Hi all, Im new here but hope you can help me.
(2004 Fiesta 1.25 LX, 5 door)
I topped up my engine oil the other day and noticed a pipe (with 'eco' written on it) hanging loose from the engine. I plugged it back in and it hasnt fallen out since (a few weeks). it does not 'click' back in or anything but seems to be ok now. I'm worried some damaged could have been inflicted on my engine whilst the pipe was out however. I dont know how long it was out for either, could be anywhere between a week and a few months.
What is this mystery pipe? thanks in advance.
