New Or Not New Freelander Engine?

Hi , I hope some one can advise.
We foolishly bought a Freelander 1.8i 18 months agoo on a 2000 reg. FROM THE MAIN DEALER.
Yep you guessed the head gaskets gone at just 37K miles.
The loal dealer has had in workshops for 2 week and all conversations were that it needed a new engine at a charge of £3000+
This we agreed to untill Thursday this week when I called the dealer to ask where I could get a POST WARRENTY CLAIM FORM from so that I could claim the cost back. The guy was very helpfull and offered to do that.
Good news they came back qand said they would settle the cost at 100% we don,t need to pay , apart from £300 towards labour fantastic news....I asked the mechanic the following three questions
1, will it be a new engine.......YES
2, Is it a different type as the original was prone to this problem.....YES
3, Are the chances of this happing to the new engine less...... YES.

Oh we were happy bunnies such kind peeps those main dealers!

We collected the car today
Does it have a new engine.....NO! but everything inside the carcus is new!

Not quite what we believed to be the solution or what had been expalined to us.
Does anyone know if this is the correct form of action or are my suspicians right and that once it became a post warrenty claim they decided not to put a new engine in..By the way the car was due to be collected on the day i Questioned about the warranty,,,then suddenly it would not be ready until today Monday.
I hope I am very wrong ....help?

hi you will find that all the engines are sent back and are reconditioned they call this new,brand brand new engines are in short supply,you should have had a conversion on the cooling pipes done which moves the thermostat to the front of the engine looks white in color on the right hand side,dont worry about a new engine i fitted a new one and it blew up after 8 miles,you can get the head skimmed and put a spacer gasket in there paynes do a gasket kit for the 1.8 freelander,the gaskets are the weekest link stainless steel and rubber,these are usless they wont have stiffed you on the engine everyone gets the same.it is the same engine and it possible will suffer the same headgasket problem later on who can tell the modified coolant hoses do help a lot make sure its been done.
