Hi all
My Gu has suffered an engine failure, at this point in time the symptoms seem to indicate its blown a couple of pistons due to turbo overboost. The engine was stock standard, I had intended to fit a Dawes Valve but time ran out. I can't really complain as the truck is 10yrs old and done 340k+, up until this incident has done everything asked of it .

Is it possible to do an engine rebuild whilst the engine is still in the vehicle or does it have to be removed?

Mike

The faillure of pistons is not due to overboost. MAF failure or a build up of EGR gunk in the manifold.

I believe it is possible to rebuild whilst in vechile, but to remove the sump you need to remove the gearbox, so its only the engine mounts to undo to remove the engine.

Actually not necessarily correct either.

The failure of the pistons is most likely because "that's what they do........"

Still, this one had a pretty good run at it.

what Ferret said... Not enough room to work in the engine bay... and you will need to machine cranks ect...
Just finished doing my rebuild and motor back in now. Watch out for the 2 top bolts on the bell housing they are a F$%in pain in the ass.

3L failure - maybe a couple of pistons ......

Hi, sad to hear of the failure --- curiousity question,, at any time did you have any glow plugs fail?. If so did any of the glow plugs have missing sections of the ceramic tip?..

I look forward to your reply - again sorry 'bout the 3L... Cheers Q8160
