Repair Mistakes & Blunders
a teenager, my interest in cars started
early, but doing maintenance and repair
was rather difficult, since I lived
in Manhattan, New York. With no garage
and alternate side of the street parking,
even washing a car was a chore, since
my family lived in a fourth floor
apartment. This was about 1970, and
a friend had just returned from California
with a nice, big white 1958 Cadillac
Sedan, with a powerful V8, which had
plenty of passing power. He loved
showing off its power and soon broke
a connecting rod. Surprisingly, the
motor still worked, but barely limped
He soon found a used
motor and a street that had no parking
restrictions, and asked me if I would
give him a hand in swapping the motor.
Easy job, he said, lots of room to
turn wrenches, and he had all the
tools from another friend. I jumped
at the opportunity to help and learn,
and on a hot July Saturday we started.
Out came the original motor, and by
late afternoon, the used motor was
in. Covered to my shoulders with black
grease and sweating quite a bit, we
hooked up the battery and hit the
starter. But the V8 would not turn
over. The tool guy suggested pulling
a plug to see what's up. As my friend
removed the plug, out gushed rusty
water, and our hopes for a running
car went down the street curb, along
with the oily water. The junk yard
motor had never been properly protected
The department of
sanitation picked up the abandoned
Caddy a few weeks later. The grease
on my arms had finally washed off,
and we learned a lot from that experience.
Never assume! Diagnose and test. It
saves much work and money.

Where is the Oil Filter?
is the oil filter?” asked the
man next to me at the car show as
we gazed under the hood of a new Chrysler.
There it was right on top of the engine
but hidden under a black plastic oil
filter cover. That Chrysler 3.6L V6
and many other new engines displayed
at the show use a disposable oil filter
cartridge installed inside a permanent
housing rather than a conventional
completely disposable, metal-housed
oil filter. The disposable oil filter
cartridge is one of those new, green
automotive features that are really
not new at all. Just open the hood
of a 50 year old GM vehicle to find
an oil filter cartridge.
Here are some slightly
edited tips from filter manufacturer
Fram for changing modern oil filter
- If the oil filter
housing is located above the oil
pan, then take out the filter cartridge
before draining the oil pan. Once
the cartridge is removed any dirty
oil retained in the housing will
drain to the oil pan.
- Replace the O
ring on the oil filter cover and
lubricate it with new oil. Many
replacement oil filter cartridges
include a new O ring.
- Do not use the
adjustable strap type oil filter
wrench you use on conventional metal
oil filters. The plastic oil filter
cover is more likely to last if
you use a Filter Socket type wrench
that securely fits the oil filter
cover. Under “Extras”
RockAuto carries oil filter socket
wrenches, adjustable filter socket
wrenches and sets of filter socket
- Watch how the
old filter cartridge comes out of
the housing. Some oil filter cartridges
snap into the oil filter cover,
some have a tube that needs to fit
into a hole, etc.
- Some replacement
oil filter cartridges are permanently
mounted into a disposable oil filter
cover. But do not throw away the
vehicle’s original oil filter
cover because you may need it the
next time you or your mechanic replaces
the oil filter cartridge with a
different brand or part number filter.
RockAuto does have replacement oil
filter covers for some engines if
yours is lost or broken.
In any newer car
it is especially wise to use the weight
and type of oil recommended by the
engine manufacturer. Sometimes it
might be tempting to dismiss the need
for a certain weight (5W20, etc.)
or expensive synthetic oil and just
use some of that 10W30 that works
great in your 25 year old truck, but
that is a bad idea. New engines not
only have tighter tolerances, longer
oil replacement intervals, etc, but
the oil might also be doing hydraulic
duties it never needed to do in older
Variable Valve Timing (VVT) and/or
cylinder deactivation might have solenoids
and valves that use motor oil like
hydraulic fluid. Using the wrong motor
oil might clog or otherwise disable
those VVT parts. For example, RockAuto
sells new Dorman Variable Timing Solenoids
for GM’s “Atlas”
4, 5 and 6 cylinder engines with VVT.
The solenoid fails when “sludge
buildup on screens and orifices hinders
oil flow, resulting in drivability
issues.” Using the wrong weight
oil, mixing weights or not changing
the oil frequently enough for driving
conditions can contribute to the creation
of that sludge.

is my 1972 Lincoln Continental. It
was originally from Montana, but now
resides in Canada.
At RockAuto I was
able to get a distributor, master
cylinder, shocks, brake and front
end parts. Plus some specific items
that I could find no where else such
as a fuel vapor emissions hose, a
blower relay, an air cleaner vacuum
motor, and an oil pressure sensor.
Thanks to RockAuto
I can cruise all summer long knowing
my car is safe and reliable.
