1929 special coupe

[JohnLaVoy]

Welcome to the hobby, hope to see it on the road soon!

[LSJUNIPER]

Thank you all for the comments. I think this is going to be a fun project.

I have been adding Marvels Mystery Oil to this motor off and on since August. Still stuck, will not move... Should I continue letting it soak in the oil or should I take the head off and see if it can be freed up by tapping it with a piece of wood???

Great looking car. I hope you enjoy yours as much as I do mine, John

[Barry B./ Ma.]

Congratulations on the Special coupe, these were only made for one year (mid 28 to mid 29). Good luck and if you have questions don't be afraid to ask. I did mine over from scratch in 1981and it's still going strong.

You should pull the head off.

Mix ATF and acetone. That will get it unstuck. Mix it 50/50.

How long since the engine last ran?
Any chance you could borrow an inspecion camera to look inside the cylinders?
There is a tool made that fits in place of the starter which is the best way to try to move a stuck engine. I wouldn't wrench on the front crank bolt, or at least not more than the usual amount to hand crank the engine.

If you don't know how long since it last ran, then it would probably be best to remove the head.

[LSJUNIPER]

The last time it ran was in 1975,,, Wow I was 14 years old!! LOL
bart78, Is the ATF transmission oil???

[700rpm]

If you have the belt molding that goes around the back of the cab, be very care with it when you remove it. They are extremely hard to find and expensive if and when you do. Also, don't throw anything away, no matter how nasty it looks, and use original parts whenever you can. Take lots of pictures.

Yes, auto tranny oil.

Best to start a new thread to keep this from getting mixed in with the original thread.

[bart78]

Yes it's auto trans fluid. And I have seen it unstick all kinds of nasty stuff.

[LSJUNIPER]

Will try it this week when I get a chance... Thanks for the advise!!

[somethingspecial]

Welcome , I have a 28 S/C if you look in my avatar in albums I have pics you might be intrested in

[LSJUNIPER]

Motor is still stuck! Took the valve cover off and it looks good in there, not rusted up. Then I took the head off and it also looked pretty good. So what’s my next step??? Can the starter be causing the motor to not turn???
Here are some pics of of what I have taken off of the car so far…

Before you even try and start it , get rid of that bent looking fan & copper gas line..

[Mitch//pa]

yes it can ,, loosen the starter bolts and the starter should easily come loose.. also if someone put to long a starter bolt in it will wedge against the flywheel

[Tom Wesenberg]

You might get lucky and can unstick a jammed starter by shifting to 3rd gear and rocking the car forward.

[Barry B./ Ma.]

Put some of that ATF around the valves as the stems can be stuck in the guides. When you remove the starter try to work a long pry bar between the teeth and see if you can break it free by going back and forth. Don't use too much force as you can damage the teeth. Have you filled the crankcase with new oil?

[Fred K-OR]

What did the oil look like or have you drained the oil out of the engine?

If the starter stuff mentioned above is OK, I have unstuck engines by taking a short 4x4 block and tapping on it after setting it on top of the piston. But do not tap to hard.
