200tdi possible turbo problem

Hi all,
my 200tdi likes to have a good smoke when the revs get too high in any gear, also when in too higher a gear for the speed.
Been told this could be a possible turbo problem, and it does seem to lack some power.

The smoke can be a mixture of white and black.
any thoughts?
thanks

Pump might have been tweaked, timing might be out, injector fault.
You can check turbo boost using a boost gauge.

First check the crank damper pulley bolt is tight, not unknown for 200s to come loose causing all sorts of running issues.

People always blame the turbo they do go wrong but not very often.

if my memory is correct there is a banjo bolt in the rear of the fuel pump that has gauze type filter .... maybe worth checking as when this blocks up it can play all kinds of havoc on your fuelling strategy

There is a gauze but the main feature in that banjo bolt is the small hole which causes a restriction in the to the fuel escaping back to the tank so the internal fuel pressure is always around 70psi.

Lynall is that 70psi created by the fuel pump or the injection pump as 70psi seems high for fuel pump?

so its ok to have a restriction before the restriction ? or maybe that crank pulley is loose aye

how sure are you this time its not a turbo ?

Created by the injection pump itself as it has its own internal rotary vane pump, quite a few other makes of car run the bosch ve pump and dont have the engine mounted pump that land rovers have.

If you try and find some guff on the ve pump theres some good reading to be had, bloke from the series 2 forum told me you can adjust the pressure and apparently many many cars are running to low a pressure as std I think this is why some cars repsond to tuning better than others.

He was/is a proper wizz and built pumps from bits of land rover and transits to get what he wanted, way out of my league.

I cant be sure as I like everyone else am diagnosing remotely.

How sure are you it is the turbo?

Turbos do go wrong as Im sure you know, but the different smoke colours points to a fuel/air problem of some description.

The 200tdi is a tough old bird as is the turbo. its getting old now but is still a good powerplant

thanks everyone, im going to have a good look over the engine and see if i can see anything that looks obvious, will let you know i find

Head gasket

thats a very good idea and good choice running some more tests ...and further diagnosing before changing the turbo and head gasket

are you serious
someone tweaked there fuel pump with out any preassure or live data readings or dyno testing nor EGTs and boost pressures
are you suggesting he turned a few things up then just winged it from the exhaust smoke?or using a flow meter
since you have done some reading your the guru .... please explain in more detail as many cars will be different due to age wear an tare specially when the use of bio fuel in some areas

What I dont get is why you ask questions about things that havent been mentioned
Pump tweaking
Live data
Dyno testing
Egts
Boost
Tuning
Winging it
Flow meter
Guru
Bio fuel

All not mentioned by anyone else but you?

The internet is quite simple, if you dont like what someone says either.
Reply and get all arsey and look a fool
Or just dont read or reply to their posts thus not looking a fool
It really is that simple

Ps do you own a 200?

the only advise from your self is to check the damper pulley .no i do not have a 200 tdi but i did own one a few year ago.unfortuanatly the timing belt let go... ps i never knew it was agaisnt the rules to comment on a topic if you dont have the same vehicle or engine

I did not mention any advice in my post you quoted.

The reason I asked whether you owned a 200 was to see if you were just a bar stool mechanic and the fact your cambelt failed kind of says it all.

its unlikely the turbo they pass a lot of oil when they fail,try it with air intake hose to turbo disconnected

LOL i like your sense of humour

..unfortunatly the car was purchased 2nd hand bought as seen at a cheap cost when the cam shaft pulley came loose the teeth on the vac pump and camshaft where also destroyed allong with rocker gear and push rods... unfortuantly i was milli seconds to late to turn engine off i was more concentrating on getting home my bar stool LOL

this is why i was more focusing on the fuel injection system in this thread as my 200 had fuel injection issues prior to the timing issues.... my injectors where weak as i had them tested i also found that my bango filter was clogged as you should agree there should be no restriction before the restriction

the engine its self might be bullet proof and a good work horse providing the things bolted to engine are working correctly like injectors fuel pumps and to have these to fail can be costly to replace or repair .... lucky for me my fuel injection guy who we use allot through work while i sit on my bar stool tested my injectors for free... he could not repair them and suggested a brand new set of injectors will be needed ...this can some times work out more than you purchased the vehicle
