Engine save or replace?

[wichitakid]

I have a 78 2F in my 1965 FJ40. I removed the water pump and saw this behind it. It looks pretty badly corroded, but I'm not a judge to know if this is something that will prevent the engine from ever working (it ran when I got it). I can break the engine down some more and see what's inside (not my expertise), but I wanted some advice as to whether I should just shop for a used 2F now and save myself a headache. Any help is appreciated.

Linky no worky...

 

[oldschool4wheeling]

Yep, no worky

 

[wichitakid]

Apologies.

Needs flushed for sure; not sure about condemning the whole engine though. Do you know what the compression is like?

 

[bikersmurf]

Stuff a rag in the whole, scrape the surface clean with a wood chisel, reinstall the water pump, and flush your cooling system.

I'd not be too concerned about the scale if the motor runs well.

 

[wichitakid]

All I can attest to is that it ran when I got it, I don't know how well it rain. No idea about the compression numbers. My concern here is really is it going to keep corroding more, and am I going to have to do some more work, or can I clean it up and replace the water pump and move forward with work on the rest of the truck.

 

[bikersmurf]

If you use antifreeze, it'll minimize future corrosion. It's an old truck, it'll need some love to make it purdy again.

I'd wager the rear drain is all plugged up. when flushing you'll most likely need to use a small screwdriver to open the rear drain to get the fluid out.
I'd do my best to get as much out now so it doesn't go to the radiator.

Wood chisels are for wood. Wire wheel it with an angle grinder.

Isn't the motor made out of wood?

 

[Cruizerjunkee]

must have been using Dex-cool

 

[bikersmurf]

Wood chisels are made of good steel and work well for cutting & scraping steel. Use a cheap/beatup old set and sharpen when they get dull.

Wire wheels don't really do as good a job.

Very much agree! From an old wood butcher, I have used older chisels many times for gasket scrapers. With careful use they will do an excellent job of cleaning the gasket surface. They work very well, and can be re-sharpened easily for going back to use on wood.

This is what the water pump looked like when I removed it. Assuming that the opening doesn't crumble when I clean it. I'll take everyone's advice and reinstall the water pump and move forward. Thanks for all the replies.

X 2 on 3_puppies comment. Opening or removing the block drain will tell ya a lot.

Clean it up, I would use some Permatex Gray on the gasket, flush the cooling system a couple of times and run it.

 

[Cleg]

I'd go with plan A and plan B.

A) Flush it out with a garden hose until you can't get any more crud out of it then run it.

B) Keep your eyes open for a deal on a spare 2F.

Wow, that's interesting... I can only imagine what the engine block interior water channels and radiator look like! Probably time to chuck the pump. Is there something that may dissolve that crap? Looks very constipated and probably has an internal blockage problem. ssgoat told me that if you give the cooling system a good strong hot water Dawn detergent enema it clears the crap out. But that??? Hmmm.

 

[Tools R Us]

Looks like an engine that has set, the coolant evaporated. Just a water soak, or possibly adding some cooling system cleaner, should get most or all of it out.
