wheel barely spins, Droning noise, hot caliper , what is the problem here ?

Ideally there should be no oil in the throttle body.....I’m surprised the thing is still working, quite frankly!
This quantity of oil here does come from the turbo. I see no reason for the pcv valve to be faulty as your engine isn’t chuffing fumes from the oil filler cap.

Normally oil in a throttle body is a blocked breather. Well it was on my omega 2.2 petrol.

I wouldn’t worry about it tbh. It’s a 200,000 mile car. You have done well to get it this far

Hello.

Where is the breather and will cleaning it possibly solve this issue ? Thanks

Hey John.

Can a pcv be cleaned out, what about if I find out where the breather hose is and clean that too ? do you mean you are surprised the car still works or the throttle body ?

EDIT : I think I need me some pot, I don't even smoke the stuff !
 
With the throttle body in that state I’m quite surprised that the car ticks over reliably and the engine management light isn’t on, but if all is well then just flush it out and put it back together.
Positive Crankcase Ventilation is a pollution reducing measure and if you can find any air pipes leading from the crankcase area to the air intake (sometimes immediately after the air filter) make sure they are clear.
I’m only generalising here, I’m not familiar with your engine so I can’t advise where they are.

Hey John.
Yes my car ticks over brilliantly , the engine management light isn't on but then again the engine light is not working and never has worked since I had the car, probably a bulb or something.
I thoguht about flushing it out and putting it back together, but I assue it would only be a few days until it needs emptying again and it is quite a fiddly job
Is electrical cleaner okay to use on the throttle body circuit board ?

Could a positive cranckcase ventilation be causing this issue, does every car have a pvc ?

thanks
 
Sorry to upset you but with the light not working would mean your car would fail an MOT.

Andy

sorry but no, I have taken this car for 3 mots including at halfords ( one of the strictest mot places) and none have mentioned that the engine light does not illuminate
 
For sure I have to agree with Andy there (y)
Anyway, back to the car.....
All engines produce fumes from the crankcase. These fumes are toxic and used to be allowed to escape to the atmosphere. Now though, they need to be burnt so they are fed back into the induction system of your engine.
Your engine doesn’t produce excess fume so forget about that one.
The oil in your throttle body is coming from the turbo, and its getting through the seals between the electronics side and the air tract of the throttle body. Clean the mechanism up with any solvent that isn’t too agressive - brake cleaner will do, as will electrical cleaner.

Theoretically, the MOT tester should see that the lamp illuminates before starting up......and then notice that it extinguishes once the engine is running.
Maybe they just missed it!
Mottie will be able to clarify this one.

Hey
Thanks for that useful information.


Could it not be a case of simply cleaning out the breather thinigies and pvc thing ??

I will take the throttle body off again and empty out the oil and clean down the circuit board, but I am sure it will only be around 3 days until it is full with oil again, it is quite fiddle job and I don't want to be doing this every few days.

I think if the turbo is failing, it is time for a reconoditioned turbo to be fitted. As I say the car engine has been excellent and never let me down so I feel confident that despite it's mileage that it is the right decision to swap out the turbo, plus it will be a loearning curve for me.

It will cost me either way, if I don't get the turbo swapped out I would have to reduce selling price for the equivelant of what it would cost to replace the turbo, I can replace the turbo myself .

edit : can the bulb in the instrument panel be changed seperately ?
 
I can only say what I would do if the car was mine.....
Forget about the engine management light......the dash has to come out which means steering wheel / airbag disconnected, more than likely. Maybe it was disconnected by a previous owner??
By all means replace the turbo if you want......we have advised about the economics of this but its up to you at the end of the day. Have the existing one rebuilt is my recommendation.
I don’t think you have a problem with the PCV system, the oil is coming from the turbo. There is a good chance that the intercooler will be full of gunge too so cleaning that out could be a good move.

hi
I was considering buying a reconditioned turbo , is that not basically the same as getting mine rebuilt ? reconditioned turbos are rebuilt as far as I am aware.
A reconned turbo cost about £200, manifold gasket set about £20, so around £220 for a repalcement turbo. Also I won't have to reduce the price by a few hundred £ and I'll be glad someone else is getting use 9f the car after all the hard work I already put into it.

Is it worth trying to clean out the pvc anyway ?

Where is the intercooler please , I will look into getting that cleaned out . thanks as always

what would you estimate my car value at, 200k miles almost, 1.9 cdti front and rear parking sensors, 57 plate ?
 
If the turbo comes from a reputable, British, company then all will be fine......of course we don’t know where these units come from so the risk is there.
My experience:
Turbos from breakers yards....absolutely crap.
Rebuild the turbo youself? No - they need perfect balancing that we just can’t do.
Dealer prices? Ye gods, a variable jet and pitch turbo was nearly a grand from Renault :eek:
I’ve had 2 turbos rebuilt by turbotechnics (1 Escort RS, 1 Mitsubishi) and they were perfect
If I need one now, the motor factors offer exchange units.
Expect to find the intercooler at the front of the car, in an air stream.....its an air radiator after all, but some intercoolers are on the top of the engine, with an air scoop on the bonnet.
As for the value of your car, expect astonishingly little, unfortunately....its worth more to you than anyone else but We buy Any Car could give you an idea.

hello

. I intend to buy from a reputable british company, there is a turbo rebuild place wirthin about 3 miles from me so I may see if they can offer me anything.

. I would not but a turbo from a breakers yard

. I will not be rebuilding the turbo myself.

. So the intercooler is a radiator, how doeso il get in a finned radiator ?

thanks
 
Oil that is present in the air pipes ( including the throttle body) will also be present to some degree in the intercooler. If you can find it, its worth taking the pipes off and checking if oil drips out.
John :)
