Newbie needs a bit of guidance, I have a 2001 tdci Focus, there is evidence at the back of the engine bay of a previous oil leak, and while the car hasn't lost a millimetre on the dipstick since last oil change 6 months ago, there is still a liberal coating of old oil around one area of the car. I decided on Saturday to get some degreaser and clear away the old unsighlty engine oil, but as I started, I wrapped the cloth around this pipe and gave it a good wipe from right to left and it snapped off in my hand. I'm no mechanic and don't even know what purpose this pipe/hose serves. The car starts and runs fine, no enigine warning lights etc. Can somebody please identify the little black box where the pipe starts, and what do I need to order to replace this. For reference it is about the same diameter as a drinking straw, approx 15 - 18 inches long. (Also, does anybody have a part number for the air intake hose just left of the lower yellow arrow, as you can see this has a badly repaired split where it turns into the egr valve).

Thanks very much.

It's the crankcase breather hose as far as I can tell.

It shold go from the connector to a carbon collector can of some sort.

If you find the 'can' (or plastic bottle) clean that out as it's most likely full of sludge.

Hi, the pipe that you are pointing to is the map sensor pipe, its a hard plastic pipe with soft rubber elbow ends, most good ford outlets will be able to get you one.

Hard to fix as its it made of hard plastic for a reason, so that it will not collapse under vacuum pressure.

Hi Alan, thanks very much for your response, I'll have a bit of a scour round for a replacement, in the meantime, what are the implications of driving whilst like this? and is there anything specific I need to know when fitting a replacement or is it just a straight swap 'plug n play' scenario.?

thanks in advance.

Jon.

Hi Jon

The car will not run well with the pipe off , you could take the rubber elbow off the egr, dig out the broken part from the elbow, and cut a very small piece off the hard plastic pipe, then try and join elbow to the hard pipe, take care when doing this as the hard pipe is fragile, to help you do this take the other end of the map sensor and do it in doors in the warm. it will work for short time giving you the time to get a new one.

The new one is a straight swap.
