I bought a Britpart 300 Tdi rear crank seal, pulled the engine out, fitted the seal, replaced the engine and the bloody thing leaked worse than the one I had taken out !!
The next morning (the day of a forum trip to Wales) and after my night shift, I had to pull the engine out again and fit a genuine one that Stu had managed to find whilst roaming around in his AA van
Over the last couple of years I've come to the conclusion that Britpart are even more carp than the old "county" brand carp. At least County never pretended they made good bits
