Help with water intake pipe on cylinder head

Post by vocinac » Mon 19 Jun, 2017 2:52 pm

Hi Guys,
I hope you can help me with my W111 head.
Water intake pipe was loose so I removed all of the plastic sourounding it and ended up with a pipe thatis totaly loose and can not be taken out of the head.
It looks like it has been flared from inside together with a washer. My problem is how to replace it or repair it. Looking at the photos of similar heads there is no acces to the pipe form inside of the head. The nut at the front will not budge but even if I am able to remove it, how would I take the pipe out if it's flared form inside.
Would anyone have any idea how it was fitted at the first place and is there is any chance of fixing that pipe without removal of the head.
Ahy help would be greatley appriciated
Cheers
Zac

I have never taken this pipe out on either of my engines, but my hunches are these:

-The hole around the pipe is threaded
-The nut is to lock the pipe in position in a certain angle once it is screwed in the head
-The pipe is flared, but before it was installed
-There is still a piece of plastic? inside the threaded hole that stops it from coming out

Douse the insert in a good penetrant oil, and tap it around a bit.
There might be some scale around the pipe, stopping it from coming out.

Bit late now, but there is a steel bush missing in the head that the pipe nut screws into . These are normally never touched because they are stuck in place with corrosion and getting them out will wreck the head ,necessitating expensive welding repairs.
