    2009 2.0 CDTI Seized now freed and running... was it even seized???

    Forum Key Rings
    Hi all,

    I'm looking for advice, or anyone who might be able to shed light on my insignia (suspected) engine issues.... so, over a month ago now, my 2009 insignia CDTI died at around 60mph, no warning lights, or odd engine noises etc... no warning what so ever, I was accelerating at the time. I pulled over, and it would not turn over. RAC came out, tested battery, fine... attached starter pack, still would not turn over, tried to turn engine on breaker bar, and informed me that the engine had seized!

    next day, I attached a breaker bar and tried to turn the engine, it turned, but was very tight. I removed the glow plugs, and sprayed a high performance lubricating oil for seized parts into the cylinders... left overnight, and tried turning again... still tight. left for a number of weeks... bought another car, advertised on Ebay as non runner...

    a number of weeks later, car still not sold, I decided to take the drive belt off and check the engine again.... it was still tight, but possibly a little easier to turn... put drive belt back on, decided that the drive belt being removed did not make any difference, but perhaps the lubricating oil had loosened the engine a bit.

    Charged battery

    Tonight, I tried starting the engine again on the starter motor.... it turned... very slowly... persisted, it turned better.... kept going and eventually the engine fired, and died.... tried again, eventually it started ran for a few seconds and died... kept at it, it ran, but would die if I pressed the accelerator. when it was running though, it sounded ok. left it for a bit, tried again, left it running a number of minutes, then turned off.... now it starts fine, revs fine, drives fine, and sounds normal... although i don't dare run it longer than 5 mins..... no warning lights.

    during the whole process, the only odd signs in the engine bay was a slight electrical smell, and possibly a wisp of smoke towards the back of the engine when i was first trying to start it... but I put this down to the work I was putting on the starter motor.... other than that, no odd noises from the engine, no oil leaks....

    what happened? and what do i do next?

    I am thinking I need to drain the oil, perhaps flush the engine with some kind of engine flush although I have read mixed opinions on using engine flush... any thoughts on this?

    Are there any signs i should be looking/listening for, it sounds ok to me, but i'm no mechanic

    If i take it to a garage, how are they possibly going to diagnose this without stripping the engine?

    Has anyone else had similar issues? i have read a number of posts about oil flow issues with this engine, but surely if there was a blockage I would have had a low oil pressure warning light?

    ...Happy the car is running again, but would really appreciate some advise on what I should do next?

    the oil seal between the pump and pick up pipe fails on these engine,usually on the older higher mileage cars,resulting in bottom end failure/seizure. but if yours is running again with no noises ,don't know what to suggest tbh

    I would get the timing checked as the belt may have jumped a tooth or 2??? Get a code reader (OPCOM or similar) on it to see if anything is stored

    Thanks for the responses.... If the timing belt had jumped, would it not be running really rough? i.e out of time? or not run at all? now its running, the engine sounds fine.

    I am planning to do an engine flush to clean out any gunk that might be causing blockages, and to replace the oil, so I know that it is the correct grade... and see to what comes out, then fill with new oil, and try running the car for a bit to see how it runs...

    Also the lack of warning lights is still baffling me... is it possible that a warning light can be bypassed? Reading into the issues with these engines, and speaking to a couple of garages, they all say the issues start with an intermittent oil pressure warning light.... I have never had the red oil light flash up, i'm pretty sure it illuminates when you put the key in the ignition.. as it should do (i will double check tonight)

    It sounds very strange. To be diagnosed as seized to then kick back to life again without any new parts? I've heard of a Corsa doing the same thing a while back though. It turned out that the oil had gone that think that none of the engine would turn. Draining it and changing the timing fixed it.

    I would get this to a mechanic or even one you call out to once over the engine. I would advised against using any engine flush treatment. Only heard bad things about them. Drain the oil and put new oil in it. Check the timing of the engine and timing belt see if that's the issue.

    Keep us updated please.

    Thanks for the reply, It did seem odd, but from the beginning, once I got the car home, i found that the engine was very tight, hence the starter motor could not turn it, but it would turn with some force.... I was only going off what the RAC man told me by the side of the road. it definitely loosened off over a period time & after spraying high performance penetrating oil in the cylinders. Getting it started, it felt like it was sticking, but gradually worked its way free... almost like there was a point in its
    cycle that it was getting stuck, but with each turn of the engine it stuck less, until it ran..... i'm not a mechanic, but having talked to a few people, it makes sense to me that perhaps oil flow had been restricted or blocked to some part of the engine, and that part has overheated causing the seize... but perhaps it was only one cylinder that seized.... I have read a number of posts about these engines being prone to oil blockages (Oil levels were fine on the dipstick, plus no warning lights). This was why i was thinking engine flush to try and get any gunk out that could potentially cause the same issue... but I must admit that i have been in two minds about it having read mixed reviews on engine flush!

    I still haven't done anything yet, I will definitely do the oil change.... I'll have a think about the flush (i really want to do it, as I've convinced myself there must be a blockage), I have a good local garage less than a mile away , so I may drive it to them to check the timing belt.... is this something they can check easily? or is it a case of they may as well change it at the same time? what are they looking for? is it something I can visually inspect myself? the timing belt was changed less that 10k miles ago

    I am reluctant to spend too much on this car, as I had resigned myself to selling it as a non-runner, and even though it is now running, and sounds ok to me, it may have still done serious damage to the engine that is not really economical to fix.... but it is definitely worth investigating further.... half of me thinks sell it now as running, but in need of attention, explaining fully what has happened to it, and let someone else who has more time/knowledge/connections deal with it.... or I follow the steps above hoping it fixes the issue, then run the car for a good length of time so I know the issue has gone away, and the engine is hopefully fine, and then probably trade it in 6 months time..... I know that if it seizes again, it is worth next to nothing, as I had been trying to sell it for a number of weeks before I got it running again.

    I will keep you posted... I have a few days off, so I may do the oil change this weekend
