Engine died where to start.

[shortymk6]

So after my exploding diff Las week . I got it all rebuilt and has bee driving lovely. Today driving along a 3000 rpm and I feel a knock from the engine which just dies. The van will turn over really fast but will not start. What should look at first??
Van 115 350 red 2.4 tddi

A good start is getting it plugged in and see what the codes say, could be anything from crank sensor to fuel pump.

Have you looked in the engine bay for oil and debris to rule out if it's put a leg out of bed

ok so took rocker cover off and all rockers are loose meaning not under tension. i can turn engin by hand . does this mean chain has snapped?

[Airthies]

Sounds likely, if engines turning over but camshafts aren't turning then something's gone, more than likely the chain, if the cams are still turning then it's probably jumped timing and smashes things up.btime to pull front cover and head to see extent of damage.

Ok front cover off and chain has snapped.
Do I need to remove the gears to get the chain off and on

Broken chain would probably mean rocker ladder is most likely broken and/or the bolts have been pulled..

The ladder wont be broken but the head may be scrap ,its a mk 6

I found last time when it jumped a tooth and the chain stayed in tacked it did smash the ladder. This time I'm hoping the chain snapped and the valves went up out the way as they where no longer being driven down. Fingers crossed

There will always be at least two cylinders with either inlet or exhaust valves open at any one time, no matter at what point the chain snapped.

i was going to put new chain on and see what happens. would you strip it right down or just retime and see if it runs?

I would have thought you would have had enough experience by now Put a genuine chain kit on it this time After you checked the cam carrier viewtopic.php?f=5&t=169610&c=1

Yep smashed carrier. I have had it happen before twice. Same van. I think the chain snapped because of the diff exploding last week. It must have stressed the chain.

They are failing because you are using skite parts nothing to do with the diff http://dohertytransitparts-com.3dcartst ... _5691.html There are two types and as your engine has been changed give them the part numbers of the cam sprockets
