Hi.

Friend of mine has one of these on '57 plate at 75k. He says he gets blue smoke on cold engine start, e.g. in the morning.

He thinks it might be oil in the turbo but I think it's valve seals. He says it doesn't use any oil and it only started after it was overfilled by a garage (he dropped the oil and refilled it himself). He put 5-40 in it.

Any ideas?

Thanks,

D

Hi Jerzy

The Correct oil for that engine/car is 5-30 fully synthetic

How many miles has your friend covered since the car was overfilled.

I would change the oil to the correct spec with a new filter

Also when was the fuel filter changed, Ford say 37500 miles, i and many of the other people on this board say 10,000 miles as its ony a fancy piece of filter paper in a canister

Hope this helps

Hi Jerzy

I know what your trying to say about oil not being that important. but tbh if we put blood in you that does not match your original blood your body will start to shut down

not sure id be comfortable selling on a car that works but is potentially going to cause a lot of problems, id rank that up there with removing the EML light to fix a problem.

unless his trading it in to a dealer, since most of them a thieving so and so's id have less of a problem doing that ;) but still, some poor sod might end up with that mess and all the bills to do with it, I would be raging if someone did that to me.

Smoking first start up is a sign of leaking fuel injector as cylinder fills up over night.

If it's chucking out smoke I recommend blanking the egr value to prevent recirculation.

EGR is best blanked anyway regardless of smoke or not.

more discussion on that here:

Cheap diesel;

After changing its eh pigmentation can contain trace of sulphuric acid which will harden rubber over a period of time causing deterioration of seals; possible contributer 馃槙

Also an individual may choose a higher density oil in the event the engine begins to consume alot of the current grade.

that maybe so, but knowing what you know about the DV6TED4 engine, I'm not sure id want to make it any thicker than it already is! :)

Totally agree mate,

It's not somthing I would personally do on a modern turbo diesel.

Well....all of them, for the mk2 era anyway!

there are some variations of the DV6TED4 engine, some minor changes but its essentially the same beast,

the variant C model seems to have sorted out much of the problems
