Catalytic converter gasket

Showing 4 out of 4 Posts
Question From mercuryman on Catalytic converter gasket

I have a loud 1996 Mercury Grand Marquis. I eliminated the Catalytic converter on passenger side, but the connection is very loose where the front meets the manifold.

Do I cut 2 bolts, and replace gasket, and 2 new bolts
for repair . Do I need to remove tire, and is it easy to get at?

Response From Hammer Time

Eliminating converters is illegal.

What you do to resolve your issue is you drive it to an exhaust specialty shop that is equipped to have the repair and has the replacement parts and you hand him your credit card.

Fireworks are illegal too, but the whole neighbor hood is setting them off.
I am getting rid of the car in September. I already eliminated the cc, and I know its illegal. I am asking a question about removing, and replacing bolts, not whats illegal.
Reply with the answer like you have in the past. Don't be laying down the law like your Steven Seagal.

Response From Hammer Time

No problem. You don't like my answer? Why don't you go ask someone else?

Judging by the nonsense you have been asking here, you don't have a prayer of fixing this yourself anyway.

97' Mercury Tracer - Dies after starting

Question From scottcfr on 97' Mercury Tracer - Dies after starting

When I start my car, if I don't put it in gear and drive it immediately it will die. I think it could be the o2 sensor, or the catalytic converter. But, I'm no mechanic.

Response From Tom Greenleaf Top Rated Answer

Can you get codes read which would help. Guessing and tossing parts will just get expensive and a waste,

Response From Discretesignals

Where would I get that done? Just any mechanic shop?

'96 Tracer Trio Catalytic converter and rear brake issues.

Question From Guest on '96 Tracer Trio Catalytic converter and rear brake issues.

Ok I have a '96 Mercury Tracer Trio with a 1.9L 4 cylinder manual transmission with about 160,000 miles on it. I have 2 questions regarding this car.

Question 1) My rear brakes/emergency brake has been sticking on my car...I had a mechanic change the rear brakes at his house and when he went to put the new ones on he could not get them in...he said that the emergency brake was sticking...what parts are needed to repair the rear brakes/sticking emergency brake?

Question 2) Can anyone tell me the easiest way to remove a catalytic converter from this car being a front mount converter? I cant drive the car as its not running and I think the catalytic converter is clogged and need to replace it...but dont know how to get it off seeing as i cant get to the bolts on the top half of the converter. Please if you can tell me how to get it off and if possible a diagram would be nice.

Thanks...i really need to get this stuff fixed.

Response From Loren Champlain Sr

Heart; This is just a guess, but...As the rear brake shoes wear, and if not properly adjusted, the emergency brake will at some point no longer hold. Someone may have adjusted the ebrake to 'take up the slack'. If this is the case, you'll need to de-adjust the ebrake, replace the rear shoes, adjust them properly, then re-adjust the ebrake if needed. E brake cables can, and do, rust inside the cable housing, especially if this in an automatic transmission and the ebrake isn't used everyday. If this is the case, you can try spraying the cable housing with penetrant, but to be honest is usually futile, and may end up having to replace the cable(s). With this said, I'm assuming that you have drum brakes in the rear. If you have disc brakes in the rear, the pistons must be turned clockwise and depressed at the same time. (there is a special tool made for this procedure).
As far as the catalytic converter goes, I've never seen one plugged so badly that it would keep the engine from starting. Severe loss of power, yes. You can't 'just remove it'. If it's plugged, and I'd want to be darned sure, you'll have to replace it.

Response From Guest

Well the catalytic converter isnt the reason its not running exactly...it will start and everything but because it is plugged up it blew out the 3rd cylinder spark plug to relieve the pressue so i have to get a heli coil to put a new plug in to start it. I was wondering if anyone had a diagram or could explain the easiest way to get to the bolts on the catalytic converter to remove it that way i can check it. Thanks

Response From Loren Champlain Sr

Heart; I seriously doubt that the plug 'blowing out' is the fault of the cat. But, it sounds like you are determined to find out.. You can remove the oxygen sensor from the exhaust which will relieve any backpressure. It will be noisy, but will answer your question. Leave the sensor plugged into it's electrical connector. You may still cause a check engine light and trouble code. If it runs will full power with the sensor out, you are probably right. You can also check for excessive backpressure with a vacuum guage. Connect a vacuum guage to a manifold vacuum source. Take a reading at idle, then raise the rpm to 2500 and take another reading. The vacuum at 2500 should be as great, or greater than it was at idle. If lower, then you have a restricted exhaust. A better test is a pressure guage that you can connect to the exhaust where the oxygen sensor was. Any reading above 2psi is not good. (restricted exhaust).
There may be a heat shield covering the bolts holding the cat. to the exhaust manifold. If you remove it, you should be able to see, or feel, the bolts holding it.

