Hey. looking into grabbing an l61 for my brothers build, question is how can we tell an 05-06 vs and 07 L61 apart, when they are not in the car, is there a serial number stamped on the engine that provides this info! Thanks!

 

The valve covers of the 05-06 have lines indented into them and the dont have individual coil packs.

The 07 has a smooth top valve cover that says ecotec on top and has individual coils

Im sure theres other ways to tell too.

 

didnt know this, but im going along with it


this is how my valve cover looks on my 05 l61
