OMFG :surprised: :scared:
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 :sick:

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 :sick:
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. :smiley:

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.
bacillus:
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?
