All cylinders are numbered from 1 in the front to whatever in the back.
There are variances on V8 and V6 motors where the numbers are either odd or
even on one side, or sequential, but 1 is always the forward most cylinder
on the crankshaft and the highest number is the rear most cylinder on the
I got into a lengthy discussion a few months back about whether #1 was on
the right or left bank, but I could have looked for myself and found that my
argument was flawed. I promoted the notion that #1 was the left side first
piston, but on my own vehicle, it was clear that the right side bank of
pistons was forward with respect to the right, making my argument to be in
Despite my confusion on which side was forward of the other, the #1 piston
is always the forward piston on the crankshaft. The rest are numbered toward
Keep in mind that front and rear of the engine are relative. If the motor is
sideways, the front could be on the left or the right side, depending on the
engineers. I seem to recall that my Hondas had the front of the motor to the
left side, but I can't say that the front will always be on the left. It
should be a safe statement that the rear of the engine is the end that has
the transmission bolted to it, and the front is the end that has the belt(s)
that run the auxiliary stuff such as power steering and air conditioning.

And to make matters worse, for the longest time Honda engines ran
backwards. I think the engine in the S2000 was the first one that ran
the 'correct' way. It may have had something to do with Honda's
ambition to be an engine supplier to other car makers. GM uses Honda
engines in some marque models now, though they don't advertise it. I
think they should, I'd buy a _shed_ with a Honda engine in it -
knowing that the engine will therefore be the *least* of my problems.
