most hondas give off black smoke that is actually just carbon that is built up in the exhaust system... burnt oil is blueish

m4rk3y_sol

does this look like carbon to you?

i really hope it is... i replaced the cat a couple days ago, well i put a second hand cat on as when i bought it the zaust ad a decat pipe.. and needs a cat for test...

i cant remember seeing smoke before putting it on

gtlaw1

looking at the video it doesn't look like carbon....it looks white.... if it runs fine don't worry about it for now

whoop! i need to get it through an MOT (dunno if this is just an english thing) so i can use it on the road.. so i need to sort everything out on it so it is like a new car lol


if any one else has any other opinions please let me know

cheers

Is this under cold conditions? just started the car..?

If the car is warm and its shooting out "white smoke" which it looks like.. It most likely is your HG.

Give it a good leakdown or Comp test and it will answere your question.

good point. I had mine sit for two and a half months, and when I started it, it has smoking like that. But then it went away.


OP-Have you been keeping an eye on your oil level in the car? If so, anything noticeable?

BigDeal

I dont know how many times i've heard people go crazy because some white smoke poofed out when they warmed up their car... It's just condesation that has built up in the exhaust.

Honestly leakdown test the thing and call it a day.

i wouldnt be bothered if it was white smoke... it just looks dirty... its whitish until about 6k revs then it looks dirty... this is why im scared..

what does a leakdown test consist of (excuse my lack of mechanical knowledge lol)

cheers ppl :D

Go behind the car and have someone rev the engine and smell it. If it's coolant (lets hope not) you will know for sure. Coolant has a very distinct bitter/sour smell. Burning oil also has it's distinct smell. Whatever you do, do NOT put your face anywhere near the exhaust. Just try to smell the smoke.If it barely smells, it's probably condensation.

Let's hope your car never does this
