with all the talk about motor mounts recently I decided to
investigate mine. I noticed they were compressing and
sagging more than I thought they should be.
two years and less than 2500 miles ago I replaced the
original mounts with a set I got form my favorite west coast
seller. part number Co4794. listed as ENGINE MOUNTS, they
don’t offer a C18556 or uprated version anymore.
first a note about the bolt, or setscrew as they call it. my
original bolt fits fine, so does a new grade 8 bolt I
bought, both are standard thread, not metric.
I ordered a new set of the uprated version from Welsh and
began to swap them with the ‘‘old’’ mounts.
the uprated mounts are a lot taller than the original
design. I would be cautious if your bonnet is already close
to the top of your motor. You may also encounter throttle
linkage binding as I did, that meant another hour of
fiddling on something else too!!
I posted pics to my album of the old and new mounts.
if you have aftermarket mounts please look closely at them
after comparing my pictures.
you will notice in the picture of it in place the rubber is
visibly starting to crack and split under compression.
seemed like no big deal until I got it off. both had sagged
considerably but the right side mount had the threaded
portion delaminate from the rubber.
these are only TWO years old.
I don’t know what to suggest. but clearly these aftermarket
mounts are crap. and before you say, well they must be
bumper mounts, they sold them as engine mounts.
now they aren’t expensive, but the argument of buying from a
reputable seller has no merit, thats where these came from
and they are junk.
I am not blaming the seller, I buy a lot of parts from them
and I like their service. these are a cheap item, if they
cost me $100 each I would feel different. but I think its
important to watch your mounts if they are a new replacement
part from any seller. I am guessing they are coming from the
same worldwide distributor unless they are specifically made
or marked from a trusted source.
The Welsh uprated have a metal cone over the top of the
rubber, but there is still a stalk of rubber between that
and the base, looks like a potential weak point to me. Time
will tell. and of course there is no label as to country of
I hate to have to add motor mounts to my annual oil change
as a wear item. but it seems I might.
