The car is puffing out clouds of white(seems to have a hint of light blue in the color I think) smoke out the tailpipe and the engine hesitates when the puffs come out. It's also trailing a bunch of smoke after the puffs. The fumes don't seem to smell like burning coolant nor oil but some strong burning of something.
What was done before this occured:
1)changed out a coolant line that leads from IACV to T.B.(broke) + bled coolant
2) pulled off valve cover, pulled off far left exhaust cam cap to put hondabond around cam seal(was leaking) + installed cam cap back on & valve cover back on.
The next day, after driving around briefly, the above incident started occurring (smoking).
Any suggestions are appreciated.

 

Sounds like your car is backfiring. Did you reuse the old valve cover gasket or did you replace it and the spark plug o-rings. Pull your spark plug wires out and check the spark plug holes. You could have oil in one or a few holes, and that can be causing your back fire.( hesitation)

 

new gasket and spark plug boot seals, no oil in spark plug hole. No oil or coolant leak. Oil and coolant level seems to be the same also. Compression in all four checks out good, timing is at 16 degrees, + no overheating.... I'm stumped. Someone please help.

 

ttt

 

Have you done a leakdown test yet?

 

no, don't have my air compressor here yet (just moved). The smoke just started after doing the above basic maintenanence though.

 

come on, where's all the real tech gurus????

 

blue=oil

check all your spark plugs and make sure none of them have oil on it ANYWHERE, you could have disturbed the seal for the spark plug cylinders and where it meets the valve cover

or it could be somthing totally unrelated to what you did, and alot worse.

 

I think I had some oil on the thread of the spark plugs; I replaced the spark plug too btw, I'll check the new one now. I'm gonna try to find a camera & post the old spark plugs, there something weird looking about one of the prongs that I don't know what it could be. I don't think I did anything wrong because it was basic b.s. maintenance; but at the same time, how could it happen right after I did that . Oh yeah, I gapped the new plugs to .044"--is this correct for 93 b18b?

93 b18a....and for LS i normally go .035 i think

yeah probly wont solve smoke prob, but blue smoke means oil is burning...

Though it didn't smell like coolant nor oil burning It's just this bad weird burning smell. Both my coolant and oil level are cool + no mixing of either in the reservoirs.

 

Running rich will also cause white smoke... If I set my fp a little to high, white smoke will appear... Sooo, you might look in the direction of your fuel system. Also, I have also seen a white cloud of smoke coming from a HF, when something in the dist. was failing...

That was more for example, about white smoke and fuel on the HF with bad dist..

It "should" throw a code if something was bad in the dist., like you mentioned. However have you checked the ECU itself for any codes, rather then going by the dash light...?

Might take a look at the fuel pressure regulator. It would be next inline for causing to much pressure to build in the system, if it were failing for one reason are another. After that would be the MAP, it has the most control over the injector pulse width.

So you basicly pointing me towards fuel system problem huh (for the clouds/trailing of white exhaust smoke)? The fuel pressure is cool btw.

 

Try and get the ckf code 54 fixed before trying anything else... That could be the main reason why it's running rich, the ECU is in Limp mode.

 

*UPDATE* Just for the helluvit, I adjusted the valves and changed the spark plug gap from .043 to the minimum: .039 and the smoke seemed to lessened. Now only sometimes under hard acceleration, there will be hesitation and then a cloud of white smoke puffs out. Still working at it to eliminate the intermittent puffs of smoke.......

 

i'm having the same problems too. i got white smoke and from what i know..white smoke=coolant, so i checked my coolant reservoir, radiator, dipstick and oil filler cap for some traces of oil but found nothing.

my SiR is turbocharged using the hack and sometimes when i drive hard in boost white smoke would come out of the tailpipe then it'll subside after idling it. sometimes it doesn't smoke if i drove hard in boost. it's really wierd and driving me crazy.

does your car smoke all the time even when idling? coz my car smokes if i drive it hard in boost but sometimes not and smoke usually subsides after idling but one time it still smoke during idle.

oh btw, i've posted this in the FI section but didn't get any help.
