and reverse all the steps and your done

There's no need for sealant as the gaskets have locating lugs to stop them moving around and once the bolts are in, they wont move.

God bless my Ecotec. I remember trying to change the plugs on my brothers Camry, wasn't that a royal PITA.

Good How to Mate,

I Had no clue with these and doing a service. No wonder i have never seen the plugs cause did not know you had to pull the whole air intake off lol

You make it look too hard mate, just undo the plennum bolts and shove a couple of blocks of wood in between the plennum and manifold. Doesnt matter if you mess up the old gasket, coz it gets replaced anyway. Dont remove the whole thing.

He didn't say it was the quickest way, just a way he's done it without hassle. A full R&R makes you learn a lot more than just prying away what's in the way in the hope you'll have space to actually work in.

And I'm pretty sure he was commenting on the lower intake manifold, not the gasket, the gasket is probably paper based, the lower plenum is alloy!

Does anyone have the part numbers for the inlet manifold gaskets? Are they the same between the 175, 190 and 190 '05 update?

Cheers and thanks SLIVZ for the how-to, pictures always make doing **** in the engine bay alot easier :)
