Re: Timing belts and band saws...

Yes, I had this problem when I first bought my 16v.  The only way to 
keep the piece of sheetmetal from rubbing is to cut out the part of the 
shield that is rubbing or replace the whole shield with a new one.  I 
cut the shield that's in there.  Someday I'll probably put in a new 
shield, but this has worked for now.

My pass. side motor mount is in the 88 and running. Just in time...the
brakes on my 87 decided to disappear on me while approaching a stop 
sign. I
haven't had time to look at it yet, so there may be some questions 
coming
soon!

Since I needed to be in Madison, WI this weekend, the weather was nice, 
and
the salt was almost completely off the roads, I made a call to the 
insurance
company to see if I could drive the 88 instead of my GF's 91 Hyundai. 
It's
an OK car for basic transportation, but it recently developed a loud
exhaust, and a 4hr. trip just didn't sound like fun...

We finally get to the issue: It appears (note that's not a 100% 
sureness!)
that my timing belt is rubbing on that thin piece of sheetmetal behind 
it on
the long side between the intermediate shaft and the cam pulley (16v, 
BTW).
When I first reassembeled the belts after changing the motor mount, it 
made
a high-pitch screech noise, almost like a band saw when you cut wood. I
pulled off all the pulleys and belts again (ugh...) and reassembeled. It 
was
then that I realized it seems to be this sheetmetal piece. I played with
moving it various directions. It only goes about 1mm any direction on 
it's
bolts, which are also 2 of the bolts for the motor mount. I also played 
with
varying the tension on the belt a little. I got it so that it almost 
never
makes noise, but every now-and-then still does it. It's MUCH quieter 
now.
You have to have the hood open to hear it. It bothers me that it does it 
at
all, 'cause I don't think it ever did before. It made it over 400 
beautiful
and quiet (new motor mounts rock!) miles this weekend, and though I 
popped
the hood numerous times, I only heard the noise once. It does seem to be
that sheetmetal piece, cause pushing on the flange behind the belt while 
the
engine's running (not something I would normally do...I used a 
screwdriver
handle) will start/stop the noise, but I still am not entirely sure.

Any 16v-ers have this experience? What did you do?
