For What Its Worth
Motor Mount Notes
All motor mounts are not created equal. It seems funny that
something so simple as a motor mount could go so wrong. Just like
a house, when the foundation has problem, everything else has the
problem. The first picture is of the "Stock" replacement motor mounts I
first obtained from a local parts house.
They were both the same part number, but as you look at them you can
see differences. The one on the right was modified by
welding on washers to make it similar width to the one on the
left. They did not align the engine well and the one with
the washers welded on still fit the mount sloppy. I had to add
washers between the mount and engine on one side to get the headers to
clear the spring towers. It appears some hack believed they were
an engineer and could redesign one motor mount style to match the
other. Close does not count when conforming to tolerances and
specifications. When I had the chance, I got rid of them and replaced
them with Energy Suspension brand of motor mounts.
Picks of the good motor mounts in the car.
The difference was very clear. With the good mounts bolted to the
engine, motor dropped right on to the mounts, no problem putting in the
cross bolts. Headers fit well, no clearance problems.
Why did I use the cheap mounts to begin with? This was as the
start of working on the hobby car. I remembered always getting
good parts from a reputable parts house when I was a mechanic too many
years before. I was buying them from a reputable parts house and
assumed they were to "spec". I have learned the influx of cheap
parts along with the lack of car knowledge by many working in parts
houses now puts more responsibility on the customer for finding
and accepting good parts. My advice, if the part looks cheap or
in any way it could be a problem, refuse it. It takes two
groups to make junky parts. Those that
want to make a cheap profit and customers that think saving a dollar or
two is more important than a well functioning part.
