1.6 Tdci Mk 6 Turbo Tell Me

[frund]

I have a 1.6 tdci 38k 08 last of the batch sort of thing. I have been reading about the Turbo problems with the the Focus 1.6 tdci. (same engine I think) Turbo pops due to poor oil supply, engine full of carbon? impossible to clean out, new engine needed? Injector seals may be the cause?

Anyone know what or why this happens and the percentage of engines that give trouble or mileage when prob occurs. :(

as far as im aware the turbo pops due to the lack of oil supply(stated) but it has its own feed from the sump which does get clogged with carbon yes due to alot of round town driving, you could always take of the turbo and clean all manifold out, so it can beathe easier

Just as long as regular oil changes/filters are done say every 5k then this is unlikely to happen, also drive it kinda hard so the carbon heats up more and leaves less soot.

Also always let car run for few miniutes before u start drivin and same before u switch off engine

Interesting indeed.

Having read quite a bit on this subject. It would appear that vigilance is required. It may be down to turbo pipes getting too hot due to exhaust proximity and the oil baking or changing in substance. Has this been changed in later models 6.5 onward? Partially Blocked EGR causing poor breathing amongst other things. Some folk have fitted blanking plate to EGR up to mk6 but not sure on the Mk 6.5 onward may be electrics involved and impossible unless EGR can be electrically disabled. Injector leaking into oil needs new injector copper washers.

. Checking the oil filter should give a indication of sludge/carbon build up. Removal of top cover to inspect injectors and replacement of copper seals. Interesting as the seats may be carbonised so some form of cleaning and gathering of particles must be employed even reseating using a proper tool. Checking return oil from Turbo 300 ml per min using a locally manafactured pipe. This would also show the quality of the oil. The sump is impossible to drain Properly due to the plug housing being concave so there is a danger of sediment remaining and clean oil going on top of this. One writer removed the sump to check on things, there is a liquid gasket to replace apart from that looks possible.

Any additional comments welcome or any mistakes pointing out.
