Do you think we have found limit of the internals of the B207 standard internals
[color=rgb(255,0,0);]Dunno. Too soon to tell based on just 1 case me thinks.[/color]
Is ultimate on dutch software
[color=rgb(255,0,0);]Yes.[/color]

Are you all on 2.0 ?? Standard internals

  Yes. (though exmantaa has an lsj, and speedster4fun has a Z20NET) Upgrading internals seems to be a UK thing for now   We only have 1 guy with a harrop on his Z22SE. (easy 350hp, but eating oil like crazy due to the wiseco pistons)  

I think I'm the only person on the dutch software plus harrop on z22se engine. Could you explain more about the other car eating oil, is it on track or just general driving? How much more oil is he using from the last stage of tune he was at and is it lost through burning up or throught catch tank etc?

Think Nick is to Luke As for the oil usage could it be down to PCV system ie the vacuum increased in the inlet which is pulling the oil out of engine and through SC and inlet This is why I want to put it on the exhaust direct so the vacuum is less Thoughts ??

Forgot about Nicks car but I think he is running different pistions then mine. Yeah I think it is the PCV system that causing it. Mine seems to be spitting a bit of oil out of the breather as mine is venting into the atmosphere. When I was on the m62 with just over 300bhp it wouldn't hardly use a drop of oil. I did a track day at anglesey and it was a boiling hot day and I was out all day, when I came to top it up it used about 150ml of oil in the whole day so ive never needed a catch tank. Now with the harrop bolted on and doing a track day there's seems to be a bit of oil coming out the pipe and I used about 300- 400ml of oil maybe. So it looks like I'm going to need a catch tank but would be nice for it to not use so much oil compered to before. Then again my PCV is still blocked up but I don't want to unblock for oil vapour to get into my inlet manifold.

The valve is only for low revs Luke At higher revs it closes automatically

[haggi961]

It's using more oil but i know its not burning it as I can see oil from where it's come out the pipe.

[CHILL Gone DUTCH]

I wonder if we can put some kind of restrictor on to reduce the vacuume The problem with blocking it up Luke the low revs Gassed are not getting out and building up so when you get to higher revs there's more to release / come out probably increasing the oil escape

I would love to unblock it but I don't want to be cleaning oil out of the laminovas again. Mines has been blocked up since stage 3 and it's all been fine. It's as soon as I got the dutch software it then pushed past the phonlic spacer and forced its way into my inlet. Now with the hole blocked up with silcone in my head there's no chance it can.

[CHILL Gone DUTCH]

It's probably down to something mechanical rather than software ( Harrop maybe ) Also if you have block the orifice to the cam cover the oil must be pushing past the rings/Pistons Which means the pressure is building up in sump Due to it having no where to go

[haggi961]

No I blocked the hole up in the head that goes to the inlet manifold, the normal breather is still working as it should venting into the atmosphere.

[CHILL Gone DUTCH]

Aahh Ok Sorry miss understood what had blocked up

The guy also had big oil loss when on M62 stage 3. He even resleeved his engine, but the problem is with the pistons.

I don't speak the owner that often unfortunately.

smiley haggi   anymore... deadline is tomorrow  

Just back from Egypt, just made it by 10 mins - I'll have one as well please joe

Chill, I've just opened up the pcv system as we discussed. Will this significantly reduce the cooling from the laminovas? I have no it run the car much to establish whether there has been any reduction in oil consumption.

He still has the oil problems? (Driving behind him on track was not fun; 3" noise & smelly)

 

Thought that after the resleeving + new stock bore Wiseco's it was now under control...

I'm afraid so.

Not until they block up I would strongly recommend putting a sealed catch tank in between the cam cover and inlet I'm also thinking about going straight in to the exhaust but this is going to need some more thinking and find someone with experience in doing it I've also had a other idea of restricting the vacuum from the inlet incase the vacuum is actually pulling oil straight out of the engine because the vacuum is a lot higher than what system is designed for Again this is going to need some extra thinking and some discussion

How are you running the PCV just trying to get more information about trying to reduce this oil which everyone is suffering from at different rates it appears Also I was speaking to someone tonight about the piston rings Using a split ring rather the the solid ones on the wiseco Pistons Has anyone tried this

[CHILL Gone DUTCH]

Also could it be the oil itself breaking up causing the issues The more I think about this the more questions I have Maybe Tom )fezzaus can comment about the oil itself

[fezzasus]

Typically oil loss happens two ways:

 

1) evaporation of the thinner fraction of hydrocarbons that make up the base stock of the oil (this is known as volatility, different specifications have different volatilities - oils with MB 229.5 and 229.51 claims have the lowest.

 

2. mechanical loss through gaps in the engine; past piston rings, valve steams, leaky bungs ect. Most engines with aftermarket pistons will see higher oil loss as they will have a looser fit, and different thermal expansion profile which means they will be looser when cold.

 

Thermal decomposition of the oil will make it thicker and less likely to evaporate or leak.
