Re: Damaged SOMETHING with backfiring ...

Well, I finally got my catalytic converter all the way off. I had to cut the
screws off with a dremel. Anyway, it's completely hollow. I'm not sure if
it's supposed to be like that. My concern is that the backfires blew some of
the "guts" of the CC down the pipe and possibly cause a clog there or in the
muffler.
Any thoughts?
Also, when I replaced the hall sender, I used an old one from my other
rabbit. I assume it's working fine since the car runs without cutting out
now (unlike before I replaced it). As far as I know, hall senders just send
a signal to the coil and it either works or it doesn't. That is, it can't
send a "weak" signal. But I just wanted to make sure that I didn't overlook
something or use an inferior part. Again, any thoughts would be greatly
appreciated!!!

Good now you can proceed to other issues like ignition, fuel exhaust, etc
since the engine passes the comp test..
Yes replace any known bad component to eliminate that as a possibility.
You have identified that #2 noise as an exhaust manifold/gasket leak.
Fix that if the tick is annoying or very loud.

And you think the loss of power is due to a clogged cat???
There are inexpensive "universal" cats out there or you can temporarily
install a test pipe on the exhaust in place of the cat. I vote you
install
a bolt on cat and be done, unless you are not sure about having a bad cat.

Compression test results:
I removed all plugs, put the pedal to the metal and cranked the engine.
The
results were nearly identical for each cylinder.
First crank was roughly 95-100 PSI for each cyl.
After about 5 cranks, the guage leveled out around 175-180 PSI. I doubt
there was more than 5 PSI difference at any stage across the board.
I'm assuming this means my engine is okay. At least by this measure.
However, I am still operating with the rear half of the exhaust system
removed (catalytic converter and tailpipe disconnected). As is, I have
seen
some smoke when I rev up the engine. Is this a sign of another problem,
or
is this to be expected when the converter is removed?


PS -- I have not replaced the plugs, but I have replaced cap, rotor and
wires. One
of the towers on my newish rotor already had some damage -- pretty heavy
carbon deposits, and what appear to be a slightly displaced inner metal
sleeve
