lets discuss 2.0TFSI crankcase ventilation : PCV options etc

[john_o]

lots of talk and pictures on various threads of the state of our inlet valves due to breathing all the fumes....
1. golfmkv.com + using seafoam to clear
2. jonnyc's S3 rebuild thread

Im coming from the position that it does happen btw.
So cmon knowledgeable people what can we do?

I think we should also consider the cars mileage at point of change and any remedial measures you may be able to take before changing the breathing?

what Im looking to do is clarify the possible stages we can apply.
List the change and the approx cost, is it MOTable , any downsides ?
e.g. simple venting , BSH kits, catchcan .....
intention is to add data to the FAQ

EuroJet PCV fit.

Basically an uprated check valve & hose in the OEM location - certainly uses a hell of a lot less oil that before, and cheap too.

£40-ish
No issues with emissions for MOT
No downsides as far as I can tell after 6 months.

id want mine to be clean then do the fix!!..............

Does the Eurojet get any issues with recirculating moisture into the engine?

From what I have heard, the catch can system tends to capture a fair amount of moisture as well as oil and crud

I may well go this way if it is a sure fire way of passing emissions without having to empty a can every month or so. Also with the catchcan I've heard reports that the entry pipe can get blocked as well as issues with freezing in cold weather.

I'll not have any deposits in the engine ports, valves inlets etc once I've swapped the block over to the new one and so will be starting from scratch so to speak.

^^^ Mine had lots of moisture/condensation in the can as well as foamy oil.

This was the content of mine after less than 2k miles running the BSH Stage 2 Fix: -

OMFG

How on earth does the car cope with all that sh*t without a catch can then?

I gather the result of not having a catch can is inevitably baked deposits in the intake area.

The only other viable option would be to vent to air then and when MOT time comes around move back to the PCV. Assuming you can put up with the oily smell

I don't see how it could, as it is a completely closed system from the atmosphere, just like the OEM one - it just has a much stronger check valve to cope with the increases in pressure seen from mapping. I certainly don't have any mayo in my oil/on my cap/on the dipstick

I was chewing through a litre of oil a track day, doesn't touch a drop now and I've had it on for a 'Ring trip & 2 track days.  Maybe the simple things just work well?

What you see being caught in the catch can will recirculate into your engine with the EJ fix.

If you don't want the catch can for whatever reason then I suggest your get the BSH revamp in preference to the Eurojet fix. Either of those two will pass the MOT.

Should you decide that the revamp isn't enough after buying it then you can upgrade to include the catch can without paying the full cost of the stage 2 catch can kit.

As for the "I've heard reports that the entry pipe can get blocked as well as issues with freezing in cold weather" I wouldn't worry as a) in the UK we don't experience the prolonged sub zero temperatures where this issue occurs and b) the BSH catch can has been redesigned without the steel wool  plus the port flow has been reversed from version 1.

With the BSH Stage 1 fix, all that mayo gunk is just going to get blown back into the rocker cover isnt it?

[tony_danza]

The mayo is a result of being exposed to a damp atmosphere, vapour condensing in the catch can. There's no mayo with the OEM system, so how can there be with the other sealed ones?

....A good point but, as I understand it, you'd have to remove the head and clean the (?)valves(?) - Either not for the faint hearted or expensive.

Perhaps it's rather like giving up smoking - I gave up about 20 years ago and understand that my lungs will have 'self-cleaned'.

[joesgti]

yea, but i doubt you car engine has 'self-cleaning' in it!! 

[RedRobin]

yea, but i doubt you car engine has 'self-cleaning' in it!! 

....Doubtful perhaps, but if V-Power really does have 'cleaners' it's logical that some 'self-cleaning' might occur.

It's a valid question though because most of us won't be removing our heads (the engine's heads that is).

I used to run Forte treatment through my diesel MK4, I know there's a petrol version of the stuff too - I usually laugh at stuff like that, but it really did strip all the crap out of my motor.
