[Vwdiesel] Oil Light/Buzzer

[Sandy Cameron]

Didn't realize what a rant I would cause by using: Canadian Tire full synth
5w50 in my 87 jetta with TDengine from 82 jetta (modified engine mount),
450,000 km on car, at least 100,000 on engine by me, who knows how much in
the 82.

I tried the 5w50 last winter, and it improved the cold starting so much, I
use it from end of November to end of march, then go back to 15w40 for the
summer.

Only time buzzard sounds is long upgrades hauling the snowmobile on the trailer.
Hard work for an A1 TD engine in an A2 car. Temp rises significantly too.

This engine uses zero oil between changes, passed smog test flying, starts
at -25C (-3F) without help, up at my camp, where the snowmobiles struggle.
Best thing, oil pr. light goes out immediately as oil circulates instantly.
WORKS FOR ME!

In past, using heavy ordinary oils, oil pr. light might not come on for 30
seconds. Scarey. I sometimes wonder if the back of the timing belt was
slipping on the aux shaft pulley until the oil pump started to turn in the
tar-like oil.

This to Hagar the Horrible,,, I'm an old fart too, 69, grumpy old man, doing
another engine transplant in another '87 "gift horse" (Converting a gasser
to diesel)
Will report on how the legalities go.

During the second world war (!) a Canadian air mechanic developed the oil
dilution system for cold starting of aircraft piston engines in arctic weather.
Before this, oil had to be drained at shutdown, and heated by a blowpot
heater  and dumped back in the engine before starting again.
I'm sure Hagar will remember this and long underware too.

At shutdown, a valve was opened by the pilot, that allowed gasoline to enter
the crankcase, diuting the oil, while the engine idled, circulating it
through the engine's lubrication galaries. the engine then was stopped,
covered for the night, and the next morning started without trouble. While
warming up, before take-off, the gasoline was evaporated from the oil by
engine heat, restoring it's normal viscosity (displayed as an increase to
normal oil pressure)
The rise to normal oil pressure was the pilot's cue that it was ok to take off.
The US army and airforce adopted this big time. Take a look in the cockpits
of some old arctic war birds, and you will see the valves. Most often fitted
to the harvard trainer  (Called the TEXAN south of the border}

Now I know there will be armchair mechanics out there who will cry foul,
scream about exploding engines, run bearings, etc, but none of that
happened. The gasoline evaporated slowly over 20 minutes or so during
warm-up, in the crankcase where there is no fire to ignite it, and probably
never came close to a stochiometric mixture anyway. Blew out through the
crankcase breather and became air polution.
