Peugeot Expert 1.6

Hi - I'm trying to get some answers as to why my expert van revs to maximum between gear changes?

It all started with me overfilling the engine with oil which caused a massive amount of oil to go all around the engine bay, underneath the vehicle and even up the back. I was driving and didn't realise the mess that was happening at the time. I steam cleaned everything thinking no more of it but then on a journey of about 25 miles, once the engine was hot, it started this over revving. I stopped and got the AA to tow me back to a local mechanic. After a couple of days of head scratching, he said it was breathing too heavily and on taking a breather pipe off and going for a very short test drive, the engine bay was once again covered in oil, Having discounted turbo problems, he came to the conclusion that there must be a crack somewhere in the engine, allowing oil under pressure to combust, causing the revving issue. However, I spoke to an ex peugeot engineer who said that a crack was extremely unlikely and that it was probably a split fuel injector. That company wanted £4000 to strip down and thoroughly clean the engine, and test and replace the fuel injector.

I couldn't afford that and no other local garages wanted to take it on, so had to SORN it over christmas and think about what to do in the new year.
I dont need the van anymore but still have thousands to pay on finance (the warranty has run out) so dont know whether to just try and sell it as a non runner or see if I can get a diagnosis and hopefully fix it.
Does anyone have any ideas please?

That sucks. I remember yeeears ago I was doing an oil change on my Peugeot 106 and almost did exactly what you did until it was pointed out that you don't put more than 5 litres in! Glad I averted that, sorry it happened to you

To connect the dots, my thought is that oil is somehow getting into the combustion chamber but maybe that's because I'm being primed to think that and greater minds than I have discounted it.

I can't think of a reason why overfilling the oil would cause an injector to fail. Did they explain their reasoning?

Re: Peugeot Expert 1.6

I just asked my brother who had exactly this on his old Peugeot 405 1.9TD

He solved it with:

- Drain the old
- Refill (with the right amount!)
- Clean the air filter housing
- Replace the air filter

Makes sense. If oil has soaked the air filter it'll end up being dragged back into the engine through the air intake. Has anyone checked that?

Re: Peugeot Expert 1.6

Thanks for that! It has given me a glimmer of hope, and i will be getting in touch with a few garages today to see what they say.
Webuybrokenvans have offered £3500 as a non runner so I at least have some options now.

Re: Peugeot Expert 1.6

Is it smoking? I did it years ago with an old Mk2 Escort. I blew some piston rings but being petrol it was nor running on its own oil just burning most of it and running like crap. That would explain your revving between gear changes due to diesels being able to run on oil.  but before panicking do as mentioned drain and re do the oil. Find out from the user manual how many litres your van takes and put that amount in the one container. Drain oil and filter and refill.  You got an intercooler? If so pop the pipes off and stick a finger in to see if its soaking with oil as that will want flushed out if so and if oil has been going round that area its probably been blowing into your turbo. Talking of which if the pressure in the engine is that hight the turbo is oil fed/lube. The pressure may have been blowing that into your turbo what will blow it into into you intercooler and its chucking in clean air. Intercooler sucking it into the engine and burning it with the diesel. To much making it rev like mad. Fingers crossed drain and clean fixes it.
