Re: My distributor was out of vehicle and my buddy turned...
Hi there... The first thing you want to do is position the # 1 cylinder a top dead center of the compression stroke. You can do this by pulling the #1 plug and manualy truning the engine till you feel air being pushed out of the plug hole. Continue turning the engine till there is no more air being pushed out. don't go to far cause then you'll be on the intake stroke and you'll have to turn the engine the opposite way. After that is done, find out where the rotor position is for #1 on the distributor. (you can do this by looking at the cap and matching it up with the #1 plug wire. Mark the edge of the distributor where the position is and install the distributor. you'll have to move the shaft one way or another.ie clockwise or counter clockwise to get it to align when the gears match up. Once the distributor is installed you can complete everything and set your timing.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

If you got the distributor in at least close to where it originally was, leave it in for now. You will have to find TDC for #1 cylinder by turning crankshaft until you see and line up timing marks. When you line up the timing marks, you will be on for #1 or 180 degrees off. You will able to tell by pulling the cap and seeing if it's pointing at #1(or near it). When you're sure you are lined up TDC on #1, pull the distributor, noting how much the rotor turns counterclockwise(CCW) when pulling dist out. Now hold the dist housing in the position you want it to sit in the block( determined by where #1 spark terminal will be), the rotor should be CCW about 1 1/2" from the #1 term, then lower dist housing down while watching the rotor turn clockwise and line up with the #1 spark plug terminal. The dist housing will be flush with block if done correctly. It takes some practice, but as long as you get #1 lined up at the crank timing tab and don't disturb it, you can play with the dist all day. The trick is, you have to get the oil pump shaft lined up with the drive tang on the bottom of the dist. You can use a long flat blade screwdriver to turn the oil pump shaft to the right clock position so it lines up when you drop in the dist. Remember to hold dist housing steady when lowering and let rotor turn into position. Good luck.
Follow this easy instruccions if you want to reinstall a distributor on a vehicle where the crankshaft was moved from the position it was when the distributor was removed.
Remove #1 spark plug
Place your finger over the spark plug hole while turning the engine with a wrench on the pulley bolt at the front of the engine.
When you feel compression continue turning the crankshaft slowly until the timing mark on the vibration damper is aligned with the "0" on the engine timing indicator.
Position the disttributor rotor between the number 1 & 8 (for 8 Cil.) 1 & 6 (for 6 Cil.) or 1 & 4 (for 4 Cil.) spark plug terminals on the cap.
Lower Dist. into engine. To set the gear on the bottom of the distribuitor, you may need to turn the rotor a little bit. If the distributor does not drop down flush against the block is because the distributor shaft has not mated the oil pump shaft, if this happens, place a large socket w/braker bar on the crankshaft bolt and turn the engine over in the normal direction of rotation until the two shafts engage properly and the distributor sits flush against block.
With the base of the distributor properly seated, turn dist. housing to align the marks you made in dist. base and engine block. (you did make this marks before removal right? : )
Place the hold down clamp and install the hold down bolt not too tight. Install dist. cap an reconect electrical plugs, spark plug wires, etc.
Check ignition timing and when set, tighten dist. hold down bolt.
If you have to pull the distributor, take off the cap and mark on the dist. housing the position of the rotor, exactly where it is pointing to. Also mark the dist. housing relative to the engine block, or the adjusting bolt or nut, so when returned to its place in the block, the distributor is in the same exact position. Do not rotate the crankshaft with the distributor out, or you will have to re-time it.
To re-time the engine, you have to put the #1 cylinder at Top Dead Center of the compression stroke, then drop in the distributor with the rotor pointing to the #1 cylinder plug wire tower. Now it is in time at zero degrees. Get it running and warmed up, then use a timing light to set it at the BTDC specification.
To find the compression stroke of #1, pull the #1 spark plug and turn the engine clockwise with a socket on the crank pulley bolt. Hold your finger over the plug hole. When you feel pressure build up, you are on the compression stroke (there is an exhaust stroke and a compression stroke-when the piston is rising on the compression stroke, you will feel the pressure. There is no pressure build-up on the exhaust stroke.) As soon as you feel the pressure, look at the crank pulley and continue turning the engine clockwise until the notch or mark on the pulley is lined up with the zero degrees mark on the pointer scale. The #1 piston is now at top dead center. Now drop in the dist. with the rotor pointing to #1 spark plug tower. However if the engine was not disturbed while the dist. was out, you don't have to retime it if you marked both the rotor position, and the dist. housing relative to the block where it sits.
With ignition OFF, remove the dist cap , do not remove HT leads from cap or plugs just move to one side ,turn the crankshaft with a spanner on the crank pulley drive nut until the rotor arm is pointing directly towards the front of the vehicle, mark the position of the rotor on the distributor body with a dab of paint and also mark the position of the body on the engine block infront of the distrbutor,remove the distributor , i believe it's just 2 screws that clamp it in place ,transfer the mark from old dist to the new dist and aling the rotor to this mark, then fit the new dist to engine and aligne the marks from the new dist to the mark on the engine block and tighten down , refit the dist cap , to get an exact distributor timing you should now use a timing light to check the timing marks line up , if they are slightly out just very slowly turn the distributer until the marks are aligned , hope this is of help
You have to retime it. You put number one cylinder at top dead center (TDC) of compression stroke, then drop in the distributor so the rotor is pointing to number one tower on the distributor cap. To find TDC of compression stroke, remove number one spark plug. Use a socket and ratchet on the crank pulley and turn clockwise. Keep a finger over the number one spark plug hole. When turning the crankshaft and you feel pressure against your finger, the number one piston is rising on the compression stroke. Now use the ratchet and turn the crankshaft on around until the crank pulley notch lines up with the zero mark on the pointer scale. Piston will now be at TDC. You can now drop in the distributor. When seated, the rotor must be pointing to the number one cylinder on the dist. cap tower. Dist. shaft will turn as it is seating-if you get it wrong, pull up distributor and reposition the shaft until it drops down into the exact right position. When done, start the engine and use timing light to set the timing to specs.
Disconnect the battery. take cap off but leave wires intact. Check position of rotor for reinstalling. Loosten bolt under distributor and take out. Lift didtributor and turn rotor counterclockwise to remove dist. Make sure you put back in same identical spot.or vehicle will not run. Mark spot on motor where rotor is if you can't remember. You have to turn rotor counterclockwise to have dist. fall back into same spot. Will be tough to get out at first. Don't spray with penetrating oil. Just pull up and turn.
okay, did you have these items out of motor or did it quit running and this is what you have checked? I can fix this problem but i dont know where to start with this information. I can say that the crank has to be at zero,the #1 piston needs to be at TDC( up in cylinder) the cam sprocket has a mark that should align up with crank, the dist rotor should aim to #1 cylinder and the dist cap position wire should go to the #1 spark plug, If this was all in tack and now the truck wont start and this is your diagnosis then i would check the timing chain and gear for worn or nylon broken timing gear . If you put this together and you noticed this then you can either remove dist and align oil pump shaft and re-install or move the plug wires one post starting with the rotor aim as the #1 wire and proceed in a clockwise rotation 1-8-4-3-6-5-7-2 . As long as the dist can move for timing purposes it doesnt mater where the #1 wire starts as long as the #1 wire starts where the rotor aims and the motor is in time. If everything was in tack then the chain has jumped and needs replaced.
