One thing to consider is an intake gasket seal failure. Removing the intake again may be a good thing.

Since the gasket is a steel shim gasket,and was replaced when i had the intake off this week, what should I look for to determine if a failure existed, btw, the engine was hosed off while running, to get gunk and crud off from the under the intake cleanup I did and to knock a socket I dropped out from the back side of the motor, and when I ran water all over the upper and lower portions of the intake there was no change in the running, which I would have suspected if there had been a failure, and yes, I really am fighting taking this car to a dealer, I am currently out of work, and my friend at a dealership in CA will ship me parts on credit, so I can keep changing stuff till the cows come home, but I don?t want to....just really perplexing me as to how the oil is so built up in the intake and if the problem that was allowing it to build up is gone and its all the residual that I?m still burning off, or if the problem still exists.....it?s just wracking my brain....

I do have to say, after reading some other threads and the like, I wasn?t surprised that you two are the ones who have replied first, and I am very happy to have your input as you both seem knowledgeable, and I appreciate your input and assistance

Its truly a pleasure to assist. I remember when I first started modding. Lots of questions with awesome answers. Though the site has matured over the years, the desire to assist whenever I can remains.

Back to the car. Were the VANOS motors removed? It may not be a bad idea to reset adaptation values within the engine management modules. There are so many variables on this car. So many sensors. get some electrical contact cleaner rated safe for electronics. Start removing sensor connections, spray, and plug back in when dry. Ensure a tight plug on the intake manifold adjuster motor on the rear of the intake. Perplexing!

VANOS motors, by that you mean the actuator located in the middle of both valve covers, no those were not removed.

Is the adaptation values reset done soley by disconnecting the battery, or do i need to plug into the DME to clear those items.

Ya, ive done all the wiggle wire tests and the like, i just cant seem to do anything to the car that will change the way it runs.....and im not sure if im chasing two issues with the smoke plume and rough idle, or if they are one in the same.

Any idea about what would make the car run perfect until it reaches normail operating tempature.....i mean its flawless....the whistle is gone and everything, then its just like POOF..here i am again to run like crap....ill try the electrical connector stuff tomorrow when i pull the motor back apart....this is really driving me nuts....

Any idea what size external torx socket i need to remove the retainers on the coils

update....

so I'm back to playing around with stuff.....disconnecting and what not.....pulled off the ccv valve cover and started the motor, what i thought was my intake leak whistle sound, turns out to be the ccv valve......removed the valve while the engine was running and pulled the spring located under the valve, whistle went away and the engine idled....PERFECT.....put the spring back in and it runs like crap and whistles, put in one of the original valves that was still ok, and the same condition exists.....WTH?????

Stretch the spring and re install

Who told you this? take the oil cap off, start the car and you'll find out the answer to this real quick. All of these cars have a vacuum. hence "Vacuum leak"

I hope the engine was cold!

Did a test today, and started it cold and watched the temp, and time it took from a cold start to see the issue arise, granted not really cold out, 86 ambient, but it took 9 mins from start at only idle for rough idle to begin and the exact temp was 70c or 158f....will test again tomorrow and see if same results

Yes, the engine was cold, i had just finished changing the water pump, and this seems to be the time when it all went wrong, i want to point the finger at the job i did, but have thoroughly gone over everything i could have possibly touched or left unplugs or what, and can not find a single thing wrong....just baffeled, have two dealerships in ca trying to provide me phone support and even they are stumped.
