Hope someone can help me on this am i right in thinking the original coolers were not stainless hence the problems and the new ones are stainless. If so would the stainless one be expected to last forever. Reason i'm asking is i think mine has been replaced already and if the stainless ones dont fail then it saves me a job, if they do still fail then im just going to change it whilst i've got it stripped down.

Well stainless will still rust but will take an awful lot longer of course...
And yes the problem with the original ones was rust causing holes and hence leaking...

I think you'll still have problems if coolant changes haven't been regular enough. You've got a stainless cooler, cast ali cooler plate and a cast iron engine block all in contact so the corrosion inhibitors need to be top notch. Most likely outcome is that the cover plate corrodes away, IMHO.
It's not an "end of the world" job though so I don't think I'd replace one as a matter of course unless there were signs of failure of it was out anyway and looking rough.

Thats the problem i'm having as it looks like its had the oil cooler fail(coolant is brown ish)in the past and at the moment i dont think theres any antifreeze in the system. Iv'e allready brought the cooler kit as i want this engine 100% so i might as well just change it whilst its apart. I'm also doing the thermostat ,transfer pipe cam cover gaskets expansion tank hbv etc at the same time and cam belt kit and water pump next month so hopefully i wont have any other problems with it.
