1922 bent push rod What do I do?

Hi Forumites!


It has been a long time since I bothered any of you. So, I thought I would check back in with a problem (of course).


A few of you might remember I bought a chopped off 1922 4 cyl touring to make a speedster.

It has 14,000 miles on the odometer and has not been started since it was put in dry storage in the 40's.

Story is, before a young soldier went off to war, he removed the high tension wire from the coil to the distributor and locked the ignition.

He did not make it home. His parents could not bring themselves to sell the car. It sat in the barn until there was an estate sale in the 70's.

I neighbor who always wanted the car, bought it to make a roadster. he cut off the back part of the body and put it in a shed without trying to start it.

He turned 80 a few years ago and decided he was never going to finish the car and put it up for sale on Craigslist.

I bought the car. The ignition is still locked and the high tension wire is missing.

It has not been started in 75 years.

The tires still hold air.

I removed a 5 gallon pail of mice nests packed around the flywheel and clutch.

I drained the oil and replaced it with new oil laced with MMO.

I dropped the pan yesterday and there is an 1/8" of very wet sludge in the bottom.

Not bad!(pic)

I have never seen a "new" 1922 crankcase, but this looks like one to me (pic)

When I turn it over with the crank, I get almost 30 lbs of oil pressure!


The problem is a bent push rod. (pic)

I have read that usually means a stuck valve.

I have reached the level of my incompetence.

What would you suggest I do?

Thank you all for your guidance. I really appreciate it.


I have been soaking the possible offender with penetrating oil for several days.

It has also been soaked in MMO for several years.

I will try the rubber mallet.

If it does not move, I will remove the rockers and try the ball peen.


Does anyone have a method to straighten out the bent push rod?


P.S. Morgan. I have really enjoyed the restoration videos you have made with your '18.

       They are a big part of the reason I have gotten back to my '22. Thanks

    You do not straighten push rods.  You replace them.  Someone will have one for you.  You just need to do some looking and have some patience.   

So by that I also mean that you do not want to install a new push rod and then bend it.  Here is some more food for thought.  

Remove the bad push rod.  Take a rubber mallet before you turn the engine again and ensure that each valve spring moves (some) when you hit it.  Turn the engine say 15 degrees.  Tap all the springs again.  We want to make sure all the valves move before we do any crank rotating.  Before I forget, make sure the water pump is not frozen to the shaft also before rotating the engine or damage will result to the camshaft  gear.   Once you can make a complete rotation, then you can measure one of the valves springs, and see how far the spring needs to be compressed in normal operation.  You can make a lever arm to push on the stuck valve once it is free and ensure that it will move the amount it needs to move.  Only push on the area above the valve stem.  Once the amount of movement is verified, then you can replace the rod.  

I will also weigh in that the safest thing is to just pull all the valves out, clean out all the carbon and old oil, Ensure all parts have assembly lube in them.  Not a bad time to dress the valve seats and faces.

Good to hear from you again Dwight!

 Here is where I am at with the 1925-45 we worked on for John Brough back in March of 2013. He stopped at my house last Sunday to drop off a painting a relative did of the car back in 2009.

 Replacing the timing gear!

 To me the painting and the car are both "20 footers".

We were on our way to church about 1/2 mile away from home. The engine popped and barked and shut down. I tried to start but no luck. We towed it back home to put in the garage. The next day I did start it but there was a thumping sound that I thought was a rod going out.

 IT was not until we got the 25 Standard back together a year later that I looked into the Master again. After several attempts to restart and finding no spark and then going through all that trouble shooting did I find that the fan and water pump shaft was not moving. 

Timing Gear out….

 Dwight. Again if you are in need of help with the 1922 please let me know!
