Quick update (no photos, yesterday was one of the worst rainy days that I can remember...)
Decided against my better judgement to get out and sort the front out on the car and get a blanking plug into my sandwich plate (that was using the water sensor...) I got four blanks (good that I did). So raised the front up and lowered the car, tried it a few times to get the front lower then the rear, think I might have upset the pre-load of the spring on the BC coils on the front right, need to find out how to set that back up again). So after 3 attempts up/down wheel on/off I think I got a decent height on the front compared to rear. Did the other side (it's pretty straight forward on the BC to lower the fronts, release the bottom lock nut and off you got left ot lower and right to increase riding height. That was the easy part done, under had to get in under the car and replace the water sensor to a blanking nut had got four ones so happy days if I drop one or two while under there. First off to get the sensor off in the first place proved pretty hard, couldn't get to it properly to twist it around so had to use the wire's themselves to twist them around (once I got it loose enough) this then in turn put a turning pressure on the bolt... a good while later I had it out and a nice trickle of oil now started coming out . Took the blank and an allen key, tried at least 30 min to get it to thread while slowly turning the allen key... didn't work... (meanwhile it's bucketing down... getting rain in my ear channel while lying there trying to concentrate)... managed to get my 'master wrench' kit together that can use a bit with rapid action! god save halfrauds!
"Halfords Professional 33 piece Metric Ratchet Spanner Set" > so with this at hand I used that and put a finger at the nut to get the 'rapid action' working, slowly turned turned turned, finally go thread and it's on! wohoo! Then hear a 'click' sound while tightening it... sat there for 5 min considering what to do, out with the blank and looked at it, cracked took another one, dropped it 3rd one lucky... tightened it happy days it's there tight enough and didn't get wrecked then notice it's not flush fubared threads?! looked at it for another 5-10 min... different angles, finally relalised the plate itself is curved so it's "ok" that it's not flush against it stuck it all back an lead the wires for the oil sensor to the battery compartment, called it quits. Might go down the road of replacing the whole plate.
