Help Indentify Random pipe

Hi Guys, Not been online for a while due to work commitments, but I finally found some time to fit my erg blanking pipe today, wow the amount of crud in the inlet was crazy, anyway I had a check around everything under the engine bay at the same time and found a pipe round the back of the engine block that seems like it should be connected to something. Does anyone have any ideas what this could be and what it should be connected too?

As you can see there is a plastic connector on the end that looks to have been broken away but I cannot see what it would connect to.

Turbo vent filter, the filter is missing. Do a search on ebay and get on fitted ASAP.

Wow that was quick S1monm thanks, I will see if the eurocar parts have one and pop down during the day. looking online there is 2 sides to the filter, should the other end be connected to another pipe?

if they do not have one a in line petrol filter would do the one you have on at the moment is not original and it just hangs there some had a small piece of pipe on the other end so it would go into a clip

As per teddy, just vents to atmosphere

Thanks again guys, such a wealth of knowledge on here.

Other question sortoff related (but no pics yet) on the l series near the turbo area theres some pipes that are just moulded with a stop end and somewhat U shaped and basically go nowhere what are these for? I thjnk there standard someone else mentioned them on here also possibly in one of the egr threads..