Response From Guest Top Rated Answer

i can see the bolts but i cant get to them due to the small space around the cat. i dont know if anyone has any experience with this car or not to tell the easiest way.

Response From Sidom

My best suggestion is to listen to Loren, he is telling 2 of the best ways to test a cat/exhaust system.

1996 Mercury Cataylic converter rattle

Question From mercuryman on 1996 Mercury Cataylic converter rattle

I have a 1996 Mercury Grand Marquis, and replaced the cataylic converter last summer. It has a loud rattle noise.It is NOT a heat shield.

I read a post about drilling a hole in it? Sounds crazy to ruin a fairly new cc.
I also noticed the adapter cable is broken off the screw on the side of the converter. Would that have anything to do with it making noise?

Response From Hammer Time

Does the Catalyst rattle if you hit it with the heel of your hand?

Yes the Catalyst rattled with the car off, and hit it with my hand.

Response From Hammer Time

So, it needs to be replaced. The substrate is broken.

If it was replaced last summer, it should be under warranty.

Not sure what you mean here.

There is a light green wire with plug-in adapter that has a silver jack plug in on the end that goes into the nut on the side of the cataylic converter. It is broken on the end that goes into CC.

Response From Discretesignals

Does it look like this?

Does it look like this?




Yes that's it.

Response From Discretesignals

That is the oxygen sensor. Your check engine light must be on.

If the front 02 sensor isn't working, that could damage your catalyst. The computer needs the signal from the front O2 sensor to be able to trim the fuel to air ratio for proper converter operation.

How long has it been like that?

Not sure. I had no reason to go under the car except for oil change, cause the car has not had any trouble since August of last year. I took out the bulb from the dash, so I would not see any check engine light over 3 years ago.

Response From Discretesignals Top Rated Answer

You'll probably need to replace the damaged O2 sensor. Then you will probably need another catalytic converter because it may have gotten toasted. Then it would be important to clear the trouble codes from the PCM and then see if any come back.

Response From mercuryman

OK I will replace the sensor, and see what else I can do to quiet the car down. 280,000 miles, and it was so quiet until the cat converter starting screaming.

Response From Discretesignals

If you replace just the sensor and the catalyst substrate has come apart or melted, you really don't want to be putting a new sensor in that environment.

That reminds me of an episode of The Simpons where Homer's piece of black electrical tape that he put over the check engine light fell off. He said "whoops", put it back on and said something like, "who needs a mechanic, the car is good as new again".


Now if they put something like that in a cartoon comedy it proves how idiotic it is to ignore and even go as far as to take the bulb out or cover the light with electrical tape. When the check engine light is on your car is telling you that something is wrong. Many times, if ignored, it will end up costing you more money in the long run. If one thing is malfunctioning it could cause other issues and even possible engine damage.

I'm really surprised you bit your tongue HT! You too DS! Normally you guys would be all over something like that.

Response From Hammer Time

I'm really surprised you bit your tongue HT!

You can see what we're dealing with here. I'm concluding the whole effort is just a waste.

Response From MarineGrunt

I am really surprised HT didn't fire up his flame thrower though...lol

lol.....I can only imagine what words of wisdom he had going through his head. You know he instantly had his fingers on the keyboard ready to fire away and at the last second said the heck with it.

You know, by the time he tore the cluster out and pulled the bulb it probably would've been easier and quicker to get the codes scanned and replace a faulty part.

Response From Discretesignals

For all we know he could of drilled a hole through the cluster faceplate and ripped the bulb out with a pair of needlenose.

Response From nickwarner

You mean there's another way to do that? Boy now I feel dumb.

Response From Hammer Time

I can do it through the tailpipe.

Response From Discretesignals

Please tell me you don't do that with your lips or something along those lines...

Response From Hammer Time

Haven't you ever had a colonoscopy?

Response From Discretesignals

Not yet, but I am sure i'll be getting them in my life time though. You know it is bad when your getting a prostrate exam and you see both hands on your shoulders.

Response From Discretesignals

I thought about it MG, but why even bother. If the owner doesn't want to figure out or fix the problem that is causing the light to come on and wants to disconnect it, that is their problem not mine.

If you think the noise is your only problem, then just turn the radio up. The noise isn't the issue here. The broken catalyst is.

I'm gonna bite my tongue.........................

Response From Discretesignals

I did the same thing. I knew it would be useless to even go down that road.

Response From mercuryman

hi Hammer
I will go out in a while, and try that. Post again shortly. Thanks.
