Yee Hah.
Well I worked on the Mars-tt all day. What a
wonderful day.
I installed my Mocal oil cooler finally which led
me to start pondering.
Q1. After driving it VERY hard for 1/2-hour or so the temp never went over 180
deg. It used to vary between 200 and 210deg. most of the time. I use
Redline 20W50 Synthetic. Is it possible to run the engine too cold, or
not hot enough. The sandwich plate has a thermostat in it and appears to be
working correctly.
Q2 I noticed that when I pulled
off the oil filter, the Synthetic oil was a med. brown. The engine now has
about 8K miles on it and the oil has about 2K on it. Is this normal, I kinda
figured it would still be fairly golden colored. Would this darkening be due to
overheating the synthetic, running too rich a fuel mixture, ???
Q3 When I put the cooler on it was dry
(no oil). My assumption was that when the engine heated up it would flow through
the cooler and at that point the engine would slowly lose oil pressure and end
up low on oil. I ran the motor until I felt the cooler lines get hot. Then I let
her run for another 30 sec. or so and shut her down.
I then put another qt. of redline in and checked
the level. It was right at full 8) exactly as I had expected. I was
wondering though if you can get air in the system and cause a pressure problem
or does it take care of itself. (my oil pressure gauge isn't working and I
haven't replaced it yet so I don't know what the pressure is at)
I also managed to:
Install my freshly painted radiator fan shroud,
fan, and alternator.
Installed all the Non-AC pulleys and
now my new belt lines up perfectly with the
crank, WP and alt. I couldn't believe how much wt. I shaved by doing this. The
AC dual crank pulley setup uses a thick steel pulley, another piece with 4
studs, half dozen steel shims and two pulley halves. Non ac just uses a
lightweight sheetmetal pulley. I must have taken off 3-5 lbs. of rotating wt.
Kinda like lightening the flywheel but on the other end of the crank.
8)
Cleaned, waxed and put my un-cracked OEM "S"
spoiler back on the car.
Cleaned my "black" revolutions (wow they are
silver, almost forgot).
Cleaned and waxed the original paint.
I just had to stand back with pride when I was
finished....sniff, sniff (wiping the a tear from my eye). They just don't make
cars with this kind of classic beauty anymore. It is days like this that make me
realize that I will probably own this car till I die. Just thought I'd
share. :)
Thanks for any advise on the above
questions.
Keep on Scirokn!
