I was too lazy to find the thread. But I found and ordered a copper gasket, I thought I would help out everyone. The price was $19 with shipping insurance.

Nice! If I still had my header I would be buying one of these in a millisecond.

Mind putting the site?

 

I just used a regular Fel-Pro crush gasket on my header down pipe....

What would be the advantage of this copper gasket instead?
Thanks

 

The advantage is that they won't blow out b/c they are solid metal. Whereas most other gaskets are two pieces of thin metal sandwiching gasket material.

 

I really need one of these but it looks like this gasket is not perfectly flat and has two ring-like gasket indentations on them like for the OEM header, will this still work for me? I have an aftermarket gasket that is completely flat so the rings will not work. Anyone know where a flat copper gasket is?

You know what dude, the more I think about that gasket that you were talking about and it's the same one I had before that gasket material will burn off in short time and will cause the oxygen sensor to go out. I would either get something similar to this that is solid metal or get a new header that will handle a crush type OEM gasket.

 

My 02 sensor is on the header so even if it burns off nothing will happen.

I ordered the Subaru gaskets from Advance and going to put those in and also I ordered that all metal one from ebay. I figured why not, its only 5$ with shipping.


I guess I already found out what I needed and even more thanks to the guys at Cb7Tuner.com. Thanks for your help too. Its interesting to see what other forums say.

 

there you go...feel free to report back your findings

 

Wrong. It won't cause the o2 sensor to burn out - it will simply cause a large enough exhaust leak that will cause the CEL to come on.....in addition to running poorly and getting terrible MPG. This is what happened when I had a had a garbage OBX header and the gasket blew. I then made a gasket using Mr. Gasket sheets and that blew as well after a period of a time. The all metal gaskets are the only way to go. However, no gasket will seal the flanges together if they have warped and become not perfectly flat.

 

How are you seriously going to say wrong when this exact thing happened to me....especially on an obd1 car ? And it won't throw a code until it gets so bad that your car starts stalling. Even then, it will only throw a code when you accelerate for 5 seconds then imediately decelerate for 5 seconds. If you don't believe me, look at the procedure for testing the oxygen sensor using driving conditions in the Helms. You couldn't even prove I'm wrong to why say I am ?

Simply hilarious.

 

You're claiming that a leak after an o2 sensor causes it to burn out. Now, that is "Simply Hilarious".

The true way to test an oxygen sensor is with a voltmeter or a good quality live scan gauge. A driving test to check for a bad o2 sensor? Wow, how accurate that must be.

Mine did not start stalling but my CEL came on. I suppose that if you take the lower portion of the exhaust manifold off it will cause the vehicle to stall? No. Hell, I even disconnected my primary o2 sensor while it was running and it didn't die. Nope, it simply went in to safe mode and poured in extra fuel. I truly hope your post was a joke.......

 

Well anyways regardless who's right, I have found the ultimate solution to my problem, the guys at Cb7Tuner.com are my saviors. Check this out, you can get it at AutoZone,







Multilayered steel.

 

Do you bros know where to find an acceptable replacement gasket for test pipes?

 

First of all, at no point in time did he indicate in his original post that he had an lx/dx, which are the only two cars that have the oxygen sensor in the exhaust manifold. The se/ex cars have the oxygen sensor in pipe A, which can easily get fouled by either rtv or gasket material that passes past it.

Umm no. The first test you do is the drivability test. As taken from my Helms...."Road test with the transmission in 2nd gear, accerlerate using wide open throttle for atleast 5 seconds. Then decelerate for at least 5 seconds with the throttle completely closed. Is check engine light on and does it indicate CODE 1? Yes, Go to page 11-34 and perform test for CODE 43." This is how you test for oxygen sensor issues(notwithstanding the heater circuit which would cause a different code to luminate altogether).

Even if you do the secondary test which can be time consuming you have to do it using the Honda test harness which hardly anyone has anymore. I'm not even going to get into using a propane torch to test it...not really even worth it and most probably would damage the sensor, assuming you have the tools and the skill to do even do it. Find a mechanic that even knows how to do that, let alone a backyard mechanic.

I never said anything about an exhaust leak causing a car to stall....it won't until the oxygen sensor fails completely. I was strictly referring to something such as rtv or gasket material causing it to fail prematurely...or in my case, within 500 miles of some exhaust shop using some rtv material.

lol if you disconnect the oxygen sensor and the car runs better that means the oxygen sensor is the culprit...which apparently now you have found yet another way to test for a bad oxygen sensor. Disconnecting the oxygen sensor will cause the ecu to run predetermined air fuel values until the code is cleared. I guess you didn't know that beforehand.

Now you know, and knowing is half the battle.

 

^ lol where to begin? So much controversy in your own statements....and sudden new information not mentioned previously.

Mishako thanks for the info! That definitely seems like the best way to go!

 

I just want to know if anyone can tell me would the gasket fit my h22 type r h22a7 exhaust?
