Does anyone know how the cylinders are numbered for the DI engine looking at the engine from the front of the car? I feel stupid asking this but there is conflicting information on the web. I know the firing order is 1-2-3-4-5-6 but where is #1 cylinder and how are they laid out? My Chevelle's engine has the #1 on the driver's side front with odds on the driver side and evens on the passenger side from the front so I am showing my age. Thanks for the understanding. :hide:

1-3-5 pass side, 2-4-6 driver from front IIRC

No. Even cylinders are on the driver's side and odd are on passenger side.

I know the firing order is 1-2-3-4-5-6

Having trouble imagining that this is even possible. (?)

Yes, as loosend said, the firing order is 1-2-3-4-5-6: http://www.gmpowertrain.ca/Product/3.6 VVT DI/LLT Specs.pdf

To be absolutely certain, the firing order is always cast into the intake manifold.

Yes, I saw that this morning, was under the apparently mistaken assumption that firing "in order" was only possible with a radial layout.
Would certainly like to see a photo of this crankshaft.
Thanks for the info

I thought the same thing about the crankshaft and yes, I verified they swapped the odd cylinders to the passenger side and evens to the driver side as I had coils on cylinders #4 and #5 replaced at the dealer and just checked their positions. Thanks for the replies and this thread should help people who get cylinder codes in the future.

Do you mean like a rotary engine that Mazda was known for?

No, I was referring to a radial (aircraft) engine where the cylinders are like spokes in wheel. The term rotary in aircraft refers to the same cylinder arrangement with the crankcase and cylinders rotating around a FIXED crankshaft. This fell out of favor after WW1 Same goofy set up was used ( briefly!)in 3 & 5 cylinder configuration in an obscure rear engine auto called the Adams-Farwell. However I did buy the 1st gen RX-7 when they debuted in `78. Smoooooth, no torque !
