To be perfectly sure where the number 1 cylinder fire is at this point remove the valve cover, remove the #1 spark plug, remove the distributor cap, clean the crank to identify clearly the crankshaft marking on the crankshaft harmonic balancer wheel.
First step: Slowly turn the crank by hand until the line on the crank lines up to the zero timing mark...if you are on #1 the rotor in the distributor should be facing the #1 segmant in the distrbutor caps firing sequence, to verify further both intake and exhaust valve rocker arms should be in the valve closed positions in the #1 cylinder, the piston should be all the way to the top opf dead center(carefully insert a long skinny screw driver into the #1 spark plug hole to feel the pistons top travel while being sure the valves are both closed as explained above).
With all that checking out you are now exactly on top dead center in the #1 firing order sequence of your valve timing.

Why is my 1980 Chevrolet chevette going through so many alternators? I've replaced it going on 5 times


you must need to charge balance. Run the scanner /computer and the system will indicate if you have some electrical overload in the system and fix it.
God bless you

Where is the rotory button suppose to be pointing when the number 1 piston is up for a 1980 chevy luv


When #1 piston is up the rotor can be pointing to 2 different places. For every 1 turn on the crankshaft the camshaft turns 2 times. To be sure that the rotor is in the right position to fire #1 spark plug you need to remove the valve cover and watch the valves as you turn the engine. To be correctly positioned the intake valves have to be open and stasrting to close as you turn the crank to align the timing marks (TDC). As you pass TDC the intake valves are closed and the exhaust valves start to open. Back up so the timing marks line up and this is where the rotor is going to fire #1. If this is not what you are seeing, then simply rotate the engine 1 complete turn and you should see it happen then.

Unless you have changed the timing chain or removed the distributor this shouldn't be necessary.Perhaps if you suspect the truck has "jumped her time" then this could help to confirm. If you are doing routine maintenance, plugs, wires, cap and rotor then you don't need to be concerned that the timing marks line up but not the rotor button. Hope this helps.

Need timing marks for Daewoo engine in Chevy Aveo It is a1.6 liter double overhead cam


The crankshaft gear has a triangle timing mark on it. On the outside of the gear near the teeth. This points straight down, and lines up with a notch, on the bottom of the rear timing cover.

The camshafts have a mark on the outside of the gear, near the teeth. The camshafts are turned, so that the marks are to the inside, (in-between the gears), and the marks point to each other.

Timing 1980 vw pickup


You can remove the #1 spark plug and get the piston at top dead center, (all the way up in the cylinder). You can also check the access hole in the top of the transmission housing, to line up the TDC timing mark on the flywheel to the transmission housing. The mark on the crank pulley is rather hard to see, just a little mark "V'ed" into the pulley lip.

Check engine compression. Those engines have a cylinder arrangement that looks like four drinking glasses sitting inside a cardboard box. During overheat, cylinders drop below deck height and do not seal against gasket. Non-technical repair was to draw file the deck 'till it's even with cylinder tops.
Obviously, check all of your work as well, you may have inadvertently knocked something loose that has to do with starting.

There are timming marks on the cam gear and crank gear, you can use a strate edge to chk. to see if you got them lined up right, there will be a mark on a tooth on one gear, and the other mark will be between two teeth. just line them up and you got it.
