So I've been trying to get my 67 1800 started, the previous owner claimed it fired up and drove two years ago, but it's sat since then. I've replaced the ignition with two switches, due to not having a key. When I hit the switch, it turns over one revolution, then theres a CLUNK, and the engine seems to be jammed up. It can't get past that point. Using a breaker bar, I can turn it past that point, but hit the switch, and it comes around and jams there again. Another pertinent factor is that it's -20 degrees celsius outside, and an improper antifreeze mix from a PO has resulted in the block being full of ice, frozen pretty good. Any ideas what might be the cause? I've taken off the head, and the symptoms do not change. Should I just try to get it thawed out and see if that helps? I LOVE working outside in the middle of winter like this lol.  |

Definitely thaw the engine out if you can. If the head is off, you should be able to turn the engine over on the fan belt, or by using a spanner on the bottom pulley bolt, without too much resistance.
If the engine is free using that method, I'd be looking at the ring gear on the flywheel as a starting point.

If you insist on working in sub zero temperatures, I would do something simple like take off the starter motor (just a remote chance that's the problem and it's relatively easy to remove) and see if the engine rotates by hand with the plugs out (not sure if the head is still off if so forget taking out the plugs!). If no success let it all thaw out and try again. Don't try and force it with a lever you don't know what damage you may be doing. Sounds as though it could be an engine out job sadly.
I'm now living in Thailand where the problem is temperatures that are too high to work in comfortably, but understand you can't just stop everything becaue of the weather.
Keep us informed, good luck, David

Thanks for the suggestions, things may just have to wait until spring. I just can't stand sitting around the house with a project car outside ha ha.
I suppose a few hours with a torch might help.
In the spring I'll have facilities to pull the engine.
Ya, I used to live in Indonesia, I sure miss the tropical weather when my fingers are freezing to the wrenches lol.

Here's an update to my starting issues. I thawed out the motor, but the motor was still stuck. So, I pulled off the starter motor. Once that was off, I could turn the engine by hand quite easily, so the rest of the internals seem to be ok. also, the problem appears to be with the starter motor, or flywheel ring gear. I inspected the ring gear all the way around, it looks ok, no damaged or broken teeth. Here's my starter  The business end:  I connected it to a battery, it spins great. the gear screws in and out easily by hand. Not sure how this clever little mechanism works when it's in the car, or what might possibly be malfunctioning. Anyone got any ideas? |

Called the bendix.
Spring is either weak or some grit has caused it to stick. Clean helix up, replace motor and try to start again. If still jams replace spring or starter motor.

When you run it out of the car does the bendix gear spin out? if not oil with a light oil.
If it was causing the engine to lock up it must have had the bendix partilly engaged.
Before trying it again to start the car, replace it with the bendix fully back and try turning the engine over by hand. If its free then try the starter.
Regards Kels.

I cleaned it up with WD-40, put it back in the car, and it seems to be working. Now I just need to put the rest of the engine back together. Wish I'd left well enough alone...  |
