I tore apart the four banger on my 1924 Chevy truck that has been sitting got 20 years. Now I have to make a decision on whether to scrap the engine or rebuild it. Maybe someone can give me some advise. Here is what I found:
Rear main bearing in three pieces. 1 rod bearing shattered. Cam lobes flat. Exhaust valve seats burnt down till head material is missing. Valve stems rust pits. Pressure plate rusted solid but may come apart eventually. Clutch burnt till rivets gone and plate broken. Water pump   impeller rusted away. Needs points and rotor. Carb also needs rebuilding.

RickAlter; If the head is no good, have fun trying to find another one that is not cracked. Otherwise i guess it would all come down to price. Just about anything can be rebuilt.

From Rick's first thread, the truck looks like a '26 and the engine is a '26 or '27 with a '28 head.

Rick, FYI, a '26, '27, or '28 engine will bolt right in. At some point in the truck's life, someone definitely replaced the head with a newer model. A lot of the 4 bangers have the '28 head on them. It is the only 4 cylinder head with two exhaust ports.

Cheers, Dean

28 heads are not that difficult to find. At one time I had 13 of them still have several in a stack. Other years are not so easy to find. Have to find a '28 exhaust manifold if you don't already have one. They are out there as well.

Being retired with not a lot of income coming on I'll probably just sell the whole project.

Ok. I found a 4 cylinder chevy engine out of a boat almost fits exactly. I will have to put a powerglide transmission on it. Has anyone had any experience modifying the enclosed driveshaft to an open one?

You would need to put a modern rear end in it.

I have decided that I will definitely rebuild the original engine. The head was taken to "Harry's Heads". He said the head was easily rebuilt. I ordered new valves and he will be making new seats and guides. I took the rest of the engine apart and he now has the block to boil out. One main bearing is cracked in several places as is one rod bearing. He said there is no reason not to use the cracked bearings. The engine doesn't turn high enough to be concerned. Does anyone like to make a comment? Also I am going to need rear fenders. I am going to make it an original tow truck as seen in the Weaver auto crane truck flyers.

my 28 had 1 cracked bearing when i rebuild last year.



it was a pain but I was able to get a new Babbitt poured. There is a factory near me that makes windmill bearings and apparently, they are Babbitt bearings in those giant windmills today. So, I got some Babbitt material from a guy who works there and he poured a new bearing then a machine shop builds a jig and turned it down on a lath to the proper thickness.

I found Tom Ross in Omaha who does all kinds of engine work including babbet bearings. I have given him the block, crank and rods. When I get it back the crank will be in the block which will be bored with new pistons installed. It's great to see these kind of guys still exist.

Is there any type of engine parts or overhaul/repair manual available. It won't be long and I'll start putting the engine back together and it would sure be nice if I was doing it properly. In the aircraft engine rebuilding area I always had an overhaul manual to use.

Hi Rick,

Yes, you can buy reprints of the original shop manual from a number of vendors, like the Filling Station.

For more info, in the members area of the VCCA's main web page, there is a technical resource area. Inside there is a wonderful document written by Ray Holland on his rebuild of a '28 engine. It is well worth the minimal expense of joining the club just to get access to that document.

Of course, you'll get many more benefits by joining the club. Another biggie is being able to use the Chat Search Function to find previous discussions about working on these fine old vehicles.

Cheers, Dean
