Note much rarer failures to BKC .
As some of you know and have been victim of the conrod thrower 1.9 tdi 105 bhp .

It is modern bi-metal bearings , long oil change intervals , owners thrashing the daylights out of them and brittle sintered powered forged metal GKN type con rods all added together that cause it .
The upper bearings wear through , pick up on the crank , micro weld , stall the rod and then pop out for a visit , often through the AC compressor !
Change the oil every 10K and change the rod bearings at 100K and they will just keep going .
These all came out of the same engine , on the left are the standard lower shells and on the right the Sputter coated heavy duty uppers !

Get them upper bearing shells changed folks , personally I wouldn't even wait till 100 k , obviously do the lower as well whilst at it .
