Really strangely I did have the 'Toilet Roll' oil breather! So that was one of the first things I switched out. I think the vortex is a much better design but worries me slightly about filtering the oil, as it is less friction but... where does the rubbish in the breather go? So I am pretty fastidious when it comes to an oil change, every 8,000 to 10,000 mile and I only use Castrol Edge Titanium 0w30 - I know this might send the internet into melt down...  but this is just my experience, I used Castrol since I was 21 and I blew a Peugeot 205 GTi running running Mobil Super. Anyway.. it's another story. |
The "infamous" inlet swirl flaps were never fitted to any E53, as far as I can tell. Never found any evidence of an E53 with them (and I've looked a LOT). They were fitted to a lot of M57TU engine in other models, inc. the E83 X3 but never the E53 for some reason.
DPF seems to be rare (at least, from the factory). A few folk have fitted the retro DPF kit from BMW, in order to pass local emission laws etc. (Germany?).
The engine breather with the loo roll filter was factory fitted to all M57TU engines until around mid-2005, when BMW changed the production line to the vortex design. This is the same time as they released a TSB/TIB indicating the need to service (i.e. replace) the (loo roll) breather about every 60,000km. Seems they wanted to reduce service intervals (costs) and turbo failures under warranty.
The loo roll is a better filter, no question. The vortex unit requires less servicing, no question. Long term, I think the vortex design will lead to more inlet fouling but only time will tell. Ideally, I'd use the loo roll unit but change it regularly. It costs NZ$170 here though.. ouch.
Both design are designed to trap oil vapour precipitate and allow it to run back down into the engine.
Where did you get your refurbished GT2260V from?
