Usually an ASD relay or ignition switch will go bad and keep it running when you turn the key off. Or, sounds like someone mismatched the ACC and 12v wires somewhere in the harness or something. It's worth getting checked by a professional.

It's easier to remove the speedo part of the dash, screws on top of cluster and around steering column, I can't remember where all the srews are, as you pull it out, reach behind it and unclip the cable, there should be an electrical connector also, now you can reach the cable. I can't remember if the steering column need to drop down, I guess you will find out.
Sorry it's been awhile since I worked on that old of car, but I had a 73 - 442 good luck

What you speak of as to the left blinker doesn't flash, yet the instrument cluster shows the green arrow (to the left), and yet that and the left turn signal lights do not flash, appears to be a simple burned out bulb. If one of your left turn signal bulbs are burnt out, then the #552 Flasher Unit in your fuse box is NOT the cause. It's the "Amperage" not being correct to the flasher unit. Place the parking brake on and start your vehicle. Put the left turn signal on and check to see ALL the bulbs are illuminated for the left turn signal. If you find one bulb that is not illuminated, then replace the bulb. It should be an 1157 bulb, but in the front it could be a 1157 Amber bulb dependent on whether your turn signal lens is clear or yellow.

If you still have difficulty finding the dead bulb, turn on the right turn signal and see which bulbs are illuminated and this will give you an idea as to which bulb on the left side isn't working, or turn on your Emergency Flashers which will turn on both the left and right side lamps and see which bulb is not lit up.

I hope this Helps,

The cause may be from worn valve seals on that bank of the engine, and oil enters the combustion chamber fouling the spark plug(s). A Compression test will be needed to verify if it is the seals or piston rings not sealing.

Sounds like it has jumped timing. Check to make sure all wires are in correct spots, then see if distributor is loose enough to turn by hand, rotate it as far as it will go one way and try to start, if not go the other way and try. If it gets better one way or the other, you may have jumped time and need new timing chain or distributor gear.

On your heads you should have 5 pairs of head bolts. Start with the middle pair and tighten the bolt under the valve cover first. #2 is directly below #1. #3 is to the right of #1. #4is directly below #3. #5 is to the left of #1 and #6 is below #5. #7 is left of #5 and #8 below #7. #9 is extreme right past #3 and #10 is below #9. Tighten the bolts in 3 stages to a torque of 85 ft.lbs. Hope this helps.

1966 Olds 98?
It's been a while, so bear with me. The main objective is to remove the steering wheel, to have access to the turn signal switch.

1.Negative battery cable disconnected

2.I believe you twist the horn button in the middle of the steering wheel, and pull up, to remove. The horn button should have a ring of thick rubber on the bottom, which keeps it in the steering wheel. The chrome piece under the horn button may come off with it, or it stays on the steering wheel. This is the part that is fuzzy to remember.

3.Remove the steering wheel nut, and lock washer.

4.If you do not have a steering wheel puller, go to your nearest auto parts store, and see if one is available to rent. The cost of this puller is relatively low, so you may just want to go ahead, and purchase one. While you're there you need to obtain another tool also. Steering Wheel Lock Plate Tool.

5.After the horn button is removed, and the steering wheel nut, you will see a flat metal area of the steering wheel. On each side of the threaded part of the steering column shaft, there are two small threaded holes, in this flat metal area.

The steering wheel puller, is a bar shaped piece of metal, that has a threaded hole in the middle. There is a threaded shaft that goes into this hole. On each end of the metal bar are slots. Threaded bolts go through these slots, and line up with the two threaded holes in the steering wheel. There is a pointed tip, that rotates on the threaded shaft, of the steering wheel puller. This pointed tip goes in the middle of the steering wheel shaft. (The shaft that you removed the nut from)

Find the two correct threaded bolts in the steering wheel puller kit, that matches the threads in the steering wheel holes. They HAVE to be the correct size, AND the correct thread. (Fine thread, or Coarse thread. They will be SAE thread, and not Metric) If the puller does not come with bolts, or the correct bolts, you'll have to purchase them separately.

Place the puller on top of the steering wheel shaft. Run the threaded shaft of the puller down, until at least 3 to 4 threads of the shaft, are showing on the steering wheel side. Now place a threaded bolt in the slot on the outside part of the bar.

Run the bolt down into the steering wheel threaded hole on one side. Make sure it goes in at least 1/2 inch. Do the same with the threaded bolt for the other side.
Adjust the length of the threaded shaft of the puller, so that the two outside bolts will go in as advised. Adjust the threaded shaft out, or in. Be SURE the two threaded bolts, are threaded down into the steering wheel the same depth, and the bolts are the same length!

Now turn the threaded shaft of the steering wheel puller in, with a ratchet and socket, to remove the steering wheel. (Turn the shaft to the Right)

6.Now remove the steering wheel lock ring. The steering wheel lock ring tool is now used.
There is a cylindrical shaped piece that has threads on the inside of it, and has a hole at the top, that a lock pin slides through, for the above tool. This cylindrical shaped piece is threaded down onto the steering wheel shaft.

The tool has a handle shaped like a screwdriver handle, and a shaft attached to the handle. The shaft goes down into the cylindrical shaped piece. Then the lock pin goes through the cylindrical shaped piece, and also a hole in the shaft of the tool. This lock pin locks the cylindrical shaped piece to the shaft of the tool.

BEFORE the cylindrical shaped piece is pinned to the shaft, you slide a U shaped piece up on the shaft. (Thought it would be better to explain it this way)
The opening of the U, goes down towards the steering wheel. It's U shaped to clear the steering wheel shaft.

As you turn the handle of the tool to the right, it pushes the U shaped piece down. The U shaped piece then depresses the steering wheel lock ring down.
(There is a Thick metal spring under the steering wheel lock ring)

You have to take a metal pick, and a small flat tip screwdriver, and remove the round snap ring. May take a little finesse, and a few tries. Use patience. Now back the steering wheel lock ring tool off. (Turn to the Left) The steering wheel lock ring will come up, so that you can take it off. Remove the spring. Remove the plastic horn contact assembly. Now you can see the screws to remove the turn signal switch.
