i have to agree with mark here. there is not much that can compete with
parts were built for the auto companies while the vehicle was still in
production. having been in and out of thousands of parts plants here in
the detroit area i can tell you that small shops will never put out a
product with specs as tight as those parts originally had. the problem is
not the desire to produce a nice high quality product but rather the
barrier is the tooling cost.
IMHO you can't really make a "production" part without a CMM (computerized
measuring machine). CMM rooms cost hundreds of thousands of dollars to
millions of dollars. most of the oem plants that i have been in 100%
parts, that is that every part is 100% inspected. that is one of the
reasons between the cost of identical looking parts with the vw label
scrapped off. that 100% check costs a lot of money both in measuring
tooling and labor costs. thats why the manufacture "generally" doesn't
want their name on it because anything you don't 100% is going to have a
overall lower quality reputation.
add to that trying to rework cores that have twisted dimensionally and
using production machines and tooling past their prime and you get parts
that aren't as good out of the box and don't hold up as well over time.
often substandard parts are made in the same oem plant that made the part
originally. i have worked on these lines, the shove old worn machines and
tooling in the back of the plant or in a corner. then to cut cost they
cut quality control and don't test measuring equipment. to further cut
cost when a part comes out that doesn't meet spec those few times that you
do actually measure it you just run it back through the machine until its
close enough or the operator is tired of looking at it. i have see lines
and talked to operators where there is a maximum of scrap allowed on that
line. that means that if they have already meet the scrap quantity for the
day they WILL ship defects, and you will lose your job if you don't put
the defects in the box. this takes place in oem plants with oem tooling
and these parts are sold under the oem suppliers name!
the same really applies for the installation of parts and assemblies. i
am often very turned off at some of the repair work that i see people do
and turn out. but alas most weekend wrenchers and a LOT of professional
mechanics don't know how to measure and analyize systems. nor can they
see clear to spend the money on tooling to do so. they are just
part changers and in general feel better about themselves and their job as
a function of the new shiney parts used in the process. i guess i will
sum it up with a line i recently read on a vanagon persons web page. on
the page the individual was working on their transmission and in the
process of the work cycle decided to paint the transmission. the person
just painted over the half cleaned transmission with silver paint and the
proud caption below the picture said the following. "who says that pigs
don't look better in lipstick".
