Hi all,
The Honda my gf has (2001 Honda Civic LX (non-vtec) with and auto tranny) seems to have an issue again. It seems to have gotten the “truck” upgrade over the weekend.From what I can deduce with the 2 min. I looked at it today before going to work, it has an exhaust leak on the front / under the engine. Of course cause the back pressure is sucking (pun intended), it isn’t running too good.
Before I dive into this thing, has anyone had a similar problem on a honda civic? Just wondered if there is something I should look for that might save me time diagnosis where the leak is. I hope its not the exhaust manifold, from looking online, the cat is with the manifold and that makes it expensive.
thanks for your help

It is common for that bracket to break, I wouldn’t worry about it, the gasket and spring bolts will take up any vibrations. BTW that part is replaceable so I wouldn’t worry about welding if you’re intent on fixing it. Not a bad idea to keep the heat shield though, the ones on the pipes and cat you can loose but keep the one attached to the underside of the car, you’ll thank me in the summer. Keep us posted.

I got this thing all apart and ready for welding. I am not well acquainted with the angle grinder and had to drill out a spring bolt from the bottom, first time I had done that. Should have done that many other times as it was much easier than I thought.
Here are some pictures of it. As you can see this car has been through 11 hard winters in Pa / Oh.
I think I found the crack, the weld at the number 1 cylinder.
The spring bolt was here.
The top right bolt I had to grind off.
I am surprised this didn’t go bad at the gasket.

I got it all cleaned up, got the new bolts and gasket from the Honda dealer. One last question before I put it back together.
Should I anti-seize the bolts / studs that connect the exhaust manifold to the engine?
*Edit* I used anti-sieze on the studs and bolts. Its all back together, I just need to put the air box back on it. I figured while it was getting welded, I would clean the throttle bottle as the throttle sticked a bit. its all clean and ready to go.
Its missing some of the screws to hold the top of the airbox on to the bottom. So I am going to lowe’s to get a few screws and bolts to just bolt it back together. Better than dropping 50 bucks on a new airbox.
I’ll let yinz know how it runs tomorrow after work.

I would just in case you had to do this job again. I used anti seize on my studs a while back and have had no problems.

In my experience using anti-sieze on exhaust bolts is a waste of time, it usually just burns off. Aside from that the nuts used to hold the manifold to the head are locking nuts which means the use of lubricant’s is a no go. You wan’t to make sure they don’t work loose due to vibration and you’re back to where you started with an exhaust leak.
