help!!! 2.5 TD head?

[100ps_drw_hicube]

someone please help i rushed into changing head gasket and head at the weekend put all back together runs but tonnes of blue smoke and no power anyone any ideas???? also turbo is screaming but appears to be getting oil

oh when it idles its more a greyish smoke when you cane it up the road its blue no water in the oil either

[transitgeoff]

sounds like the turbos dead

[100ps_drw_hicube]

ok i will try another on it tommorow thanks horrible job to do though takes ages to get all the crap off that surronds it never mind gotta be done

[100ps_drw_hicube]

still no luck swapped with a turbo i know works still no power still tonnes of blue/grey smoke not as much grey smoke since i bled the injectors any ideas or leave to a garage

What made you change the headgasket in the first place

[100ps_drw_hicube]

the main reason was the head was cracked at the back the exhaust manifold was cracked and the valve seals had gone + there was slight trace of water in oil


since i have changed it it dont idle very high sort of hunting?

[Luke]

You swapped the head then where did you get the replacement head from
If you are getting blue smoke there may be oil getting into the combustion chamber - do you have any way of doing a compression test
im just thinking things related to the job you have done was the turbo totally ok before you started

[100ps_drw_hicube]

yes i swapped the head with a brand new one i got it from a guy who used to run a fleet of mk5 td's and changed to mk6's so i know its the right one! unfortunately no way of doing a compression test just had a look now with a torch there seems to be a small amount of oil getting into the throttle housing?from the turbo and up into intake manifold

[MrMPuk]

Sounds like the turbo to me, must just be coincidence that it went when you changed the head.

[Luke]

just a thought and this needs confiming by someone who knows
can you run it without the turbo on (fit a normal exhaust manifold) - just to test it - would that tell you anything

you didnt drop the turbo when you took it off did you?

[100ps_drw_hicube]

no i didnt drop the turbo it might be possible to run a normal exhaust to test it bu t there is 2 holes that will need blocking up, the oil feed from sump to turbo and the return pipe to the block also ther are a couple of rubber pipes that go to wastegate etc ? dont know what to do with them?

[100ps_drw_hicube]

hardly any blue smoke now just loads of grey also there is a weird noise coming from the lift pump could this be knackered?? also i drove it for 60 miles yesterday the power gradually increased but not to what it was it is still idling very rough! it is only idling at about 600rpm it should be about 900rpm

[webby cue]

it could be running weak. pump timing out a tad when you put the belt back on. whiteish smoke usualy a sign of running weak.

is it using oil or water up, more than normal.

[100ps_drw_hicube]

i didnt have the belt off i am not brave enough yet to touch timing!!! it doesnt seem to use any oil or water tho when it took it out the other day for a long drive the temp guage only just moved into the norm usually it goes to norm after about 5 miles there doesnt seem to be any white smoke just a tad of blue and loads of grey

[100ps_drw_hicube]

had someone look at it today no 1 cyl is not firing tried different injectors still no luck someone else suggested to check the valve clearances will try that in the morning and see what happens also anyone know what the head is meant to be torqued to haynes manual says 52lbft but it doesnt seem enough to me anyone know any different???
