If i'm standing in front of the car and looking at the engine. From left (passenger side) to right (driver side) -- what is the piston numbers?

I'm planning to follow this directions. Just need to know which is piston 1, 2, 3, 4.

UPDATE: From Passenger to Driver the cyclynders are 1, 2, 3, 4. Firing order is 1, 3, 4 2 - meaning as you turn the crank clockwise you'll see those numbers on them.

I'm sure somebody else will chime in, but typically numbering starts from the front, which is the end with the pulleys (opposite to the transmission). On most FWD cars, that is on the passenger side of the car, so as you stand in front of the car looking down at the engine, #1 is on your left. Firing order on most 4cyl engines is 1, 3, 4, 2

 

awesome thanks!

 

Most Hondas are 1-3-4-2. I have never checked a FIT. If you are adjusting valves you should be able to verify this by watching the valves.

 

I'm assuming i'm watching what piston turns up top next?

 

it's a flat plane crank, two pistons will be TDC every 180*.. you need to watch the valve sequence. For example, pull the spark plugs and spin the crank over a full 720* and watch the valvetrain for cyl #1 (there are marks on the cam gear that reflect TDC for each cylinder as well)

 

I working on it as i'm posting this.

I did as instructed.

-Turn clockwise to "UP" and adjust intake & exhaust "1" .
-Clockwise again to "3" and adjust intake & exhuast "3".
-Clockwise again to "4" and adjust intake & exhuast "4", BUT the issue is exhaust 4, I loosed the nut and screw but the valves as stuck tight, will not loosen.

Currently this is where i'm stuck.

Am I doing something wrong, I'm suppose to match the crank # with piston number?

I just took this picture.

 

looks like I had the cylinders wrong.

 

Holy shit lol

 

You got it figured out now, mxl180; they're numbered in order 1,2,3,4.

The 1-3-4-2 is the firing order. Cylinder 1 fires first, followed by 3 (after half a crankshaft rotation), etc. They fire in that order (and not in sequence down the line) to lessen/even out the engine vibration.

 

thanks. completed. idle is same but I'm noticing revs 3+ sounds smoother.

 

mines is loud lol : / i was think of haveing dealer look at it but its not that bad i guess its w.e still pushes hard even with my heavy tires lol : /

 

I looks like you got it figured out. On a 4 cylinder, one cylinder fires every 180 degrees of crankshaft rotation.

There are 4 strokes each 180 degrees of crankshaft movement (and 90 degrees of cam movement):

1. Intake - Intake valve open - Piston moves top to bottom
2. Compression - No valves open - Piston moves bottom to top
3. Fire (or power) - No valves open - Piston moves top to bottom
4. Exhaust - Exhaust valve open - Piston moves bottom to top.

When adjusting the valve clearances you want to be at the point between stroke 2 and stroke 3 (Top Dead Center on the given piston).

Clear as mud. Right?
