tddi argh! advice please (finished 26/3/10) Thank you FTF

[angeleye]

yes thru injector holes tester should have instructions, it will run as good as new im sure when you have finished, you will get a slight variation on compression between each cylinder,what the variation allowance is i cant remember on your engine, or what compression you should have ,sure winterheating ,or one of the techs will advise

[belly]

Dropped the tddi injectors off today to get reconned just got to get a nice bottle of red for my mate as for the cover i've already ordered one now so might aswell use it, old one was letting the front down anyway as i put new pulleys tensioner and belt as a matter of course on my transits

[belly]

Quick update, had a spare couple of hours this afty so got it built and timed back up to do the compression test! pots 12&3 all came in at 30bar is that ok? but pot 4 came in at nadda zilcho fook all oh well suppose i was expecting a bit much, starting earlier to get work done tommorrow so hopefully i will be able to get the head off in the afty i've already stripped most of it back down and got the cams out

[belly]

Finally got the head off today! all fairly straightforward and upon closer inspection in the daylight with the cams and carrier off it was as suggested by AK

My 54 plate tddi 115ps one managed to snap a valve spring and it sounded just like you have explained, could be wroth checking the valve springs

one of the inlet valve springs had snapped causing the valve to drop



Hmm that spring looks funny!



that will be why then



Dropped valve!



marked piston! doesn't appear to have any damage though!



Valve in question! appears straight and didn't stick at all



thank god it's a lwb
and i've had an idea



only joking

so what do you guys reckon?
1 should i replace all the valve springs?
2 should i replace the valve?
3 i'm also thinking of doing the valve stem seals also whilst it's off, is there anything else i should do whilst the heads off?
4 are the headbolts stretchbolts?
all advice and pointers welcomed cheers guys

the engine sitting for so long may have had something to do with spring breaking, why dont you just price up a full set of valve springs and valvestem oil seals.

whats the mark on the other inlet spring

i think you should be able to get 1 valve for about £20 for the sake of it, it will, and has by the looks of it been spinning round hitting piston so may have made the edges weaker still.

Thats what i thought tbh maybe the springs had gone brittle weak etc etc! that mark is a mixture of oil/bad light/i phone camera! i saw exactly the same thing and thought wtf is that! checked it and cleaned it off all and it's ok cheers winterheating think i'm just going to do the lot i've always tried to do things like that as its a false economy not to

[winterheating]

whats the rusty water marks from thats all over

[belly]

whats the rusty water marks from thats all over

Whereabouts? which pic?

[winterheating]

first pic all over bulkhead, and on side of cam carrier thats laid on your nice new ply floor.

[winterheating]

i think it would be worth checking piston protusion difference also for peace of mind before head goes back on.

Ok fair enough on the bulkhead but cam carrier hawkeye believe it or not thats clayish water from how it was treated How do i check that? and what you thinking? bent rod?

[belly]

oh and the nice floor i know a little cowboy eh should have covered it really ah well wood likes a good oiling

[winterheating]

yeah just to double check its not bent slightly, otherwise it would only make piston pickup and wreck the block.

[belly]

ok cheers i will swot up on how to do it and buy according equipment tools etc my locking/timing kit is ace as is my new compression tester although i did the compression test with the vac/waterpump not bolted back up and preceeded to replicate the exxon valdise

[coconut]

I'd pretty much garentee the piston protrosion will be fine with that minor amount of marking to the piston ( seen pistons with much worse damage when the timing has jumped and they have been fine )

Probably worth changing all the springs, depending on price of course

Replace all 10 x 17mm and 8 x 13mm head bolts, 10 rocker shaft bolts and put the same notch head gasket on as you've taken off
