Ford 3 Cylinder in Sanderson Forklift - Water in Sump

got my budget boroscope in

The question is, after cleaning, what will seal that porous cavity best?
Epoxy “liquid metal”, or some sort of sealer paint?
It needs to stay stuck on and retain a bit of flexibility, and cope with heat and antifreeze. Gravity is on my side as whatever is applied will sit in the cavity while it sets.

Tiger seal

Oh and while your at it with head off, change the core plug in the top on the head under the rocker cover, they rot from the inside

Oh and test or fit a new rad cap

Tiger seal

Windscreen bonder cleaner first then the black primer paint. Then tiger seal?

Tiger seal on it's own wont get in the crack but the black primer paint will and will then set?

I doubt tiger seal will stick well enough on it's own and dont rate its chances much in oil or antifreeze imo long term?

@DrWazzock a full windscreen bonding kit with primers is about 20 to 25 quid on ebay.

Tiger seal is basically same as windscreen PU bonder! Or panel bonder.

Any epoxy wont stick that well and crack off as too rigid in my opinion.

Or thinking about it you can get special paint for engine castings and in side gearboxes to stop sweeps and leaks though pores and cracks in aluminium! My mate did the inside of a aluminium crank case on a 100 year old french car not long ago.

I think he bought it from frost?

Looks abit like red oxide imo but it's not.

Quite thin and you build it up in layers. Think he did 3 coats?

@DrWazzock this was it. Problem is you would need to get the area spotlessly clean and free of corrosion.?‍

I thought that showed promise. Thin enough to get into cracks and pores. I have had some success with SAS liquid metal on grey Ferguson blocks but surface prep was easier with liners out of block.
Almost tempted to try a good lathering of Hammerite.

If machine was mine it would be long gone
And probably replaced with Chinese loader

Myself and a mate has done 2 engines, and tiger seal dose work, as we did that and it worked, I did say earlier to clean with brake cleaner and compressed air
And it's fine with antifreeze

Fitted a longer shaft on my dremel and reached down into the block and cleaned up the porous area with a deburring bit. Finally pudged in some SAS liquid metal 380. A bit messy, not as neat as I’d like, but I think it’s covered the suspect area. It’s held hot water for two hours but not pressurised. Time will tell.

Got it all back together at last. Warmed it up and gave it a run. Put some k seal in for good measure. Retorqued head bolts and set up valve clearances. She runs well enough though the pistons are a bit blowy. Not lost any coolant into the sump after 2 days now. Fingers crossed it will hold for a bit and load another few thousand tons. Not bad for a 45 year old machine.

Interesting. Thanks. Happy to report the Sanderson has loaded another 600 tonnes of beet this season with block patched with “liquid metal” epoxy. Long may it stick.
