Thanks for that Rover's north link, they have nice exploded diagrams. The part that is damaged is this one:

PIPE ASSY STEERING BOX DISCOVERY II LHD, RND901, QEP105400 - Rovers North - Classic Land Rover Parts

 

Rovers North has one of the best sites for finding parts. That part is way cheaper so it's better it turned out to be that one.

 

yes; it can be replaced new or used but keeping with your goal of not spending anything until you know if the engine is any good, i would put a $3 union on it.

 

I pulled my fan out to replace my radiator and look what I found. Knowing now what could happen I felt compelled to order a new fan.

 

Nice save!!
This is the exact reason why I suggested buying a new fan and not risking another failure. Even though that used fan looks good (because they clean it up with soap and water) doesn't mean it is.

 

don't forget the check the w/p bearing and motor mounts, something made that come apart.
in days of old it was common for a broken mount to allow the engine to jump up causing the fan to hit the shroud, but back then things were made of metal. you got a bunch of noise , you didn't grenade the whole front of your engine.

 

and just to add to that...when jacking up the engine to check the mounts, be very careful and take it very slow checking the mounts regularly as you go up. You only need just enough lift to see if they are cracked (top and bottom no longer one piece held together by the rubber).
Too much jacking and you could break a motor mount that is not already broken.... as well as other stuff. Not enough, and you won't be able to tell if either is broken. There is a fine line between not enough and too much... so slow and careful is the key.

and w/p bearing to be checked for play with belt removed.

 

How did you take the radiator out? RAVE has an incredibly complicated method of removing the front grill, horns and all sorts of other stuff, while a google search shows a bunch of threads that talk about getting to screws from the side if you remove the airbox and battery and that it takes 30 minutes that way.

Unfortunately there are no pictures of the second method, so I'm wondering what you did.

Thanks!

 

so you do NOT loosen the nuts at the bottom of the motor mounts before jacking to check?

 

That would be the ideal way to do it.
