View Full Version : ENGINE RESTORATION and the 5w's

07-29-2013, 04:26 PM
Ok I'll keep this short.
Has anyone ever seen a post about a guy that was restoring a wooden boat and the engine was seized so he put it into a bag and poured oil all over it and what have you.
He bagged it for a decent amount of time. I believe it was like two years. I'm wondering if anyone has ever seen this Thread or Story online somewhere. I knew I should have book marked it. IF anyone comes across this and have the link, post it; I would love to see that project again. I'd like to show someone hence why I'm looking for it.

What do you mean by "seized"?
Seized usually means a lack off lubricant or excess heat has caused destructive metal to metal contact. Damage like tat is taken apart all the time because seizures are usually localized.
If you are talking about an engine injesting water and rusting everything in place I doubt the "bag of oil" trick would have a very high percentage of successes. I did a '49 Chrysler marine that was completely rusted and the tear down was long, tedious and certain items were accidentally destroyed and others purposely destroyed to get the thing apart. The fact that the crank can't be rotated is a big hurdle in itself.

I did a thread a fair while back about treating rusted engine components in molasses. I bought a seized engine... just seized from sitting around... freed it up with a mallet and a lump of wood.

Here's the crankshaft going in to a bucket of molasses - bearing journals protected with grease

Same crankshaft and some other bits after rust removal

Wow that motor that is posted looks rough! Nice that it got back to living life!
I'm talking about a motor that is in a boat at the moment. Its not a wooden boat and its not an old motor either. Its from a modern Proline Fishing Boat.
I would say the boat is late 90's. It was taken to a shop to see why it wouldnt start and what it may need. The mechanic there said its seized, now I find that hard to believe that the only thing left to do is scrap it!
The boat was stored indoors for its entire life, mind you the last time it touched water was probably 5 years ago. I still think the guy is nuts to say it should be scrapped. I say its possible to get it back to life.
Lets be real here, in order to know the severity of the seizure, if you will; you have to take it apart and inspect it. I know that didnt happen to the fullest extent. However that being said, I was looking for that thread with the engine in the bag because it was amazing what the man did to the motor. I'm telling you that it was worse than the red one posted above! It was unreal!

We need to know what type of motor it is and exactly what the mechanic was refering to when he said "seized".
If water got into the intake tract and rusted the upper end the motor can be gotten apart. If the crankcase and everything else sat with water in it you have a bigger problem and the damage may make rehabing the motor impractical.

I had a boat with a single cylinder volvo diesel. The Boy called it the single celled hammond organism. Well, the rings were pretty rusted up to the cylinder. Like yours, it had never been submerged, just left unattended for a long while. We used the boom and the spinnaker pole to get it out onto the sole, and tore it down, lapped the cylinder and put in new rings. Started right up, with new fuel and filters, oil, etc. Was running fine when we sold the boat.
To free the rings from the cylinder, we used a 2 x 4 as a lever, and some diesel poured into the cylinder and left overnight.

If my Hammond ever sounds like a Volvo diesel I'm tossing it out of my living room!

On a less strenous note, the morning after Judith and I met, she took me to Greenfield Village in Detroit, AKA very appropriately as The Henry Ford, where a Plymouth locomotive had just had its V-8 gasolene engine re-built. They were in the process of spending a hundred or so hours just letting it turn over. This was done with a V-belt and an electric motor. The Locomotive, BTW, is a gas-mechanical, that is, a gas engine powering the wheels with the help if a four-speed manually shifted transmission.
Colossal displacement on that engine.
