Genset block with rust pitting in bores

[Ab4875]

Is this worth bothering with or is the pitting too deep?

Hey mate,that first pic shows some pretty deep pits.....it'd be worth your while to clean out all the dirt and rust with a bearing scraper to see how far gone it is. What is your plan with it?, try to use use it or just keep it for a spare ?

if the block is not cracked the eng is worth haveing it sleved

That may be a keeper!! Check this thread and compare to your engine.

That appears to be a 99A or one of the other 239 type truck blocks. They have the thickest cylinder walls of all the different flathead blocks. If the block isn't cracked and has enough meat left for any of the large pistons available for flatheads, then it is well worth saving. They can go all the way out to 3 3/8-inch if need be. I'd shoot for under 3 5/16-inch if possible.

I've saved blocks in worse condition than that. If their not cracked, get them baked cleaned. A .060" overbore will clean up even the worst rusty cylinders, deck the block and you should have a runner.

That's interesting on the round centre water passage. These were also lying out in the open. Would they be worth keeping? They have probably been exposed to the elements 10-20 years. The two on the right side have the round centre passage.

This is a different engine. I pulled the intake manifold and found this crud. Would this be a problem? I'm not sure if it is corrosion debris from the alloy intake manifold or something else.

Is there anything worth keeping amongst this?

It's all worth saving, if you have the room. The blocks and flywheels especially. There's such a lot of problems that can render a block useless, or at least difficult to bring back to life, that it's good to have as many cores as possible to sort through to find one that can be rebuilt. Manifolds can crack, so having uncracked ones to hand can be useful.

It depends on your circumstances, (space, time, money) but if you can get the blocks and some of the other parts out of the elements it would probably be a good move.

If the blocks are surrounded by a pile of parts make sure you sift through and get the main caps. Things like oil pans and starters are worth getting too. Even small stuff like the original ford bolts and hardware is worth saving. It's normally better quality than the modern stuff.

I would be tearing those engines down, checking the blocks for cylinder wall thickness, cracks, etc., and also checking all components for keepers. Even though those engines and other parts have been exposed to the elements for some time, there should be plenty of stuff that's salvageable there.
