Broken down won't started suspected timing chain

[marc1234567]

2002 mk6 . 2.4 diesel , mechanic is saying based on the diagnostics probably is slipped timing chain and is saying the job is about 9 hours. Can anyone confirm that is about right for the hours?

Is there anything else it could be? the errors were from memory powertrain control unit , 2 faults , one was fuel injection error and other was an expected engine stop . the crank shaft sensor has been changed. easy start failed to do anything.

I can't offer you much help other than I think the job is around 4 - 5 hours, possibly less if you do them day in day out with the foreman/manager aiming a loaded gun at you

Not if the head is kaput which is more than likely

it it doesn't run on sniff you have head trouble most likely done the cam shaft cradle

I was easing him in, yes, no starting on heroin is a trifle worrying.

Is that head off or in situ repair guys
I suspect if valves have clattered then it an OFF.

they don't bend valves they just push the cams up resulting in cradle breaking or striping the camsaft follower bolts

but either way depending on the damage it has done to the above it can be repaired in situ but if the cam cradle is broken then its head of and another one

Nasty, so the follower bolts must be pretty soft, can you helicoil them then

yes unless it looks like this

So that's the carrier, needs welding by the look of it

It must bolt to the head, it's those threads I'm talking about, did you say the bolt strips or do the threads in head strip out?

the broken bits is were the cam follower bolt to so you car'nt repair new head as the are machine together when manufactured

[marc1234567]

Oh dear. I was thinking that if chain slips it doesn't start due to incorrect timing but not necessarily damage but looks like that likely is not the case

So is it the case that generally the head is ok and cam cradle is broken and to be replaced?

If it has pulled the bolts "and broken" the cradle/ladder....it will need a new/second hand head assy, they are a matched pair and machined as one piece....sometimes people have tried to replace the just ladder and it locks the cams solid. You can't buy them separately from Ford as they're a matched set.

the timing chain has broken and the rocker cover has been removed and no cradle damage is observable.

the mechanic is not sure and asked me to ask here.

the camshafts can be turned and the mechanic says that could be a bad or good thing. he is unsure as to whether the valves may be bent or whatever.

is there any way there may be no damage to valves etc.

Strange for the chain to actually break..?? If so it will be as Karl mentioned, it's unlikely to bend valves as they're straight on to the pistons and quite robust.... they usually pull the rocker shaft bolts or break the rocker ladder...or both.

If "both cams" can be turned 360 degrees with cyl #1 at TDC and without turning the crank...there's problems, valves should be touching #1 & #4 pistons.
