I have a 214 Sli (1991) and recently its been giving me a few problems. In the last week or so I have noticed that it has been accelerating sluggishly. It splutters up to 2000rpm then kicks you in the backside.

I checked the oil level today and its drunk over half a litre of oil in 2 months, whereas when I first got the car the oil level barely moved for 8 months when I changed it as part of a mini service. I can see no oil leaking from anywhere obvious (i.e. the filter and the head), plus I have no mayo or coolant loss.

Possibly related but between 4000 and 6000 rpm you can hear a faint grinding noise. Also its spewing black dirty liquid out of the back of it like no ones business, I thought this was because I hadn't been driving it enough recently, but I did 140 miles on the motorway on saturday so surely this should have burnt out all the water in the exhaust?

Edit: This is what has been done:
Oil Change (GTX Magnatec 10w40)
Oil Filter (Halfords)
Plug Set (NGK)
HT Leads (Bosch)
Air Filter (Champion)
Coolant temp sensor (Cured fuel economy issues)
Engine Flush

Edit 2: I forgot to mention that it does not idle smoothly, I.e. the rev counter bounces between 800-950
Any ideas?

not much help i know m8 but someone may aswell reply.


Not sure what your problem might be but it sounds pretty serious but also doesnt sound like the usual suspects(HGF/ecu problems etc) could be worn piston rings or something like that and in that case i cant really see it being worth fixing, maybe cheaper to get a replacement engine, or a new car :(

I forgot to mention that the ecu has already been replaced due to a failure in its ptc heater mechanism.

I have noticed that the fan has never come on when driving the car, but then again the coolant temperature has never gone over halfway and always starts to read after about 2-3 minutes.

Hi there,
sounds to me like piston blowby, massive oil consumption and crap sealing at lower revs, over a certain rev speed, the actions are all happening much quicker so it seals the bore easier. However, a similar problem i encountered on an Astra a few years ago was the head gasket gone between two cylinders, this basically meant the car ran rough as rats below 2/3000 rpm, but when the engine speed was cranked up above the actions were happening much faster that there was less bleed between the cylinders.

The first thing you need to do, in my opinion, is a get a compression test done on all cylinders, this will give you the best indication as to whether it is blowby or leakage between cylinders, if it is leakage and knackered head gasket could account for oil burning, however with knackered rings the oil carry over is pretty huge as well. Another thought might be that if you have piston blowby you pressurising the crankcase and hence the breathers back to the inlet manifold would be carrying excessive oil vapour.

Not a Rover specialist, but i hope this is of some help. Compression testers cost about £10 and dead easy test to carry out.

Good luck

Brian

I have runny black liquid from the exhaust but no smoking.

The engine wasn't cold by any means. I'd driven it for maybe 20 minutes before doing the test, although it did take me 5-10 minutes to get the thing ready.

Hi there, I honestly don't think the oil consumption is that serious given that the engine is 14 years old 1/2 a litre in 2 months is not significant especially if you do an average milage i.e. 1000 mile per month. even 1/2 litre per 1000 mile would still not be over rovers warranty complaints figures.

Black waterey liquid from exhaust is pretty typical from an early 214 also.

As for the misfire this could be a bad connection on low tension side of ignition system, faulty crank sensor? or even fuel filter blockage, not had this myself but I have read a few comments on here saying a change of filter had cured similar symptoms

Cheers :)

Well i have a thread going about the oil consumption part.

My 214 also idles a bit rough, will be idling perfectley at approx 850rpm and then kind of hunt between 800-900rpm for a while untill you blip the throttle....

Have the black crap out of the exhaust aswell, like black soot! :irked:

a litre of oil a week btw!!! now thats excessive! hoping it will be cut down now :)

Well it sounds like the compression test is not too bad, not sure what the figures should be, but they are all within 10% of each other. The sooted spark plug is due to either incorrect burning of fuel in cylinder (could be something simple like crap spark plug or HT lead) or that oil is getting into the cylinder. Is it basically dry carbon burnt onto the spark plug or oil mass on the spark plug?


Clean spark plug off, ensure that the gap between spark plug and electrode is correct (i think it should be 0.7mm) and make sure you get a nice spark (attach HT lead and hold near to engine block with insulated pliers and look for nice spark). If this is all good, put back in engine run for a few miles and get back out and see if it is blacked up again.

Fuel filter is a good idea, I was thinking more on the emissions side. Something that most garages forget on a service.

Placve for parts, found these people the other day looking for mine http://www.sales.bestofbritishrover.btinternet.co.uk/1024x768/index.htm

I couldn't hear the sound from your link i am afraid. Check your air filter, make sure it is not blocked up or too oily, check your crankcase brothers to make sure you aint carrying a load of oil into the intake.

Running out of helpful suggestions.

Regards

Brian
