Hi all,
My 1.6 Td has been smoking ever since I bought it. This was eased by having most of the engine overhauled last summer. It still smoked s little when cold, accelerating, when doing say 60mph and going up hill after I had it back and was told the turbo was leaking and this was the cause. So I have been shoveling in Tesco own brand mineral oil and going easy when building up speed. This way I was going through maybe 2 litre's of oil a month and always ran it a little low.

Any way, today I was off to pick up a new bad which involved 30 motorway miles. I checked the oil and it was below minimum. So i purchased a litre of oil when I fueled up and dropped it in on the forecourt. After about 20 miles of smoking (cars hanging back or racing passed me as usual) and a short stint doing 70 on slight incline, I pulled off the motorway and while I was stopped at lights my truck was chucking the smoke out (thinking to myself something was badly wrong). Anyway had to carry on as although it was smoking it was driving and pulling lovely - so I drive around the round about and off up the A470 expecting to see clouds of smoke in my rear view mirrors but there was none, evan when accelerating up to 60 on an incline there was no sign of the clouds I normally leave behind me. Then on my way back and still bewildered at the lack of smoke there appeared one largish cloud of grey/blue/whitish smoke (that really worried me ) and then it went back to being smokeless evan doing 65.

Anyone have any ideas on this? I thought it may been the shell oil being a better quality oil than the usual stuff I put it but am not sure (maybe it's a little thicker and won't leak through the turbo so much?

have you checked there is no red diesel in there?

No red diesel what so ever Eddie, I can't remember the last time I bought diesel anywhere else but Shell

So you've got a Motor Holmes problem?

You've probably overfilled the oil & it's eventually chucked it out onto the hot manifold/exhaust resulting in muchas plenty smoke.

haha, wish I'd thought of that for the heading!

The last time is was full was last September, since then she's been running around on half at the most.

I checked the oil this morning and to my surprise very little oil had been used compared to normal. 60 miles of motorway driving normally slurps through a fair bit of oil. It's like the thing has just fixed itself (or somethings gone wrong that doesn't affect the running or pull of the truck) and has completely spun my head.

Cheers for the input though and any more is more than welcome https://club8090.co.uk/forum/posting.php ... =2&t=64037#" onclick="window.open(this.href);return false;

How many miles sense overhaul? Were rings replaced then? Maybe rings finally seated/sealed?

Hi,
Is the engine the original one or a replacement from a Golf etc.
Could it be that the dipstick is not correct for a T25.
I know from experience with a Golf fitted engine that the dipstick needs to be replaced with correct one otherwise you overfill with oil but think its all correct.
The give away would be a oil filler cap on the rocker cover, original van diesel engines did not have these.

Rings were replaced and I've probably done between 1500 - 2000 miles since. it's my daily drive so does get about town a bit Lloyd.

Is the original engine I believe Scoobydrew, no oil filler on rocker cover, just that filtery thing that feeds back down to the inlet manifold and intake.
