Question about 1983 Chevrolet Chevy

1 Answer

Timming seems to be off--its back firing

I have no way of setting the number one piston to the top.
if i could do that I'd have no problem setting the distributor.
i have a 1981 Chevy Van 1/2 ton with a 305 motor.
i cant even take the valve cover off there''s to many hoses.
i cant even pull the motor.

is there any other way of putting the piston to the top

Turn the engine by hand till the timing mark on the pulley is aligned with 0 on the timing scale (right side of pulley) If the rotor is pointing at the rear of the engine, turn one more time...it is now pointing at #1.
cylinders are 1,3,5,7 on drivers side, 2,4,6,8 on passenger side (front to back) Order is 18436572.

Installed a rebuilt cylinder head set timming to all data and mitchells timming book wont start blowing back threw intake


Sounds like your timing is out 180 degrees. Recheck by making sure #1 piston is on the compression stroke, then retime.

IS SETTING THE TIMING AS SIMPLE AS GETTING THE TIMING MARKS LINED UP? IF SO I HAVE DONE SOMETHING WRONG ANY SUGGESTIONS WOULD BE APPRECIATED


You have to make sure the engine is at top dead center on number one cylinder (all valves closed on number one cylinder) - if distributor installed check that #1 is on firing position so is not on exhaust stroke and or remove spark plug and put plastic straw in hole to see if piston is at TDC (top dead center) ready to fire on compression stroke.
After setting timing always rotate engine 4 times to bring back to same location and that nothing like pistons bump into valves etc. and make sure that timing marks are at the location. If you install backwards on some engines the oil pump will not be in line to accept oil and will not get oil pressure - I believe this true of 3.1 chev or was it 3.8 I messed up on, lol

On a rebuilt motor how do you set the timming on a 350 chevy. Thanks.


firing order is 1 8 4 3 6 5 7 2 remove number one spark plug its always the right drivers side head..closest to the radiator turn engine crankshaft till the top of number one piston is all the way to the top or if you have help put your thumb over the plug hole sand have someone bump the engine over till the pressure in the cylinder pops your thumb free,,,check front of crank  harmonic balancer for timing mark if you need to move crank by hand till the mark lines up to the 0...or top dead center....then make sure distributer cap is pointing to number one plug wire if not remove dist and turn to the right position and install...if it dosnt go in all the way dont worry hold light down pressure on it  and just bump the engine over and it will drop right in place then recheck your settings and install spark plug start engine and adjust with timing light check your specs

88 gt fireing at the plugs but will not run i


Sounds like you have timming chain problems. You can check this by putting your harmonic balancer on the mark that shows top dead center or 0 degrees, Once you have that done pull your number one spark plug and see if the piston is at the top of its stroke. You can also check this by loosening the hold down bolt on your distributor and while you have someone cranking the engine over move the distributor one way and then the other. If the engine tries to fire then you have probably jump some teeth on your timming gear which is the result of just plain old wear. Be careful when doing this as to not get your hand in the cooling fan!!!! If your mustang has high mileage on it then this is probably your problem. I recommend a double roller timing chain as a replacement because they last longer. Good luck

Put the engine at TDC compression stroke , Thats when the valves are both closed on No 1 cyl and the piston is on its compression stroke .then align all cam and crank marks. set distributor/rotor button on No 1 cylinder (rotor pointing at #1 plug wire) . rotate engine 2 revolutions and recheck all marks. Fire away

Timing setting


No it should not make a differance considering the engine will be constantly rotating, because the engine must be on and at normal operating temperature to set the timing.

I need to find out where the # 1 wire location is on ther distributor cap and where it faces. on the cap where it would face, of to the side or in the back or the front.


In most vehicle's distributor caps it is marked clearly.
You can easily locate the # 1 on the distributor, alll you have to do is rotate the engine to its top dead center mark found on the front crankshaft pully, remove spark plug on the piston number one and six cylinder, by the help of the dip stick you will be able to note that the pistons are on top( you will have to put the dip stick in the hole of the spark plug).
It will be better too to remove the valve cover so tht you would thn be sure tht the # 1 cylinder 's valves are fully closed both inlet and exhaust thus it being on ignition stroke whereby the rotor in the distributor would be on the # 1 wire, this explanation is taking into account the valve timming hasn't been distrubed.
Hope this helps!
