Need to no how the dots lines up on1984 ols 5.0 timing gears

adjust the distributor until thy line up

What car do you have? A repair manual cover this.

Replacing the chain and gears requires removing the water pump, dropping the oil pan, removing the balancer and timing cover. Rotate the crank so the dots on the cam gear and crank gear line up at the 6 and 12 o clock positions respectively. Unbolt the cam gear and remove it and the chain. If you need to remove the crank gear you can use a three jaw puller or something similar to pull it off. Reinstall the crank gear lining up the gear with the keyway on the crank and press it on with the appropriate tool. Install the cam gear with the chain and make sure dots line up again. It may be necessary to remove the valve covers and rocker arms as well to rotate the cam shaft if need be.

My geuss would be the timeing chain is not correctly alined . Alot of chevey engines need to have #4 cylinder at top dead center to make the timeing correct not #1 when the dots line up on the timing gears 4.3 is a good example i don't know what you have but you should check this

That motor has a timing chain, not a timing belt. Replacing it requires removing the water pump, dropping the oil pan, removing the balancer and timing cover. Rotate the crank so the dots on the cam gear and crank gear line up at the 6 and 12 o clock positions respectively. Unbolt the cam gear and remove it and the chain. If you need to remove the crank gear you can use a three jaw puller or something similar to pull it off.

It may be necessary to remove the valve covers and rocker arms as well to rotate the cam shaft if need be.

Verify that the distributor rotor is pointing directly at the #1 cylinder spark plug wire tower on the distributor cap, with engine set to TDC on the compression stroke for the #1 cylinder.
If not, and you have not touched the distributor previously, you have not set up the valve timing properly. Recheck your timing gear and chain alignment marks.
Hope any of this helps you. Good Luck!

There is a dot on each of the gears one on the large cam gear and one on the small crank gear.The crank gear dot on the teeth of the gear should point to the 12oclock postion straight up then the one on the cam gear point sin the 6 O clock position so the dots meet each other then you put the chain on the cam gear then around the crank gear then bolt on the cam gear the dots should still be lined up with each other.this puts the engine in the #4 firing postion

Just wrap the chain around the gears and lineup the dots. dot to dot and put them on. That's how it goes. The timing itself is not adjustable. It's controlled by the engines computer. It's that simple.

there will be two highlighted or dotted chain links for the camshaft and one for the crankshaft gear, position cam dot/TDC indicator in the 12-O clock position, the two dotted links should be on ether side of cam dot, turn crank dot to the 6-O clock position and line up highlighted link with dot on crank gear, if timing cover is on, then make sure cylinder 1 is at TDC when the two links are at 12-O clock.
