PLEASE SOME1 HELP ME OUT

 

Hello mate,

Greetings from Narita, Japan.

I am not privy to V40s so please note that. I believe someone else with more knowledge on the V40/S40 would come in to help, so I'll just give you the basics to go over.

Volvos are very sensitive to scheduled maintenance and a neglected one is sure to give you problems. As to the oil burning at higher revs, it could be due to worn out piston rings, valve guides, etc.. depending on the car's service history as well as how it was taken care of by the previous owner (unless you bought it as a new). Or it may not be as serious.

Make sure that the PCV system has been serviced lately, the throttle body cleaned, the EGR system working properly, etc... Also, be sure that the engine has had a good tune-up in the last 3 years.

At the moment, the best you can do is to clean the engine and wait to see where the oil leaks from, without running the engine. If you do not see any leak with the engine off, start the engine and let it idle until it leaks oil. Locating the leak is half the battle. If it is leaking from the turbocharger, it could be as simple as a leaky gasket/O-rings, or could be as serious as turbine/compressor seals. Additionally, please tell us how many kms the car has on the odometer.

Lastly, when you have your Volvo serviced at a garage, be sure to go to the dealer (but be wary too, as dealers often try to sell you unnecessary parts/services if they figure out that you don't know much about cars) or a shop that specialises in Swedish/European cars.

I hope this gives you some hints until V40/S40 drivers come in to help you.

Cheers,


JPN

hi car has 180000 with full history i have only got it in last 2 months and have had no problems.been driving fine not a noise or missing beat up till now.smoke seems to be and oil coming from turbo area under heatshield..wil it have blew a plug or worse which caused me to hear as if running on 3 cylinders
im scared to start it up again.lol

 

started car again and now running fine but wen tok for drive seems to be no oost and wen should be boost serious missing
wat could this be?????????

 

Hello again,

Well, it seems like there is a leak somewhere on the turbocharger. Again, wait for V40/S40 owners or Moderator Tech to reply, and in the meantime I would try not to drive the car as much as possible until the problem is resolved. If you must drive the car (which I highly discourage to prevent further damage), make sure that the engine does not go low on oil. Check the oil level everyday until the problem is resolved.

I am not privy to the turbocharger on V40, and I can only assume that something is either cracked or loose. What did the boost gauge tell you the last time you drove the car? In case if the turbocharger is beyond repair, your best bet would be to install a rebuilt unit.

Sorry I could not help you better.

hi yes using oil and quite a bit.car has got no boost guage in it uk standard t4 v40
i have a new turbo here to replace do you think this will sort out all trouble or is there anything that could be at fault in engine
car running smooth up until turbo boost needed and no strange noises etc

 

Sounds like you might have a couple of different problems.
First I would inspect/replace the PCV system. If something clogs in the system it will cause the engine to suck oil into it and burn it.

The misfiring might be from that or a bad spark plug or coil.
Do you hear any noise when it should be boosting?

 

it is boosting more often than not and turbo seems to be whistling noisy no other bad engine noises or rattles but wen should be boosting it is splutttering and dying out

 

Is the check engine light on?
If so get the codes read out of it and let u sknow what they are.

 

no no lights on check lights or nothing

 

had a look under car also and looks like oil residue all underneath car leading to back of car

 

Maybe try to have the codes pulled and see if there is some but didn't make the light come on.

 

dont you reckon this will just be turbo.a replacement turbo would solve dont u think????

 

Sorry but no I don't.
There is many things that control the turbo.
The ECU is the main thing that controls it.
When was your last tune up including Coil packs and wires?

 

ive nt long got car and only done around 100 mile in it so cant be sure wen..sorry
would this ecu or other make my turbo use loads of oil and smoke coming from turbo area and also slugish and dying wen boost

 

No not the ECU itself. But sensors sending signals to the ECU.
A clogged vent system will make the car burn alot of oil. Maybe even die under boost.

 

ok thansk very much so wat do you reckon should be my first things to check

 

Check vent system for cloggs.
Check vaccum hoses for leaks.
Check boost controller hoses for cracks/splits.
Maybe if you can have someone try to read the codes. There might be codes eventhough there is no light on.

Sorry I also forget and am in the middle of the reply when was the last tune-up and coil and ignition wires replacement?

When it runs bad does the check engine light flash when accelerating?

 

no check engine light at all
the car seems to be gettn boost ok more often than not its just burning and using lot of oil and slight whistling noise now coming from turbo

 

You might have a Boost leak. one of the hoses may be bad.
That is ontop of what sounds like a clogged PCV system.
