hi i am currently refurbing a defender 90 300tdi (you name it its needed it it). stupidly not reading the horror stories about the britpart rear crank oil seal i have recently fitted one. my question is has anybody fitted one of these seal and it has turned out a success. i have not yet finished the project and predict im around 2 weeks from when i will be firing the old girl back up and my biggest concern at the mo is this seal. many thanks in advance mark
