White smoke when idle

[Agis]

When sitting idle it will start to smoke a little of white smoke from the exhaust and will puff more when I rev it. It's not a lot but it is noticeable.

A bit of history just before the white smoke happened. I may have overfilled the engine with oil, then drove off on the motor way and at about 10 miles later a huge oil leakage happened. The engine lost a lot, if not all, because of a loose timing chain tensioner. Towed the car to a local garage where they tightened up the tensioner and refiled the engine with oil. Two days later I took the car to Peugeot for inspection. They said that the tensioner's o-ring need to be replaced. Changed that, they also topped up the engine with oil.

The car started to smoke a couple of days later, or I haven't noticed earlier. Annual service is due and Peugeot will have a look at it. I hope it's not the end.

The THP engine is known for putting out a little more smoke than others.

Do you have any warnings on the dash, is the car behaving in any unexpected way, down on power, showing higher temperature readings than it should.

White smoke could of course be an indicator that there is some water in the oil. Check under the oil filler cap to see if there is any sludge or white residue.

If the only symptom is a bit of smoke (obviously not clouds of smoke) then you might be ok. The service should throw up any major issues.

No warnings or power loss, everything appears to be okay, apart from the smoke. It's quite a big puff really, it didn't do that before. However, the smoke is only there when it's idle and when I rev it from idle. There is no smoke when I am driving.

Is the EGR working correctly? Maybe some cleaning would help as well.

Blue smoke is normally associated with oil related problems, my car has always put out quite a bit of steam from the exhaust from cold but does disappear once warmed up.
Keep us informed of how it goes.

Maybe see you in Holland at the Euro meet, noticed your name was on the list :thumbup:

Smoke coming out of exhaust is never a good sign. Except for 2 stroke engines. No matter if on cold or warm engine, there should never be white smoke coming out of exhaust (the other white smoke is just water, but that is fine).

First I would check the EGR (Exhaust Gas Re-circulation pipe + valve on our cars). It has to work flawlessly, especially on turbocharged cars.
If that part is proven to work correctly, then I would check for worn valve stem seals. If oil pressure drops (at idle) oil is slowly crawling past them into the combustion chamber and burns. As soon as the engine speeds up and pressure rises, the worn seals "seal" again and it stops burning oil.
I never have heard about blown valve stem seals on the THP engine. But shiat happens.

You have overfilled the engine with oil. Now hopefully the oil fill is correct, so I would just drive the car for a while and see if it still burns oil at idle. Maybe it only did short after the overfill happened.

I had the RCZ at the garage last week, they said that it is normal to smoke after been sit idle for some time. I switched to Castrol synthetic 10w30 oil at the previous service, I wonder if that would cause the engine to smoke. Will keep you posted.

So I had the RCZ serviced this week. Put new iridium spark plugs on, changed the oil filter and old oil with fresh Total Quartz INEO ECS 5w-30. The car smokes when it is warm and left idle for a few minutes. I hoped that the Castrol oil I put six months ago was causing the smoke, but that is not the case anymore. The mechanic, an independent Peugeot specialist, keeps telling me that it is normal. I may not be an expert, but this does not look normal to me... :crazy:

No that doesn’t seem right to me :eusa-think:

 

[RCZIain]

I agree with Neil, that's not right.
My RCZ had nothing like that coming out of the tailpipes.

That is not normal. Many causes when engine hot and at idle with a rev, but these two spring to mind: the valve stem seals, or the turbo charger oil seals etc

I would also consider changing your choice of mechanic.

I'll do some DIY this weekend to upgrade the Diverter Valve with this one https://gfb.com.au/products/blow-of...-mini-citroen-and-peugeot-application-detail/. Will keep you posted. :ugeek:

Flanners, that is exactly what is on my mind right now. I'll also have a look at the Diverter Valve, take this out of the way before getting onto Turbo or valve stem seals.

Thanks

I can’t imagine the emissions can be too healthy with that lot coming out of the exhaust :eusa-think:

He will be ok it's not a Volkswagen :lol:

If it was they’d have said it was a design feature :eusa-whistle:

Wow, mil-spec RCZ option; no doubt in khaki or camouflage wrap. :clap:

How did the upgrade go?

Agis, did you manage to figure out what was the cause? My car is doing the same :/
