Vectra dti crank breakage
24. Mar 2011 at 23:33

A mate of mine bought a vectra 2003 2.0 dti (y20dth) cheaply with a broken crankshaft,he has sourced a second hand engine and fitted it and at first all seemed ok,he rang me tonight to say that this engines crank has bust as well,is he just unlucky or is there a problem with these engines.He used the original fuel pump and dual mass flywheel,any connection ???
thanks

Not a known issue.

I guess the question is, has the crank really broken.....

dual mass was checked when second motor fitted and all seemed well,gearbox was free and car was driving nicely,was travelling at 30 mph in fourth gear when second failure occured

Well, hes doing something wrong somewhere as:

'rare event' x 'rare event' = 'lightning strike probability'

which is equal to

'another fault causing the issue' Thumbs Up!

Mar 2011 at 16:31 my gues would be the dmf, it must be out if balance at certain rpm which you could not check for with visual inspection? actually thinking about it do these have a two piece crank pulley? i.e harmonic balancer on the front of the engine
