Bees in a can

[Parademic]

Hey all, just a quick question before I hack my exhaust up tomorrow.

I've got this noise coming from under the car forsure. The entire exhaust looks really good and not rusty, but there is this loose change or bees in a can noise coming from under the car. Definitely around the cat / downpipe area.

just wondering if anyone else has run into this? I'm thinking the core in the cat is messed up or something like that?

Also, if I cut out the cat, I'm not going to have a spot to put my o2 sensor again. Obviously this will cause a check engine light, but it shouldn't cause any other issues correct?

I'm still not too used to German cars, more so the japs.

Loose heatshield.

Could be broken catalyst rattling around.

Loose heatshield.

I had a loose heat shield that was making a combination of VERY strange noises on my 8v.

also check if the O2 sensors are tight...

so if this was 'a jap', what would you do?

Lol... I've also seen the centre exhaust brackets rust through and cause rattles. Look at the centre hanger/bracket that cradles the exhaust.

I've heard of bukkake valves coming loose and rattling. Over time, they can start to spray fluid.

as Dac said, the problem may be complicated but I'm sure if you invite a bunch of friends over and circle the problem you could give each other a hand and cum to a solution.

I am unavailable.

wow....

The shop I work at has programs and flashes for most japanese cars. We do not carry really anything for German electrical. And if it was an obd1 car, obviously I would not have to ask about the check engine light.

Are there any rear o2 eliminator kits?

I will do a more thorough check on the heatshields. I removed one already, but I will go ahead and remove the other.

As for the mounts, the exhaust system on this car, including hangers look damn near brand new, really clear underneath. Rained in Courtice today, so I will have to get at it tomorrow.

I know one of the heatshields, further down the exhaust, feels a little loose, but I didn't think it could cause much issue. I'd prefer it to be that over having to cut out my cat and weld in a pipe temporarily.

oh, Japanese flashes for electrical noises. of course.

damn that german electrical. when will they invent compatible electricities?

I'll post this part of my original thread again, direct copy and paste, hopefully you understand it this time.

check the muffler bearing that mofo likes to rattle all the ****ing time on my car

First thing I checked was to make sure my halogen fluid was topped up, muffler bearings were second and then I checked the reverse transmission too. All good.

Another update is I removed all the heatshields that were close to the area where the noise is coming from (around the cat and that was one big ****ing heatshield), noise is still there, so I'm leaning towards the insides of the cat are messed. No real time at work to cut and reweld.

All you need to do is bang on the shell of the cat with the heel of your hand (or mallet if you're hand is fragile) and you'll be able to hear if the catalyst broken.

I'll do that tomorrow . The only other option could maybe be an exhaust leak, but nothing looks to be rusted through, or in bad shape. hmm.

bahahaha
co-workers giving me an odd look for laughing so hard all of a sudden

[ELup]

also check between the cat and resonator, there is a clamp bracket that is known for rotting. just replaced one yesterday on a golf i safetied. GL

[dubbreaker]

Too funny.

Don't forget to check clearances, my mk2 always had issues over the rear beam.
