I have inquired with my dealership a few times voicing my concern about the white smoke blowing out of my exhaust at WOT from ~6K up to rev limit.
A few things I have checked:

Spark Plugs; white on electrodes...clean, no oil residue. "pitting" around the base of the threads (where the electrode attaches to and all the way around) on 3rd plug over form the left (2nd farthest from dist)

Oil level: After an oil change (Oil was verfied at top of top hole) and after 1000 miles oil is now down about 1/8th below top hole ( I drove it like I always do) I will check again after another 1000 miles

Rear Bumper: Soot all over it with black speckles, not oily to the touch...seems like carbon more than oil. I do NOT have gaskets from the CAT to B pipe and Muffler to B pipe.

People are complaining to me Im blowing crap all over their cars when they are behind me!

The Dealer wants me to wait til 30K and do the valve adjustment (had one at 15K) and just live with it..I told them I was concerned about plugging up the CAT and Fouling up the 02 sensors.

I have 22K on car now and still under warranty...any suggestions on what else I could check, or have the dealer check...

The Service guys dont know ****..I think Ill walk back and have a few words with the guys who actually know something...

 

Black smoke, right? Every single VTEC Honda I've ever seen does this. They just run real rich up there to be safe I guess.

EDIT
Oh oops, I just re-read... white smoke. Any sign of oil in your coolant or water droplets on the underside of your oil cap?

white = water
blue = oil
black = fuel (rich mixture)

but I'm sure everyone knows this already.

Have a leakdown test performed. White smoke is usually cooland, but you can smell this. More likely it is oil (some variety of grey) burning (leaky valve guide or bad rings). Leakdown should let you know what's up.

If that turns out ok, then its time to start looking at ignition and fuel delivery, but both of these would have other symptoms (missing, lack of power, etc).

 

No other problems..car Dynos strong...

Ill do a leakdown and Compression test soon.

Bluish from of grey smoke..smells real bad and a friend was behind me about 5-6 car lenghths back and has **** all over his front right side FROM ME!! I mean ALOT of the SAME black specks as on my bumper.

 

No water un the underside of the cap...but it is Oily though!

 

Hmmm, oily coolant usually is a blown head gasket. Get that leakdown asap. And possibly a coolant system test (they add colored dye taht appears with UV light and then presurize the system to see if it's leaking).

How oily is it? Check your oil, does it look like spoiled chocolate milk? That is another sign of bad headgasket.

Leakdowns and cooland tests should be inexpensive.

 

Nah Al I think he means the underside of his oil filler cap is oily.

 

Its not the oil consumption I am worried about...its the smoke and residue thats spewing out.

 

Bluish white smoke = oil burning. Suspect valve guides if it does it when pushing the motor hard.

 

thats when it is happening...WOT...under a load...at HIGH RPM. Would a valve adjustment fix this?

 

A valve adjustment will make sure that the valves open & close properly. What is actually adjusted is the clearance between the rocker assembly & the valve. The valve guides are the parts in the head that the valve (stems) slide up & down in. If they are the problem ie oil leaking past, the new parts need to be pressed out/in, which requires the head to be removed.

 

Thanks man. Im still trying to figure it out, I will have an answer soon.
