Leaking water from the back of the cylinder head

Hello to all,


This is probably covered in the forum but I simply canít find it.


My 110 TD5, with 180.000 KM, is leaking water from the back of the cylinder head.


Iíve took some photos just to illustrate, and from the parts catalogue I can see itís the Plug Core Ė 37D2260L.


The questions I have are:


Is this normal with this KM?


Can it be replaced without taking the head off?
(what do I need to replace it)


Does this mean thereís also a problem with the head gasket?
Ö


Thanks in advanced.


Regards


Frederico

Could it be the rocker panel gasket?

I’m sure it’s from the plug.
Does anybody know if there’s any product, like a sealant, we can apply from the outside to simply stop the water from leaking?

Any sealant that can plug the leak from outside is likely to plug the heater core or radiator, or worse. Sorry.

You could try a coolant "stop leak" but those are only temporary and can plug heater cores "bars leaks" brand is my preference and is not supposed to clog heater cores, but I still wouldn't rely on it for long term service.

Better bet would be a rubber expansion plug. And a spare one in the cubby.

But the only real fix is to pull the head and change the plug.

Thanks to both,
I’ll definitely go for the plug change.
Can it be done without removing the head?
What kind of sealant must be applied to the new plug?
Regards
Frederico

That's a freeze plug. It's probably rotting. Get a replacement.

The plug swap itself is no that hard, it's the location that makes it really difficult.

Replace the frost plug with new one. If you were stuck in the bush I would recommand PRC. It's an aircraft product like silicone with extra strength. Used it over water, gaz, diesel or what ever. It's a bitch to remove! But if you can repair it properly, why get to all this trouble?

My two cents..
