Subject: IML: Voltage limiter question/ Crankcase Blow by
Date: Wed, 16 Aug 2006 20:54:34 -0400
If the Oil Pressure gauge is pegged, and the others are flat, that probably
means that the voltage limiter has siezed, burned out the Fuel and
Temperature, and is in the process of burning out the Oil Pressure gauge. I
would recommend that you obtain a working cluster, then fit the external
voltage limiter to the back of it. The limiter mounting point will act as
the ground. Then connect the power input to it instead of the Temperature
gauge power input. Provide power to the Temperature gauge and leave the
remaining jumpers to the other gauges as they are. There is discussion of
this on the OIC website. The cluster comes out through the front after
removing the bezel, phillips mounting screws, and wiring. You will need to
remove the wires one at a time after pulling the cluster. It will not pull
very far away from the panel until the wires are undone.
Smoke coming out of the dipstick tube of an otherwise good running engine
usually is due to crankcase blow-by. You might also check the draft tube to
see that it is clear, or if the car has been fitted with a PCV system, make
sure the vacuum line to the valve hasn't split. If the crankcase isn't
ventilated properly, the engine will be damaged in short order. If it is
ventilating, and just has excessive blow by, it should run fine for a long
time, but the smoke will probably bother you, your passengers, and cars
next to you in heavy traffic.
I suspect the car has an after market pcv system that has become disabled.
If so, it should be an easy fix.

hi, i am back from a hot rod weekend here in in the uk, whilst having
problems with failed gauges and high reading oil pressure- now smoke came a
wafting out of the indicator stalk hole on my 60 crown. ??? still works
mind. the car is a star and wish to keep it so ...
am using it for a wedding on saturday just hope she dont go up in flames
!!! how do you get to the cluster??? for limiter? should i just fit some
remote modern gauges and leave well alone ? back to the indicator smoke ,
wots all that about? also i have a power drain somewhere which leaves a low
glow on the handbrake on light. unable to locate source, so av bin removing
battery lead to prevent flat.
best wishes, steve.
