I recently installed the GWesty oil relief drain plug with GWesty temp
sender and hooked it up to an Intellitronix digital gauge. Through my lack
of knowledge, I discovered that I should have used the proper sender that
came with the gauge as I am getting some fairly odd gauge readings based on
the relationship between the gauge and the sender.  I had thought these
things were relatively universal - but supposedly they are not.

Anyway I plan to swap out senders but would like to know how much oil will
drain out from the open relief port...pretty much the whole 4 to 4.5
litres? or just a portion of that amount?  Please advise.

As well I bought an oil pressure switch relocation kit from Mansispeed and
have it hooked to an Intellitronix  pressure sender and digital pressure
gauge.  The kit moves the low pressure switch from between #3 & 4 cylinders
up to the top of the motor and near the t-stat.   I should be getting
pressures of 2 to 5 psi however I am seeing readings of 60 on start up and
then drops as the motor warms up to 25 to 30 psi.  Wondering whether this
is a product of the sender or its placement - or just how the gauge reads?

Lastly - any tips on stopping oil from lightly sweating / leaking from the
threads of the pressure gauge fittings?  Supposedly - not supposed to use
plumber's tape as it could affect the grounding and I have tightened the
fittings pretty snug - don't want to horse it much more.

Thanks,

BT
