Hi guys, hope you can shed a light on this for me. Put this on Ford Transit Forum already but have had no interest in it yet.

Details - 2014 Mk8 Euro 5 Transit 2.2tdci FWD 310 Trend.

Ok school boy error on this one first of all... sorry up front about that.

So noticed my van was dropping a bit of oil before Christmas 21 (my mot is due 20th Jan 22 BTW). I only do 30 miles a day in my van 5 days a week so low mileage and I dont thrash it. Was checking the oil regular to keep an eye on it and figured I would get the guys to have a look at it in Jan at my mot as that wasn't that long to wait also keeping and eye on it making sure the oil is topped off if needed as it was not that serious then. I bought the van Jan 21. The first thing I did was put new mot on it and did an oil service, I always do that with my new vehicles, you just dont know with second hand.

Anyway the oil seemed fine up until new year then I noticed it started to drop only slightly more at first maybe 50ml a day, but steadily increasing over the next couple of weeks anyway kept checking the dip every time I travelled, sometimes it needed a bit, sometimes not. Did not drive the van for 9 days over Christmas / New Year. Back to work on 3rd Jan.
So the 20th came and it was in for the mot which it passed no problems. The guy said it nearly failed due to the oil leak so it was borderline pass. I said yes I know I need you to look at that for me and arranged for me to bring it back in a week to get looked at, I thought fine fair enough hes just passed it with minor oil leak it should be ok for the week till then. So thats what I did remembering to top it off with oil if it needed it.
So during that week I noticed it started to smoke a bit after it was warmed up for about 2 minutes and then cleared, all this time it was running perfect no problems apart from the occasional smoke and the bit of a oil leak, thought to be honest it may have been some oil dripping onto exhaust and burning off once to temp. Then one day a lot of smoke after 1 mile driving, I stopped straight away turned off and could see the smoke was coming from the exhaust IE engine, it was white with a very slight blue tinge to it but mostly white though and a funny burning smell but not like deisel, more like rubber plastic. This was not steam I had been checking the coolant every time I did the oil check (no coolant loss, no pressure build up, no mayo deposits in res or oil cap so Im guessing we can rule that out for now) temp gauge always bang in middle and slowly creeps up to temp from start.
I waited for the smoke to subside and checked the oil, it was a bit low just below half way, so called my dad to bring some oil on his way back from work to top it off which he did. I topped it off and started the van - No smoke, no running problems at all. I got my dad to follow me back to my work place a mile away to drop the van off and give me a lift back home as I wasn't risking driving it anymore until I knew what was happening with it.

So now Im vanless...

Next day I had a closer look at the van at work and trace the oil leak to the rocker cover... and I know straight away its the dreaded injector seals as there is oil pissing out of number 1 and number 3... but I also know it can be worse than this and need to investigate further... I decided its NOT going to the garage as I will get charged a fortune for doing an investigation first of all and then having them quote what ever they wanted on top of that to fix it knowing full well the van could not be moved after the engine was apart at the garage... So I decided to have a go at the job myself, Ive got some experience IE bmw head gasket replacement and skim I know thats petrol and this is deisel but I felt I could do it if I put my mind to it and took my time (also I have use of another van in meantime lucky b*stard)... and here I am now not so lucky lol...
And now the story unravels... and all my school boy errors become apparent... I know I know... and this is where I need your assistance if you would be so kind. First I removed the the injector's, all carboned up as expected but number 3 had oil on it all the way to the tip I meen it was wet hey!!! copper seals on 2 and 4 ok but needed replacing as there was some ware, 1 and 3 completely blacked and leaking, replaced all with genuine ford kit including new seal bolts (binned old ones). Injectors cleaned and seats cut and fresh copper seals and new rocker cover / gasket (overkill I know with cover but there you go).
Last but not least the OIL mystery, so I dumped the oil... Hmmm thats a lot of oil!... About 8L in fact... sh*t the dip stick was not reading right, clogged up maybe? dont know but its reading right now... Bloody hell what damage do you recon Ive done putting in too much oil then? Be kind...

Current status - Running and ticking over great I think anyway - BUT still have the smoke once at temp and pushed over 2500 rpm... think it may be turbo as its clean until its revved past 2000rpm, because I can start it for 20-30 minutes drive about at 1500-2000rpm no smoke but as soon as its up to heat and the turbo is used I get the smoke, it seems to subside after being left in idle but dont know as did not want to risk it any longer if further damage is done leaving it running.
Could it be the turbo dumping oil into the exhaust somehow and this getting burnt off? Any ideas?

Any help would be appreciated.

Thanks in advance guys biggrin

From what you say, you have possibly been lucky in one respect, as in it sounds like you have got 2/3 of the issues sorted.

Unfortunately, it also sounds like your thoughts on the turbo could be right.

The turbo is basically always spinning when the engine is running, so forget about "when I use the turbo" as you are always using it, it just isn't helping much until it gets up to speed fully.

The white smoke is likely the turbo burning up the oil due to seal wear/leakage internally, which is why you only see it when the turbo gets right up to speed.

Thanks for the reply my man much appreciated below are extra video from today let me know what you think? Do you just think it maybe oil in the turbo inlet/outlet which needs cleaning after the oil error?

Reckon the crankcase vent system might have got clogged with oil residue to the overfilling?
Once crankcase pressure increases under load it might be enough to push oil past the turbo seal maybe?
Have you checked the turbo hoses and such for signs of oil buildup?

If you force the exhaust to heat up not long after starting, does it spew smoke quicker than it would otherwise?
Just wondering if you’ve got an exhaust system full of unburnt diesel.

Hi Demelitia,

Thanks for the responce the videos I tried to upload to Youtube did not complete so please try the above links again these are NEW LINKS now for reference to your Question/Answer! I talk about that in the videos. Anyway in short my next step was to start taking off the turbo and checking inlet/outlet. I know the cam cover outlet filter can get blocked due to this problem IE seals going but I replaced the cam cover complete so that filter is brand new so should be no chocking up there I will check the further pipework to the turbo and beyond for traces of oil. Ive seen a similar thing on a deisel Hilux fitted with a CCV Catch Can Venting system which pressurised and blew the seals both sides of its turbo... so we will see what that reveals... Thanks for your interest guys very helpful
