Jak provést levnou a dobrou prevenci
Ale ojnice venku např. i u
Exact same thing happened to me on thursday on motorway at 75 m/h 50 miles from dover docks on 1500 miles trip across europe. Conrod made a big hole on BSW engine on Roomster 1.9 tdi, PD, 2008, 24 000 miles on clock. Oil changed previous day, level checked 4 times. What should i say.....? Will contact customer service after 2 weeks when return back to uk.
Taky jsem našel motor ATD s ojnicí venku atd. atd. atd.
Ještě tady je jeden názor
In my professional opinion, looking closely at your photos, it definitely looks as if the piston picked up on the bore and seized first. This could have been caused by the injector nozzle hosing fuel (if the needle was stuck open), causing the oil from the sides of the bore to be flused away and causing the piston to seize in the bore. Or it could have been due to some foreign matter getting into the bore - the only way to tell would be by looking inside the engine.
Once the piston had seized, the crankshaft turning motion would push the conn rod out through the block, snapping off the end of the conn rod - with the bits of conn rod/bearing/bearing cap either in the sump or cold-welded to other parts of the crankshaft!
All in all, the block is obviously completely written off and, if the crankshaft was affected by the bits of conn rod such as to cause the timing belt to break (quite likely), the valves would hit the pistons and the head would be a write off as well.
I'm glad the new engine seems to be working well. Don't let anyone put anything in the fuel system to "clean it up!" The clearances on the PD (unit injectors) are extremely small and sensitive to debris/wear and fuel additives can cause massive damage! VW in Peterborough told me that one of their customers had to have a complete new set of PDs at £3,000 when they used a fuel additive
