Exhaust smoke burning eyes

[JOJ]

Salam every one, I am back with unique problem again. And it's really getting on my nerves,, I have honda civic 1.8 recently bought from a friend and he kept it really really well. The car was doing fine in all matters but now after I got that bad Hit with super speed breaker in the middle of nowhere. I am having problems, I got my car hit by a big rock right on the exhaust pipe in the middle (under) of the car. After that my car sounded a bit heavy and lost almost 30% of the performance, I got my car checked by a mechanic n he said it's all right, Pipe is saved but u better change ur spark plugs. The thing is I am not getting the same acceleration as I used to get when I floor it, it feels like if something is holding the car back. 2nd thing. The white smoke coming out of car exhaust is really burning my eyes. White smoke shows up for 5 minutes when I start the car in the morning and after that it just burn eyes. Alot I mean. What is the problem? How I lost my power? Acceleration is low and that also all of the sudden. I do have CAT installed recently from honda north. Someone told me to change my spark plugs so will that solve the problem? M using iridium spark plugs I don't know the exact numbers yet. What should I do???

Are you sure it's not blue smoke as opposed to white? In the given scenario I'd expect it to be black.

Exhaust does burn eyes, and smells, if you're running rich. It burns even worse if it's running lean. Better to avoid it at first place.
First thing I'd do is to pull and examine the plugs. Plugs are your key hole to the inside of a working engine, and a keen eye can tell a lot from a plug inspection alone.

Does your primary O2 sensor, and its surrounded area look okay? Do you have any CELs?
You cat con is in the engine bay, not underneath, so that's nothing to worry about.

Are you suggesting his car's on fire?

seems like the o2 sensor has got damaged!

[JOJ]

@uiv yes m sure it's not blue smoke I haven't checked the O2 sensor but seems fine. Really not getting the problem

[JOJ]

@aamirq if O2 sensor was damaged I would have CEL on. All the check lights are fine. No CEL

How it burns worse when running lean

[irfansiddique]

throughly inspect the exhaust pipe, it might have a leak and because of that you are losing back pressure.

[JOJ]

@irfansiddique right Bro. I hope bas masla Mil point out ho jaye.

[uiv]

White smoke is caused by coolant burning inside combustion chamber. There's no reason for your car to do that. Are you sure it's smoke, not regular morning condensation?

Have you checked the plugs yet?

[JOJ]

@uiv no Bro it's not that. Actually it's not that thick but burning eyes like crazy

typo, i was pointing to no 4

[saboor73]

I "THINK" your problem is that a very lil amount of exhaust gases is leaking from somewhere from middle of exhaust and due to less of out of carbon going out of exhaust ECU is making it fuel mixture rich resulting is less power,smoke

1st of all Gas was leaking from the joint near the Cat. Well the whole story is. I went to honda north. They said they will fix every thing and if new parts including fuel filter installation takes place we will charge you 28000rs. I said do u know what Big B means he said no. I said BYE. Coz he told me the eye burning will not go away. Lol. Well I went to a friends work shop. He said exact as @saboor73 did. And opened the cat box and started cleaning it. I never knew it could be cleaned rather than replacement. Well he told me that it was dirty and joint had a leak also. He opened the throttle body in my absence I never do that but it was late. When I cam back to the shop he was holding the throttle body in hand. Well that made my cars rpm go nuts. It's not stable any more. Plus petrol bohut teezi se kam ho raha hai. I do not know how to fix that now. Well after he cleaned the sensors O2 and the air flow. He put some yellow liqued kinda thing in the Cat and rinsed it with that and applied water after that. I dint knew what's he up to. But I let him after visiting honda north. After every thing got cleaned n checked up the burning issue got Just a bit solved just a bit. It's not burning eyes like before now but it still has some thing in it which is not gone so far.
A friend told me to change the current denso iridium spark plugs to NGK IZFR6K11 Laser iridium spark plugs. I have bought them but will install them tomorrow to see if they make any difference as he said eye burning smoke is caused by the spark plugs n they have gotten weak. I am currently using denso sk20r11. Can someone tell me the NGK ones I bought are any better than the denso ones plz?? Well I don't know how to fix the rpm and the car petrol draining too fast issue after the throttle body cleaning .... performance may come back after plugs change. Posting pictures.

It's just steam.

Looks like steam and mostly viewable in foggy or rainy weather and early mornings.
