Peugeot hdi not accelerating fully and oil leak from turbo

My peugeot 1.6 HDi 2004 307 has started not accelerating fully. Had it serviced and put fuel cleaner thru it. How long for this to work, car is better but not fully back to normal and i've done 150 miles so far. Also an oil leak from turbo, not a lot but should i be worried about the turbo needed replaced? would these things be connected?

Change your engine oil along with oil filter because the same oil is used to cool down your turbo and any dirt means you're going to damage your turbo. Also check the diesel/petrol filter and replace it if not serviced in last two years. Check the hdi pressure (computer diagnose in a garage) because if it is not high enough you can't gain the desired acceleration. If injector seals are leaking then obviously pressure leaks. Clean your turbo sorrounding and check the leakage of oil. In solenoid area If its not enough to drip down or just a little amount that sits with dirt then don't worry (as caused by solenoid seal wear & tear) it has enough life to cover another thousands of miles. Find this solenoid and let it replaced. But if it is from your turbo fan then it doesn't comes out but goes directly in engine to burn with fuel and you can't even find a drop around your turbo housing. Best way is to keep your car serviced in regular intervals.

Yes these suffer bad on faulty turbos, i think yours is dead, let me know how u get on.
i know they carbon up inside which stops the oil getting in, really u need another oil change between servicing.

Peugeot 306 d-turbo rev jumps accelerating


Hi

It could be a number of things, I would check the EGR valve first as that is quite common on the HDI EGR "exhaust gas recycler" reuses any unburnt fuel in the exahust gas and forces it through the engine to keep your emmissions down and improve economy. often these get mucky so you can remove them and spray them with carb cleaner! do not use anything else to clean them.

To check also any air pipes that have splits. tears, rips etc have a feel around the underside of each air pipe as again this can ause that fault.

Lastly check the air mass sensor going into the air box, I cannot reacll where it is on that model but they are very obvious once your looking at it. normally a wire going into the main air intake of the car, unplug or unscrew it and again clean with carb cleaner and refit.

try these before you pay anyone, lastly it could be an injector leak sucking in air, you can test this if you can get to the injectors, poor a little water around each one and see if they blow out any water or bubble up and **** the water in, this can be a cheap fix but the labour invloved may be expensiove, in all honesty buy a haynes book as its pretty simple just takes a while.

Hope this helps, if you are unsure what I mean then get back to me and I will explain.

Regards
Dan

Peugeot 407 2.0 hdi lots of black smoke when you put your foot down past 2000 rpm


The reason for the black smoke is that it is not getting enough air to burn the fuel completely.It could be a blocked air filter,obstruction in the air intake system,blown turbo,hole in tube between intake manifold and turbo,or a fault with the fuel system and injectors.

My 307 hdi does not accelerate properly


The electrovalve that controls the turbo waste gate needs to be changed it costs around £40. It is located on the front lower part of the engine block. I have done lots of them they are a common fault after about 50000 miles.
