Martin, you don't understand. All of these engines are over 50 years old and just waiting to self- destruct. You shouldn't rebuild your own engine because, 1) you don't have the tools, 2) you don't have the skill, 3) you don't know how to use a torque wrench and 4) there are no parts left to fix whatever is broken. Now sign the titles to these cars and send them to me. I will hopefully be able to dispose of them for at no additional cost.

Disclaimer: I rebuilt my first 356A 1600 Super engine on a milk crate in a carport. It wasn't easy. I had to replace the roller-bearing crank and rods with plain bearing units. I burned a piston 25,000 miles later, so I probably didn't know what I was doing........
Some days it's just not worth chewing through the restraints.....

Removing all 4 spark plugs and trying to start it will take less than 15 minutes and tell you quite a bit. If it still doesn't roll over, the motor has to come up. If it does crank, then you've got a weak starter or high compression.

Wes it’s true- I am clueless, but on my recent rebuild I have over 300 miles and it still runs!

engine barely turns over and putting engine in

#35 Post by David Trower »

I have just got back to looking at a few of my problema with my A engine.
Engine barely turns over as though the battery was nearly dead. Battery is new and tested.
I removed the A engine and put a SC engine in and it cranks just fine.
I am baffled and am going to take the A engine to my mechanic.

The other problem I have when putting the engine in is getting the top right bolt to stay in place as I push the engine in. The top left bolt is accessable but the right bolt goes in as I push the engine in. How can I get this bolt to stay in place?

Thank you to all that have written offering suggestions.

Keep us posted on the analysis of the A engine. Something is wonky. As far as the top bolt. Some silicon it in place, others may use body putty. I drilled a hole in the head for a roll pin so it can't spin when tightening it up.

I also drilled the bolts for a roll pin. I think that was Ab Tiedman's solution, he used to sell the bolts with roll pins installed. If the bolt slides to the front when the engine is installed, just reach up and push it back in place.

Magnet. Or do as I do: Cross drill the end of the bolt, slide the washer and nut down safety wire and use the safety wire to hold the bolt out.

Or my method, a few turns of masking tape on the bolt just below the head. It makes a nice press fit, works great as long as the threads are clean.

I reviewed this thread twice, but didn't find that David pulled the spark plugs to see if the starter spins the engine easily. (Sorry if I skimmed right past that ...)

David
did you get your engine to your rebuilder to put it back on his test stand to see / find out what the problem is ?

I really do give up asking what stopped Dave installing his engine. The Above Posts are reference to an engine that WON'T TURN OVER !
Yes ?

Easy way to get the top passengers side bolt to stay until you have a washer and nut on it is to just stuff a rag against the head of the bolt up there in the no mans land/blind caviaty- but be sure to remove it after you have finished. I do like the bolt head with the roll pin in it or a hose clamp around it though.

I’ve both emailed and talked on the phone to David Trower. He seems like a fine fellow, I guess just not keyed in to the forum lifestyle.
