Oil change today...
Slight delay after realising that my 12mm hex key for the sump drain plug was in my tool chest stolen last year - so after a quick trip to the local parts store it was a relatively easy job :-)
Also added a oil pressure sensor and gauge to replace the cloudy clock.
Link to some excellent directions from an flu site at the foot of this post.
Only difference being the grey wire on my gauge goes to a grey wire on the tachy as I don't have a grey/yellow wire.
Also wondered why the instructions tell you to move the oil warning light sender to the front port.
Turns out because of the size of the pressure sender it just wouldn't fit there so they need to be swapped...http://flumichigan.italiancarclub.com/TechArticles/addinganoilpressuregauge.pdf
