cobra lost in the clouds

[temjin9876]

I mentioned this in another thread but I wanted more people to respond

here are the facts....

-engine has 6000 miles on it
-oil has been changed regularly (no visible leaks)
-first oil changed featured Mobil 1 synthetic
-started making a start-up noise coupled with a nice cloud of
thick white smoke so I checked the oil; VERY
low. I added some oil and the noise went away
-second oil change, Royal Purple synthetic. No start-up noise but am starting to get the cloud of smoke sometimes. It is not everytime, but sometimes. Oil level is still good and oil content looks clean.

so here is my question.



WHY THE F*** IS THIS HAPPENING?

thanx guys

I can't answer your question but you're not alone. Mine does it after it sits for a week or so.

[temjin9876]

mine does not need any rest period for it to happen

I had a cop question me about it in the parking lot once

really sux

supposedly, it's characteristic of some of the OHC motors. mine will do it only after a long drive, say like to atlanta. after driving down, then sitting over night, it'll do it first startup the next day and then no more. weird, but it's ok....(i guess)

Smoke signals! mmmmmm--

My car does that too. Called SVT 1800dipstick line and yes its official, they are flunkies! Local Ford mechanics know nothing of this either. I say its a sensor of some kind. My engine tries to notify people from miles away. Embarrassing to say the least.

Engine doen't use a drop of oil. Wierd.. Just did the first oil change today. Drove to South Dakota and back and not a single problem. Sometimes I'll go a week before the car sends a smoke signal and other times it will be the same day.
Several things are certain...
Only smokes on start-up.
The problem is intermitant(pardon for spelling)
Smoke emitted is white with a light purple tint, more of a fuel smoke
Engine stumbles a little
I believe the problem is on the intake side and its a sensor.
Did some experimentation. Turned the key on being careful not to touch the gas pedal and waited for 10 seconds before starting the engine and that seemed to lessen the number of smoke signal episodes. I'm getting ready to take out my spark plugs to inspect for fouling or build up. Engine runs strong! Dont understand the smoke. Will post again after I take a look at the spark plugs. Just for measure, all the fluids and filters are good in the car. No sign of leakage, no loose fittings, etc..

[temjin9876]

please get back to me about the spark plugs. I would really like to know if that is it.

peace

I was having the same problem with the startup noise and occasionally the smoke when running castrol and a fram filter. After switching back to motocraft oil and filter this problem has almost completely stopped. No more smoking and just a trace of rattling on cold startup once in a wile. :( I would like to run synthetic oil but I have been told that it makes the problem worse than the castrol did? I am in the process of installing a preoiler when that is done I will try some other oils and see if the smoking comes back but preoiling should stop the noise.
