Oil drip from pressure sender - K series

[AndrewE]

Hi 

I have noticed oil is dripping from the oil pressure sender on my K series. The drips seem to be coming from the larger end cap where this end cap is sealed to the main body of the sender. There is no oil on the outside of the largest part so I must assume it is coming from within the sender - see pic

 

I assume this means a new sender but has anyone seen this before?

 

(and no I don't want messages about changing to mechanical sender thanks)

Well, I had a K for nine years and I never had a leak like that!  Mind you, I had to replace the sender every two years or so due to failure (erratic readings).

To be absolutely sure where the oil is coming from, clean the sender and filter housing thoroughly, and then get someone to start the engine while you observe from underneath.

If it leaks again the way you describe, a new sender is likely to be the only solution.

Haven't got an oil leak on my K series but I have got erratic readings and want to replace the sender. As usual Caterham are out of stock, anyone know what make it is and where I can source another?

Best of luck with oil leak.

Is that out of stock on the web site or really out of stock? Try Redline.

I have given up bothering to replace them, replaced one when I got the car, within a few weeks the same again, put another in and within a couple of days same again, waste of time.

You know the answer Alan. Cheaper and far more reliable !

Didn't the one you ordered earlier work?

I know that Ian, as I mentioned before I did not want to do the change whilst under warranty, might not need it if I change the car lol.

In which case, you might want to consider remounting the sender remotely.  There's a discussion here, and a list of parts required here (just ignore the last two on the list -- MOPG gauge and line).  This list includes the parts needed for an optional low-pressure warning light.
