It can not be done with any certainty with out getting number one cylinder on top dead center and on the compression stroke.
Wherever the distributor rotor is pointing when the #1 piston is at TDC of it's compression cycle. When an engine comes from the factory it's supposed to always be in the same direction, but if the distributor has been removed and the person working on it wasn't too concerned, who knows WHERE it will be pointing. I can't believe that a distributor on a 79 has never been removed, so you'll need to find #1 TDC and figure it out from there.
== == need to set timing on my 1986 corvette after replace hei
there should be a notch to keep it from going on unless it is on correctly. i am assuming that it is the "rotator" under the distributor cap...
8º BTDC but the 1.8Liter 1ZZ FE does not have a distributor, it is 'timed' to spark by the ECU via the camshaft position sensor, to ignition coil on each cylinder, therefore not adjustable.
The distributor drive is a little shaft with a gear on the end of it that meshes with a gear on the crankshaft. Your first task is to be sure there's not one in there already. Stick your distributor in the hole where it goes, shove it in as far as it will go, and turn the rotor. If it meshes with something in there, you've got a distributor drive. Tighten the distributor clamp after you static-time the engine, and be happy. If you DON'T have one... remove the right-side valve cover. Turn the engine over with a wrench until number 1 cylinder (the one to the front of the car) is in firing position--both valves closed. Get a distributor drive, grease it up (it probably won't go in unless you do), and put it in the hole where it goes. Don't stick it in all the way. Put a rotor in your distributor, mesh the end of the distributor shaft with the distributor driveshaft--it only fits one way--and turn the rotor until the long, narrow end, which is where the fire comes from, is pointing at you. Now push the distributor down until it stops. If you have lived a clean life, the teeth on the distributor drive meshed with the teeth on the crank, and the distributor bottomed out like it was supposed to. No one gets that lucky, so just move the rotor back and forth a little and it will drop right in.
no
Yes, the defrost is supposed to run in A/C mode for better defrosting
I'd have to double check, but I believe the cam and crank timing marks are SUPPOSED to be pointing directly at each other to be on #1TDC. Just turn the crankshaft 360 degrees, back to TDC, then point the distributor at #1. You shouldn't need to change the timing chain adjustment.
This is a worldwide community to answer questions. You will have to define the meaning of "Mn". Is that supposed to mean something or was that a typo?
Yes Mine Has that to it's a 95.
The safest position is at home Ha Ha!! but blocking position is where you are supposed to ride which is close to the centre line where the driver's side tire on a car would run.
how am I supposed to know
