I have a 1996 Lx with a D16y7 and I just removed the heatsheild on the exhaust manifold because I thought that the gasket had gone bad after noticing some smoke coming from around the manifold. After removing it I discovered there was a crack down the manifold that is about 3 inches long! Should I replace the manifold, have the crack welded, J.B. weld it? What's the best fix?

 

replace it
i've seen it happen a couple of times

 

R U serious? sure u can half *** it for now and put j.b. on it, but u'll eventually want to replace it, but while u gotta replace it anyway get a header 4 her.

 

replace it asap cause a crack on the header is gonna affect the drivability. exhaust leak before the o2 will cause it to run rich

 

yeah, it has already dicked it up. I bought a new o2 sensor for it already. I wonder if the leak made the other one fail? Is that possible. As far as getting a header, that is a possibility, but money is tight, and keep in mind this is only a D16y7 with an intake and a cat back, SLOW! If I get the header, just wondering, I have heard both good and bad about the megan racing one.

 

go to your Honda dealer and have them replace it for free if it is causing a CEL.

95-97 civics have 150k mile/ 14 yr. extended emissions parts warranty.

My 96 hx had a crack in the exhaust manifold, and they replaced it along with the o2 sensor for free!

Okay, so I just talked to the guy at the Honda dealer. It is under warranty!!!! Thanks sooo much! I have an appt for tomorrow!

 

put your old O2 back in if you have it and keep the newer one for a spare. No sence in loosing a good O2 sensor at the 120 a pop

 

they all do that, good luck finding one at a junkyard that doesnt have that notorious crack.

You could relocate the cat convertor to underneath and run some other header if you plan on keeping the car
