is it ok for white smoke to come out of my exhaust when vtec kicks in? also, ive never owned a honda so is it normal for the motor to make lil noises like good rattle between 2000 and 4000 rpms????

 

what do you mean by good rattle? I'm sure you car is fine..

 

seems fine. the white smoke may be because your running too rich but on the other hand just hope your piston rings aint fried

 

well the car has 135k mi on it so its still good. but it makes this wierd nocking or rattling noise between 2k and 4k rpms, and it gets louder the longer i drive it. do u think something is lose on it? my friends say its the exhaust but its not like a clankingor anything like that. any suggestions?

 

my car used to throw out slight white smoke during vtec, when it was new... people told me it was running rich. now it throws out black, and now techies tell me i'm running rich.

 

White smoke would indicate a coolant leak possibly from a cracked head or blown head gasket.

how sure are u on that? cuz i just bought this car a couple days ago and that would be a problem for me.

 

if i was you would change ur pistons rings and check ur pistons. or ur head gasket might be gettin old or ur valves are goin bad. the same sh*t happen to me , upgrade my valvetrain and piston and rings. you should get it check out mane

how much did that run you?

 

doesnt white smoke mean your burning coolent?

 

The rattle is probablly the heat shield on your cat mine did the same thing.

 

my car rattles also at 4000rpm....im assuming its the header gasket because i have a test pipe on and i took heat sheilds off my headers and it still rattles...pretty gay.


and i have stock exhaust system only w/ test pipe.

 

DIdn't you get it check out before you bought it? White smoke means coolant....same thing was happening to me.

As for the sound.......Is it coming from your engine or the back of the car? This would narrow it down for everyone to tell what's wrong with it.

 

so i could have coolant leaking even if its only during vtec????

 

i doubt its a head gasket or cracked head...when that happens you'll see a lot of smoke and your car will overheat really fast. make sure there is no oil in your coolant.

Make sure coolant in radiator is topped off. Also in the reservoir. Then drive it hard. After, check the coolant levels in both. If they are low....


Sorry to say, you blew your headgasket for sure and you are burning coolant! You should get it fixed ASAP.

 

I always thought white smoke meant that your valve seals are bad.

 

my head gasket isnt blown and im not leaking coolant. so is that im just runnin really rich when vtec kicks in?

 

Your seals are definitely blown. If it's not the headgasket then its something else. You're not losing any coolant right?

 

my coolant leveles have stayed the same after an entire weekend of canyon runnin. thats about a tank and a half. wat seals? piston rings????

 

your pushing too much psi when your VTEC kicks on... j/p... not sure about your smoking problem... but i believe the knocking is your ignition timing, i had that problem.

 

Yea I think i kno wut u mean My GSR makes a big pop when I hit 45k Its crazy.

I dunno what it is But someone told me that I might have to use the LS head for a while

LMAO HAHAHA j/k
Good luck wit it Man

 

i would say coolant...but probably....vtec kikin too hard....haha lol....rattle?...what year is yo ride...probably jus ABS....

 

you should probably find some one on Honda Tech that lives close to you that knows more about B-series motors and have them check your car out. Or take it to a honda mechanic and have him check it out.
seems like it could be allot of different things... i'm sure this forum can stay open forever w/ people telling you what "might be wrong"
