Does anyone know the intake and exhaust valve diameters of the L61 2.2L I4 engine? This engine has 16-valves and is used on 2008 cobalt with DOHC.
I am also looking for the BSFC information of this type of engine. If someone can send me a link to the information I really appreciate it.

Thanks.

 

I wanna say the Valve Diameter is 5.96mm at the stem with i think a head diameter of 30.1mm...but i could be off by a little bit...as far as Calculating BSFC use .4 or .5 and you should be in the ballpark...
