Common problem I'm afraid , usually the crankshaft & con rods , however they usually get to 125,000/140,000 mile area before the dreaded oil light flashes up . We won't buy no more Insignia for the taxi fleet , we had 2 go like yours .

 

Hi Fred,

Thanks for coming back to me on this, sounds like the best thing then is to get repaired and get rid. Is this a common problem on all Vauxhalls or just the insignia engine?

When you had yours go did you replace anything else while the engine was out, gearbox for example?

 

Ours initially had a succession of wrong diagnosis , first off the knocking noise was thought to be the cam belt & tensioner then after that didn't cure it the DMF & clutch was renewed , noise got louder followed by the oil light coming on , must be oil pump said garage . A week later oil light came on when engine was given some revs , driver tried to get car back to garage by keeping the revs down but sadly one loud bang followed by dash lit up like a Xmas tree & deathly silence . Crankshaft , con rods , cylinder head etc etc . New engine fitted with original gearbox & recently fitted DMF & clutch put back on . Total cost was £2500 on original engine & £3500 on a replacement engine fitted , never again we said until 3 weeks later & our other Insignia went bang .

 

Is this across the range or just on the diesels it's a common problem?

 

2.0 cdti 160bhp diesels .

 

On my cdti Sri insignia low oil pressure only used to flash up in the winter on cold start up only never when driving. I managed to get 200k out of the engine with help from people on here.
Mine still drives but lack of power bit of smoke gonna look into head gasket. Still a lovely car I drove it first time again yestoday after it being at diesel specialist for few weeks.
My advice to anyone with engine knocking or excess smoke with no warning light get rid or its gonna be £££ from here onwards.

 

Thank jayus! Lol cheer's fred

 

Hi guys,

I bought Opel Insignia 2009 2.0CDTi, and i have now same problem. The "Low oil pressure - Stop engine" light comes every start when it is cold, but if i stop the engine right away and start again this doesn't come anymore.
This car has 313 000km in it's meter. Could this be just an cold starting problem that car isn't fast enough to check the pressure before giving me a warning? Or should i be worried now?

Car sounds normal and it can be normally driven?

I realise that this is a long while ago now, but did you sort the problem and if so what was it??
My 2012 Insignia does this and only on cold mornings!

 

Mine has been coming on for the last 2 years during the winter time only on a cold start up first thing for few secs.

 

Thanks for your message.

I just fired up my car, and the light just flashed for like 0,3secs. And now here is +1C warm. So this seems to be weather related. Those warnings were showing longer when it was about -6 to -17 C cold here.

I wasn't getting the warning on cold mornings, just got it once and then the engine went bang so I can't really offer any advice on the cold starts

Decided to take the plunge and get my engine replaced, now the gearbox is playing up!!!!

 

It's common, but unusual at 60k. Most seem to do over 100k without the seal going. There was a theory too that the seal may harden due to diesel ingress too. Caused by previous failed regens. Whether this is true or not, I'm unsure.
I'm on 43k with my 2.0cdti auto. It's 6 years old in Jan too. The pick up seal is a good but cheaper to change on the auto too, so I'm thinking about changing it whilst I have the timing belt/water pump done too.
You could go on forever though with preventative maintenance.

 

I've had this oil pressure warning light lit permanently for the past few days on my Vectra C, petrol engine. Did an oil change, checked the oil level, but the warning light refused to go. Should I be worried about something more serious?

 

If the engine isn't knocking, then it may just be a faulty oil pressure switch (if you're lucky)!

 

Yeah, oil treatments. Have being toying with the idea of using it but I'm always scared. Heard different stories about it from people. Some good, some not so good. But adding oil treatment in a 20w50. Hmmm. Even though we have very high temperatures here, but still... Might give it a try.

 

The old Minis used to use 20W50 and I used STP oil treatment on more than one of them with no issues.

 

As it sounds like your engine is on it's last legs, I'd give the STP or similar a try. 20w 50 is thick oil. Although the wife's Abarth 500 uses 10W50 (not cheap oil), surprisingly. Sips a little too, around 1/4 of a litre every month, has done so from a year old, when we bought it. Fortunately it's not increased, but it costs around £30 for 2 litres. Mine with the same engine as yours, uses no oil between changes.

 

Right according to the owners manual from the factory you should only use Dexos 2 oil of either 5W30 or 5W40 ( down to minus 25 ) or 0W30 or 0W40 ( below minus 25 ) no mention of using an oil of the thickness of 20W50 on the common rail turbocharged Diesel engines.
As you know the first figure followed by the W tells you the low temperature viscosity & the 2nd figure tells you it’s high temperature viscosity.
Within those figure of each oils viscosity the quality of oil is more important than the viscosity , so either of the stated oil grades above would be safe to use without causing long term engine damage.
One time use of ACEA C3 is allowed between oil changes.
Only oil meeting Dexos 2 is recommended or use of the long life GM oil GM-LL-B-025.
No mention whatsoever of ever using a 20W50 in this engine no matter how high the temperature the engine operates in.

 

I understand that, thank you. You said something important, which is the most important thing about the oil is its quality not viscosity. I would switch to a 5w40 or 10w40 fully synthetic when I eventually replace the engine. I think it would be a waste start using that oil on this worn out engine. Let me kill it first [emoji4]

BTW, it's a petrol engine, not diesel engine. Most cars here are petrol engines. You hardly, if ever, come across a diesel engine car.. only heavy duty vehicles and some few specialized vehicles are diesel.

 

Bloody hell this really illustrates why it's a bad idea to tag on to an old thread,
petrol/diesel,confused,who cares

 

Lol, same. Didn't even notice the thread was for diesel engines until Fred mentioned it.

 

No way i carnt believe am reading this my car done exact same down manchester 2 weekends ago loud banhing am a girl dont know nithing being told loads of different things is this true needs new engine please ?

 

Give us the full picture , then we can give more accurate advice.

 

Came on oil pressure low stop engine then it cut out loud banging noise when started up

 

Usually the knocking noise is the crankshaft banging around. Low oil pressure means the crankshaft suffers from excessive wear from the long time of oil pressure being low. When the oil pressure warning light comes on it’s usually too late as we found out to our cost on the gaffers taxi fleet. Don’t spend any money replacing parts until you know what the damage is your dealing with , for instance ours had the oil pump replaced , the cam belt & tensioner replaced , the clutch & DMF replaced , yet in the end it was the crank knocking. £2750 for used replacement engine.

 

I will have to try amd get someone to have a look at it gutted i only bpught it gew days before hand 60 playe diesel 2.0 cdti

 

Nobody on here wants your eyes, you will just get good, honest, impartial advice.

 

Anno thats why i asked am on about different prople av tried to ask i meed someone with diagnostic a think would that work
