PCV Valve and burning oil - any advice??

[Kynance2000]

Hi there,

I'd be very grateful for any advice on where I can source a PCV valve. I'm hearing that they can only be got as part of a £313 cylinder head/new rocker part.

I'm told that this may be the cure to the rapid oil burning (though no smoke) that I'm experiencing with the 82bhp engine. 16 reg and about 50,000 miles.

Any other advice welcome too.

Many thanks

It needs further investigation, it's either dropping oil or burning it, how much oil is it using ?

Any gunk under the oil filler cap or dip stick or drop in the coolant level?

rev the engine to 2000-2500 rpm and let off the throttle, get someone to check for smoke

what is the service history on the car

If the car is an oil burner as a result of stuck piston rings and glazed cylinder walls which is the most common thing on any Toyota engine then a new pcv valve will not change or help anything.
At these low miles pcv unlikely to fail. 
It could indeed be a reason if the car has a few oil changes skipped and engine is really contaminated with sludge. Check what is engine condition inside by removing the oil filler cap and use torch to light up , see if it looks clean metal or it looks darker yellow-brownish colour with black small particles all around. What is oil colour, condition, dipstick how it looks, any darker formation on it where the readings marks? And at the end check your tile pipe, if dark and oily inside, swipe a finger and if it gets black , yes you have an oil burner, if the exhaust is rusty yellowish  and clean , free from oily crude then the problem is elsewhere, as mentioned above oil leak or something. 👍 

Can take some pictures of all the areas and share with us.

Something not right here. If its got 82hp then its not a Toyota engine. You are not talking about a C1/108 with the 1.2 engine are you?  I think they are 82hp.  If its the 1.2 Puretech then the piston rings get gummed up with carbon and they start smoking.  Its a terrible engine and would probably need a rebuild at 50k.

You've got me!! 

It is the C1 but I was told they are the same Toyota engine as in the Aygo and was desperate for info. Apologies if I misled.

I'm hoping there is another solution to a rebuild – but it sounds like this is a known issue 😞

Its a PSA (Stellantis) engine - French, not Japanese.  Best thing to do is get rid of it ASAP because it will grind you down. Don't sell it to some unsuspecting private buy - put it through the likes WBAC or P/X it.

Thanks for the info and advice. Maybe a Toyota next time...

If you had bought an Aygo, you would been ok, they only used their 1.0 chain driven engine in the Aygo Mk2, probably remembered the iffy 1.4 diesel PSA supplied for the early Mk1s, which soon got dropped, once bitten and all that!, PSA fitted the 1.2 to mainly their 'posher' C1 and 108 Mk2 models so if you car has alloy wheels/keyless entry then good chance you got 1.2 PSA engine, wet belt and all! Although I did notice that very late/last of C1s and 108s seem to only have 1.0 engine, funny that. 

Our lower spec Mk2 108 has toyota 1.0 engine, which I insisted on cos at the time the 1.2 was just too new for me and our 107 with toyota engine been so reliable, so it has proved.

C1 with Toyota 1.0 engine:

C1 with PSA's 1.2 Puretech engine:

If it was the Puretech, like Eric have said: Get rid of it ASAP.

Unlike the Toyota Engine that uses Timing Chain (if you service the car regularly, it will last the lifetime of the vehicle), these engine uses a wet belt.  On paper, this belt will last 60k miles / 6 years before requiring you to spend £400 to 800 for replacement.  More often or not, they failed prematurely

When they fail, you'll get a Engine fault warning on the dash require you to STOP immediately.  OBD2 scanner will tell you engine oil pressure low.  What happens is: 

• The belt sits inside the engine (lubricated by engine oil, hence its name WET BELT)
• Rubber on the belt disintegrated into pieces
• Pieces of rubber clogging the oil pick up
• With the oil pick up clogged, it starving the engine from oil
• When an engine does not get lubrication from Engine oil, Engine dies, Engine replacement.

Friend of mine had a 2016 Peugeot 2008 which was bought second hand in 2022.  Shortly after, the wet belt failed cost £1000 to fix.  Thankfully nothing was damaged and the car was covered by warranty.  2 years later, same thing happened again.  (Yes, wet belt failed in just 2 years.)  Now he's selling the car.

I missed the 85 bhp part

That makes it a 1.2 Puretech (Pureheck) as its a PSA/Peugeot engine a Peugeot forum may be a better place to post -  they can turn into money pits quickly - the wet belt just being the tip of the iceberg

after 2008 all Aygo's have the 1.0 1krfe engine
