Minor Repairs

OVERFLOW BOTTLE - Ever since the original cooling problems (2-3 yrs?) I have had an overflow bottle on my expansion bottle   I wanted to see if any water was coming out of the pressure cap on the expansion bottle.  While Andy and I were comparing engines at Baston I noticed it had fallen off.   It had only ever been jammed in the chassis so it wasn't totally surprising. 

So put a new one in (using the water bottle I took to Baston) but this time punched a couple of holes near the top and secured it with a cable tie.    Result:  Still there after the trip.


MEMS ANALYSER - As usual, I had plugged in my laptop to check the ECU on the journey to Baston but it just came up with an error message.   So this morning I checked the wire and found part of it broken where I had used a very tight cable tie.  So repaired that.  Result: it worked perfectly.  

Unlike the lambda sensor.  Still no idea what is going on.

FAN WARNING LIGHT - Since I rewired the system the warning light didn't come on.  It's rather a complex system as I have 3 ways the fan can be triggered (primary thermostatic switch in radiator (suspect), the secondary thermostatic switch in the top hose, and the fan override switch on the warning panel)

so I decided the simplest solution was wire the light in parallel with the fan, so regardless of how the fan is switched on the light will come on. The 'rats nest' gets worse, although at least I have labelled them this time   Result:   Works perfectly.   Dropped in at the garage on the way home and as I left the fan came on for 2 mins and the light came on.

TEMPERATURE GAUGE NOT WORKING - I pulled the connection to the temperature sensor and then put it back.   Result:  Worked perfectly, must have vibrated loose.

INSULATION - The clutch rattle was so bad with the new MDF cover that I decided I needed some sound insulation. 

Used a gash piece of carpet to do this.  And the MDF cover sits on top.    Result:   Much quieter so it serves it's purpose.  HOWEVER, the severe rattle & vibration at low speed is getting worse and worse.    I think either the propshaft or drive shafts are on the way out.    I think I better go underneath tomorrow just to make sure that everything is still tight and there are no loose bolts in the transmission.
