Bearing noise. Pop the distributor cap and see if you can wiggle
the rotor side to side. There should be no slop. There should also
be no oil in the bottom. A failing bushing in the distributor can
cause this noise.

That's some screwy plastic to work with. Forget the glue gun, it won't stick.
A hot nail might work. So could some epoxy made for the plastic. Look
on the bottle for the type of plastic it's made of. Little triangle thing
with a number usually. Then get an epoxy for that type of plastic.

(By the way, there was a recall for leaking accumulator in that model
year. Check to see if the recall was done, it might be a free fix
from the dealer)

Won't work. You need the antenna mast from the dealer or opt for an
aftermarket rubber antenna.
If I can find the part number I'll post a followup.
By the way, the motor is a pain in the *** to get at.

Nope. This can happen if the door switches or hood switch get contaminated
with salt. The salt provides just enough current to set off the alarm sensor.
Start with the hood switch. It's down on the passenger side. Just pull the
wire off and put some tape over it.

I went aftermarket with power windows, starter, and 300ft range remote.

Been there done that, still not evident precisely where it comes from-- but,
it does seem as though it is slightly more apparent from underneath, by the
oil pan.

I bought this epoxy at autozone, I believe it's called "Steel Weld" or
something like that (don't have it in front of me now). It says it does
plastics, and also specifically mentions antifreeze in its' "Liquid
resistance" section.. none of the others I looked at mentioned this so Im
gonna try with that.

Can that be done without dropping the trans case? I know it's kind of hard to
get at, but it doesn't seem impossible.

Interesting, since it comes up in AutoZone's computer for 96 JGC 5.2 as a

Re: 93 GCL ZJ: Low idle, engine noise +other probs (long)
It looks as if you are trying to seal a plastic coolant reservoir tank. I
have had good luck sealing these with silicon sealer, aka RTV. Unless they
have improved epoxy since the last time I checked, it is not flexible enough
for this application. Good luck though. Whatever you use, a clean base
for the repair will be essential.

have had good luck sealing these with silicon sealer, aka RTV. Unless they
have improved epoxy since the last time I checked, it is not flexible enough
for this application. Good luck though. Whatever you use, a clean base
for the repair will be essential.

Re: 93 GCL ZJ: Low idle, engine noise +other probs (long)
It looks as if you are trying to seal a plastic coolant reservoir tank. I
have had good luck sealing these with silicon sealer, aka RTV. Unless they
have improved epoxy since the last time I checked, it is not flexible enough
for this application. Good luck though. Whatever you use, a clean base
for the repair will be essential.
