Massey Ferguson 235 (Ursus 2812) leaking coolant fast into the block

So first of all hi!
I'm new here and joined because my engine block is broken and I'm looking for advice. I have a Massey Ferguson with a perkins 2.5 liter diesel non turbo.

We have this 3rd hand tractor now for 30 engine hours and suddenly the temp sensor went to 0. The coolant was gone en the engine oil was a thick dark grey/black mayonnaise. I've worked my fair share on mopeds/motorcycles but not on diesel or tractors.
I figured out that most likely it was the head gasket that was leaking/blown although the engine was running great with a clean exhaust. No white or black smoke or lack of power.
I fixed the head gasket, cleaned up the head, new gaskets but the water appears to be leaking way lower in the block...
  1. The coolant leaks fairly quick if I fill it with 10 liters of water as a test than at least 3-4 liters is out in 10 minutes. If I fill the hose to the water pump it doesn't leak, but If I fill the intake to the block it leaks fast. (see picture)
  2. So my question is now is the only option left that my carter or cylinder block is somewhere cracked that I couldn't see from the top? The cylinders /piston look fine from the top a bit carbonized as the air filter system was a bit clogged up but nothing serious.

Any tips ideas?

Sounds like a cracked block but.....the water pump is bolted to the timing cover with a plate in between. This plate may have corroded through and in turn the front of the timing cover,allowing water into the timing case and the sump.
Remove the water pump and see.
(If it is the above, I'd have thought pouring water into the pump hose would see it run into the sump as well but you need to check it anyway)
 
Thanks a lot for the reply.

I've just unscrewed the pump and it doesn't look too well, but there is no big hole. There are corrosion damages on the timing gear cover, and the gasket practically no longer fulfilled its function, it was very used up and 'eroded' (I attach photos). In addition, inside the thread, where the screw fastening the pump on the timing gear cover goes, was this mayonnaise oil (in the place where the gasket was damaged the most), which definitely should not be there. I also showed it in the photo. Could this condition of the timing gear cover under the pump and the gasket be the cause of the leak or I still have to look for faults in the block?

Also should I buy a new timing gear cover or is the old one still finish?
 
Here are the mentioned photos

The timing cover is not in great shape but I'd be inclined to remove it and hold a torch behind it to see if there is light going through and run a jet of water to one side. If nothing, you could refit it and cover it well with instant gasket (albeit temporarily),refit the pump and remove the sump,refill with water and see were it runs from.Even better to pressurise the system.
 
Hi, thanks for your reply.

so we can only take the cover off in this engine if we have a motor lift, unfortunately. Is metal epoxy or lead an option?

2nd option is too simply go to the garage get a timing cover what is quite cheap 30 euro's + labour and let it be done in the garage...

The cover doesn't look bad enough to let the amount of water through that you have said,but it would be better replaced anyway,but also a pity to replace it and find it not to be the main problem......I guess an epoxy would be a temorary measure,if you can get it sanded smooth enough for refitting the pump.
Can't you support the engine with a jack and wheel away the front axle to give full access to the cover.Replace the cover,then put the jack below the transmission and remove the sump.Temporarily fit the radiator,refill and preferably pressurise the system. A leak should show somewhere...........

We used a product on a small diesel engine with a cracked block called 'steelseal' or something. Not cheap, but it's worked well for 12 months. It's not on a high usage machine though.
 
Alright seeing the answers i prefer to do the right thing and just bring it to the mechanic let him replace the timing cover with an engine lift and then I will put it all back together :)
