A lot of white smoke ? you can get a lot of "steam" & water trickling form the tailpipe as the engine warms up especially after the cars been standing for a while which may be due to atmospheric condensates
Fuel economy could be a few things ?

I have had a small amount of white smoke from the day I got mine. Also, my fuel economy is not the best. I did consider it might be something to do with the way I red line it in every gear while out 🤔

I wear a pair of ultra light shoes but still not a good return on economy & I have read different fuel consumption for these variants the best way to overcome heavy fuel use is try & keep the Engine fully serviced & quickly get into 5/6 gears as per the traffic allows but I never red line the car as this empties your pockets faster ! 😁

I have a service contract on mine, so it’s always been done by my Peugeot dealership.

I thought the red line was the engines way of telling you to change gear 🤔

ok so the specialist thought the oil leak was the rocker gasket, and while replacing it checked the chain and timing.
Good news is that the chain and timing are fine.
He has now noticed that there is an oil leak coming from under where the oil filter housing is, the oil/coolant exchange area. I mentioned the possibility of the banjo coupling on the oil feed to the turbo, and he said they look fine and the oil leak is starting below them.
He mentioned the spark plugs look pretty burnt out, and he had a low reading from the vvt solenoid, was showing 6% when he was expecting ~50%.
He tells me he is not good with oil leaks, it sounds like he might be giving up!!

Also, he said the ECU doesnt match the engine.. and because of this he cant get detailed diagnostics...

The oil leak around the filter housing might be the sealing ring inside the cover assuming it has one fitted or even the housing has been cross threaded when repalced after a filter change ?
The problem regarding the ECU is that each one is configured to the individual car so I'm wondering if you have a replacement engine or the car has been remapped? which could point to why he can't get a response from a code system check although if he is a Peugeot tech he can wipe it clean & reinstall the correct parameters for that ECU assuming he knows what coded ECU you have in the car ?
Burnt out plugs could mean they were overdue for changing & also the Engine may have run too rich for long periods maybe overfueling due to pump fuel pressure issues
The low reading on the solenoid could possibly be due to the ECU as it may not recognise any or very poor configuration between the units to calibrate for the timing advance etc
Overall I'd say considering the problems you have found its a miracle the car starts & drives at all as god only knows whats controlling the functions on the Engine ?
Does your on board diagnostics systems still work on the screen & what sort of codes if any are coming up on a scanner ?

I replaced the filter recently, the sealing ring is there and the housing is not cross threaded As far as I can tell.
the only code coming up through odb2 is p0016 but the Peugeot specialist is saying its not coming back now.
yeah this car has been a nightmare.
I was thinking the oil leak might be the oil filter housing gasket?

Peugeot specialist tells me that he can’t wipe and replace the ECU parameters as this is not something the genuine equipment is able to do, for this kind of thing I would need to go to an ECU specialist.

I thought he said it was the wrong ECU & yet he is getting a code from somewhere?
Oil filter housing is a Possibility the only way you may find the culprit is to degrease off all the oil around the engine go for a short run then jack it up & do a top & bottom visual check just maybe you will see a drip or 2 give it a good going over then just maybe you will get lucky

Do you know if the car has been remapped ?
If he is a specialist he should know & have the Peugeot data to overwrite & reprogramme the ECU ?
Peugeot instructions to the techs is according to their manual to download the data from their laptops into the cars ECU & start the Engine then do a full systems check before switching off & rechecking before handing back to the customer

Sadly I have no history for the car, it was an impulse buy while I was in desperate need for a car.
This guy is a ‘peugeot specialist’ but it’s not a dealership, sadly they are all locked down where I am.

I understand mate that's the problem with buying secondhand motors if you cannot get any info on their history you have to use your instincts & surprisingly a lot but not all buyers fall for the sellers rhetoric

It’s also far too easy when looking for an RCZ to fall for the first one you see as they are such a good looking car.

All it takes is the seller to say there have been a few people interested in it & your hooked. 🤔

You going to need a remap to sort out that ECU although I'm not 100% convinced it the wrong one for the car I did some digging on your problem & it clearly states that swapping ECUs between 2 vehicles makes it impossible to start either car (Peugeot's tech data)

Yea I’m not convinced either. He said it is an ecu for 308 or 3008 which could be why the vvt was showing as 6% at idle instead of the 50% he was expecting.
Anyway, the good news is I just drove the car over 100 miles and I am seeing no codes!
I might look at getting the ecu mapped at some point for the extra mpg, but for now I am happy, I just need to get this oil leak sorted out :)

ugh oil leak is now much worse :rolleyes:
I am wondering if it is something the guy did or because I did a long drive. The guy replaced the rocker gasket, and I cant see any obvious leaks from it.
looks to be dripping directly under the oil filter, which was his conclusion as well. Oil filter cap itself is dry.
How difficult is it to replace the oil filter gasket on one of these?

I need to check that one it may be bolted or threaded into the block ?

This a schematic of the Prince Engine & shows the filter housings looks like one bolt goes int the side of the block

To conclude this thread, the codes p1336, p0172 and p0087 were caused by the hpfp, and p0016 was cleared by replacing the cam sensor.
Oil leak was from the oil cooler gasket.

during this time i have also done the following unrelated work:
oil and filter change
air filter change
brake fluid change
replaced the rocker gasket
replaced the spark plugs
replaced the drive belt
transmission oil change
wheel balancing
ng4 harddrive replacement (with compact flash) and update
replaced the damaged front grill and parking sensors

Now if only there wasnt a lockdown i could take the car out for a long drive and enjoy it!

i bought this car with front grill damage for £2100. Most expensive part was the front grill replacement parts i had to order from France for £500! the same parts for a 208 would have been close to £80! So, all in i am close to 3k for a 2011 1.6 rcz GT with satnav at 100k miles. i didnt realise the extent of the problems when i picked it up as i was in a rush to get a car after my previous one failed. Probably could have picked up a better example and without damage for cheaper, but at least i know this car completely inside out now and (fingers crossed) there shouldnt be any problems for a while..

Enjoyed reading this thread... glad you got to the bottom of your problems 👍 :cool:

I've had similar on my previous car re the camshaft sensor. I replaced the cam & crank sensors together once & eliminated several issues (codes). Easy job, sensors cost very little and it was a good way to try eliminate issues before diving in deeper.

You've done a lot of non related work (hindsight) that will stand to the car going forward.

Only joined here couple weeks ago and only have my RCZ a week but have done a lot of reading up here (fantastic site & people 😀) and my first impressions are that I will need to watch the HPFP & timing chain / tensioner... and most likely replace them at some point 🙁👍

BTW where is the oil cooler gasket located on the RCZ?

Also, who is "the ebayer who offers repairs for £140" on the HPFP? Can you provide a link? 👍
