REmove #1 spark plu
Remove Valve cover
Manually turn engine over (use a socket on the crankshaft)
until #1 piston is at the top of the cylinder and #1 intake valve is opening
This is Top Dead center
Remove distributor and replace so that tail of rotor is pointing to No. 1 wire
Number 1 cylinder, which would be the first cylinder on the drivers side of the engine. You want the rotor pointing towards the 5 O'Clock position looking at the distributor from the front.
should be in a straight line from center of the distributer cap to the #1 cylinder, or pointing at the #1 cylinder
When the #1 piston is at TDC./ TOP DEAD CENTER on the compression stroke the rotor should be pointing towards the #1 cylinder when the distributor is installed correctly.
hello there, first you have to have the rotor button pointing to the #1 cyl at top dead center. if you do not know where top dead center is then take the spark plug out of the #1 cylinder which by the way is the front spark plug on the drivers side. which is the plug closest to the radiator.then have someone bump the engine over quickly while your finger is over the plug hole this may take a few times and when you feel the compressed air blowing your finger off then the piston is coming up to top dead center "tdc" now your rotor button should be pointing at the #1 cylinder.when the rotor button is pointing at the #1 cylinder this means it will be pointing towards the #1 spark plug hole. the cylinders on the drivers side are #s 1-3-5-7 and the cylinders on the passenger side are #s 2-4-6-8 when you put the distributor cap on there is usually a #1 where your #1 cylinder plug wire goes which by the way the rotor button will be pointing at that plug wire connection on dist. cap then in clock wise rotation on the distributor cap they go on as follows 1-8-4-3-6-5-7-2 if the rotor button is pointing at the fire wall towards the passenger side the your distributor is 180% out of line and of course the oil pump shaft will not let the distributopr fall into place properly if they are not lined up. you may have to turn the oil pump shaft in the correct direction so your distributor will drop into place when pointing towards #1 cylinder. you should be able to do this with a long screw driver.
1st cylinder on passenger side towards front of vehicle..fire order 18436572
low coolant
Under the car towards the rear axel.
You need to find TDC then remove cap and see where rotor button is pointing.
be it a 4,6,or8 cylinder....be sure you have the crank on TDC, top dead center, install the distributor so that the rotor is pointing to #1 cylinder on the cap
18436572 The #1 cylinder piston must be up on the compression stroke when the rotor button is pointing to #1 plug wire on the distributer cap. The firing order is counter clockwise around the cap.
firing order for any Chevy v-8I am a Chevy owner and racer, the firing order on any Chevy v-8 is as follows: with the distributor rotor pointing to #1 cylinder, and the cap is on, the order is: 1,8,4,3,6,5,7,2
if its a v-8 it is 18436572 number one on the cap should be pointing at number 1 cylinder is there a picture of the cap
