996 eplacement engine question .....

[Sir Snaz]

HI all ......just been looking at new weekend toys ....and the 996 keeps popping up over and over again.

I have, obviously, read all the stories re IMS RMS yadda yadda yadda ....

I just wanted to ask the Porsche collective ......if I find, say, a 2002, manual with 60k odd miles on the clock, that's had its engine changed under warrantee at an OPC at about 45k miles (and in 2008) ....what is the likelihood of this replacement engine having problems? ....ie are the replacement engines Porsche provided free of said IMS/RMS worries?

cheers in advance
