PCV hose, delete.

[Czar]

Now i'm sure most if not all of you are aware of the issue attaining to the N14 engine, which has the issue of excessive carbon build up on the inlet valves ?

The usual method is to fit an oil catch can or use a cleaning additive such as Seafoam, BG K44 etc etc or maybe both, there has been discussions and I have mentioned this too, about the fitment of water/meth injection to help remove and control the excessive carbon build up.

For a while now I have been testing another solution, and this is to completely remove the rear PCV hose, which feeds the crankcase gas oil mist residue directly into the base of the inlet manifold, which in turn is pulled up into the incoming air flow and finds itself being burnt onto the inlet valves.

So the following photo's show what I have done as another alternative to combat this issue.













And all is well and good.

NOOOOO!!!! I hope I am wrong and I have misunderstood what you have just done but have you completely blanked of the PCV valve?

If you did then why? PCV valve is important. You cannot blank it off. The engine needs to breathe through it to let blow by gasses escape. If you blanked it off then you are going to kill your engine in the next day or two.

Do not worry the man above knows exactly what he is doing and why he is doing it..

Czar knows more than most on here about the R56 engine and it's problems !!

ok cool

I am interested to see what he is doing and his alternative to blocking the PCV valve

Hi guys,

have any of you tried this solution. would durely like to know the effect as i am about to get the two plugs.

Thanks.

Hi,
I am a new member and was just wondering if there was any more news about PCV hose delete ?

What would you like to know ?

Probably where to get the blanking caps ?

If that's what you'd like to know, all you have to do, is get yourself to your local Peugeot dealer, and ask them, for 2 Blanking caps, part No: 0361.S4

This is not a new idea. I have been running this mod for about 6 months now when I read about it on these forums.

If you look at the new mini cooper s engine it has the delete alrdy installed.


It stopped the coking problem & "super knock."

Czar,

How does this work? How does the engine vent the crankcase gases if the outlet is blanked off?
Does the Peugeot blank piece still allow the pressure to be released?
Why do Peugeot produce these blanking pieces?

I had a minor intermittent misfire which the dealer attempted tp sort by replacing the plugs - apparently a bit burnt? Updating the anti-knock software and finally some sort of fuel additive? Also repeatedly advised that I was using 'bad' fuel. At the last visit the senior mechanic told me that he had done some long term comparisons on his own car and only used the main fuel brands - just the normal octane - not the super. Have followed his advice for six month - no misfire! Still worried about the 'coking' due to the direct injection and the breather return issue so interested in this solution?

Cheers

Hi
Thanks for your reply, I am just trying to get my head round what i can do to look after my car, all i keep reading everywhere is that there are numerous problems with this engine.
I found a link about this PCV delete because i noticed that some people had stated that it was related to knock sensor codes which i have had to have taken off once at the dealer.
How long have you been running this mod ?
does it have any other effects ?
I have also had to change the sump gasket on my car and read somewhere that it can aslo be connected to crankcase pressure ?

Does the Peugeot blank piece still allow the pressure to be released? Yes it vents through the second PCV outlet.
Why do Peugeot produce these blanking pieces? Peugeot do not produce these caps, they are produced by, Norma fittings, and commonly used by many different manufacturers.

How long have you been running this mod ? Over a year, with no problems.
does it have any other effects ? Blanking off the rear PCV, reduces the direct contaminated flow, of the crankcase oil mist residue gasses, and helps in controlling/reducing the carbon build up, on the backs of the inlet valves.
I have also had to change the sump gasket on my car and read somewhere that it can aslo be connected to crankcase pressure ? Crankcase pressure can be responsible for gaskets/seals leaking, that said, the amount of crankcase pressure varies, from engine to engine, manufacturer to manufacturer.

I have recently noticed that cold start rattle noise but not on idle and not very often at all, only when pulling off under low revs and for litterally a few seconds.

I had the timing chain tensioner changed 12 months ago although the noise hadnt started then, i had it done as a precaution

thanks

Probably, as it's NOT a factory fit, nor a BMW MINI recognised/recommended solution, for reducing crankcase oil mist residue, entering the inlet manifold directly, escalating the ever problematic, carbon deposit build up, on the backs of the inlet valves, of which BMW MINI UK, have not recognised this as a concerning issue, for their customers, old or new!

The N14 engine was used in US spec Cooper S models through the 2010 model year.
