Re: oil coming out of exhaust and whistling turbo
It sounds like your turbo has packed in firstly the oil seal in your turbo has failed thats why ur seeing oil from exhaust & the whistling from turbo is the vanes in turbo breaking up so i would advise not to use car until new turbo is fitted & inter cooler pipes and inter cooler itself are checked & cleaned for swarf from turbo you can check turbo by disconnecting turbo pipe &inspecting turbo vanes (fins) to see if broken up or any damage to chamber.
Peugeot 307 1.6HDI 110hp The turbo is getting lubricated with engine oil through small hose connected to top section of the engine.. The rhythm of the engine has changed started shaking lil bit. The engine oil is normal on level. Is this normal and is the oil can damage the turbo. Shall I be worried about.. Thanks...

black smoke is not enough air or excessive fuel
if turbo , the turbo is not working and boosting, injector failure
incorrect fuel in system ( petrol instead of diesel)
water in fuel will damage injector tips
Turbos are noisy if they are working. If you have the 2009 6.4L they (twin turbo) should be pretty quiet unless you have aftermarket items installed. If no aftermarket mods have been done have the coupling joint between the turbos and the outlet gasket checked by your dealer. If it a 2007 as the heading says the original air filter and exhaust muffle a lot of the turbo whine but not all.
Clean air filter, fuel filter and turbo filter. Check the inlet and outlet manifolds incl. EGR valve and Turbo gate. If there is particle filter then may be it is clogged. If its a diesel then open the injectors and clean it.
You can fit a turbo to just about any car, the problems lie in changing the inlet and exhaust manifolds to house the turbo of choice and supplying the turbo with oil and water to cool it, also if the car has a ECU getting it chipped to provide the right amount of fuel at the right time.
To be honest if you want a turbo car it is best to buy one with a turbo already fitted as it will probably cost you less to buy for example a Mitsubishi Colt Turbo (around £1500) than to fit a Garrett Turbo (around £3000 with fitting and manifolds) to your 205. Not to mention that the gearbox, brakes and suspension would need to be upgraded aswell.
sounds like you have a turbo with a bad bearing.
pull of the turbo and rotate it by hand to see if it is hanging up.
Most turbos start to make a different noise when they start to go.
Sometimes dirt can bypass the air filter if is not changed on a regular basis and can cause the turbo to fail or become dirty enough to cause it to spin slower, (the dirt prevents the exhaust to spin the turbo at the right speed and the air passing the fins can whistle), it will cause bearing failure after a while. Also if you have too much soot in your exhaust from too much oil, the exhaust side of the turbo can become too dirty to operate properly
hi, this problem could be valve stem oil seals these are cheap to buy but will require the top half of the engine been stripped and rebuilt. If the car has a turbo then you might find that its just a turbo pipe split this is often the case on most cars that have turbo as your is diesel then you should have a turbo. This would be my first choice to get looked at as usually its just a pipe to the turbo has split and this causing the problem your having. Replacing this should not cost to much as it is common problem so look at this first.
Worst case it could be the turbo needs replacing but getting a garage to check this for you is the best bet but hopefully it is just a split pipe going to the turbo. Most diesel cars with your problem that i have worked on is usually one of the pipes for the turbo has a split in it so replacing this will solve your problem ok. let me know if you have any problems or questions and ill be glad to assist you ok.
Hi, i think i answered you in another post. If not then the likely cause of your problem is turbo related the most common cause is one of the pipes going to the turbo has a small split in it causing this problem.
Nearly all the diesel turbo cars with your problem usually means a pipe needs replacing for the turbo this will need to be checked as it can be difficult to find the damaged pipe because they work under high pressure so actually seeing the damaged part can be difficult so check properly. If you are unsure then get a garage to check this as they will know the fault and will have a good idea exactly which pipe is damaged. Worst case of this will be that the turbo needs replacing but this is in the most severe of cases the turbo can blow if the pipe has been damaged for to long as it will be working under the wrong pressure. What happens is when you acelerate the turbo builds up pressure giving you more power when you need it but when the pipe becomes damaged this pressure is lossed and you then lose power and will cause black smoke coming out of exhaust.
Hope this is some help to you but if you have any problems or questions then give me a shout back and ill be glad to assist you further ok
