My 2008 RR sport has a small air leak coming from the blue collar pipe on the front of the air compressor. The air is actually leaking from the blue collar location. Can you simply fit a new pipe and collar or is the blue collar an integral part of the compressor? Or is there a product on the market I can use to seal this small leak?

Advice would really be appreciated. Thank you in advance.

maybe time for one of these, as the lids crack.

It might be, but I'm pretty sure its just the pipe that's leaking and not the blue collared socket itself.
Somebody out there must just sell the shaped piece of pipe?

Sorry I didn't think you wanted the pipe.

It will be the cap, or o-ring inside the collar

Never, ever seen the rigid plastic pipe leak

The full story is that a few weeks ago I hit a pot hole and in a moment of madness at the side of the road I jacked the car up inserting the jack in the hole on the compressor cover rather than the chassis. This in turn broke the compressor bracket. I managed to change the bracket without removing the compressor but for a while the car was used with the compressor hanging from the pipes only as the bracket was snapped in two. This caused stress on the pipes which is why I assume it is the pipe that is damaged and not the collar. Can you buy just the pipe from anywhere.

That pipe is quite robust.

Thanks everybody for your appreciated advice. I shall further investigate this coming weekend.

OK I am now lost. I have fitted two new plastic pipes to the pump, the metal drier end cover as recommended earlier ion this thread and still after a week my RRS looks like a low rider. All 4 corners lower fully within a week. I can no longer find any leaks but obviously there is still one somewhere.
If I drive the car daily the compressor comes on for 60 secs or so after parking up. The leak must be around the drier/pump area as all was fine until my idiotic roadside error but I simply cant see any leaks.
All advice truly welcome as I am now out of ideas.

Air tank wouldn't cause the car to lower overnight. You have a leaking air bag

It all started when I jacked the car up and broke the compressor bracket. The pump hung loose for a week or so by the plastic pipes. It is too much of a coincidence to not be related to this incident. It doesn't go down overnight it takes about a week of no use before it settles to low rider stance.
The compressor has 2 plastic pipes both of which I have replaced and 2 metal pipes which show no signs of damage or leaks. The car definitely has a small leak somewhere but I just cant find it.

What about the valve next to the compressor

Is that where the other end of the plastic pipes go. If so I have sprayed them with leak detector but it is hard to see the complete 360 degrees. Certainly worth a closer inspection.
Thanks Ill have a look this weekend
