i came accross a post about this before but now I cant seem to find it...is there any difference between the valve covers for the 2.2 and 2.4...are they exact fit? any gains if go 2.4? If i remember correctly on the 2.4 there are 2 holes on the side for some kind of hookup that the 2.2 doesnt have..is this true?

 

You won't get any preformance gains from swapping valve covers. Yes they should be a direct fit. As as far as the 2 holes....not sure about that but they may just be for vaccum lines.

 

umm so which is it? lol

 

2.4


2.2

 

Looking at those pics, I'd say it's not a direct fit. The mounting points at the cam sprockets are definatly different. The 2.4 even has one in the center.

Is the one for the 2.2 the non VVT varieth?

 

does the 2.2 have any writing on it ? i like how it says ecotec vvt

 

I believe the 2006 2.2 did not have vvt . Seems like it was in 07 that it went to the vvt where as the 2.4 was always had vvt. I know it read it someplace on the forum.

 

The 2.2 added vvt in 2009+, with flexfuel capability.
