Finished Oil spearotr valve replacement now I have white smoke

[ernaldamerican]

I finished the installation of the Oil seperator valve. Started up the car and white smoke was coming out exhaust. It was non smelling if thats true ( I was looking for a sweet smell). Any way ran it for 20 seconds and white smoke didn't stop. Shut it down and waited for garage to clear out as it encompassed the entire garage.

Waited 10 minutes went back out and started the car again. White smoke still coming out and filing the garage. Both tailpipes.

Now I assumed I would get smoke until the oil that got dumped into cat and muffler was burned off.

First question is this white smoke isn't thick but the entire exhaust coming out is white. It doesn't smell as far as I can tell (like burning oil or anti freeze.

Any ideas what this white smoke is from (i.e. is it let over oil in the cat and muffler best guess). How long would you expext to idle the car until its gone?

Thanks for the help.

Update on white smoke in exhaust after replacing oil separator valve on my 2003 x53.0i. I figured that there would be oil in the cat and muffler as it was in the cylinders. Started car last night ran it for about 1 minute and fogged out the open garage with white smoke. Shut down after a minute, and restarted 10 minutes later. Ran for about 1 minute and shutdown. Again smoke out the garage and I mean it was a white out. Ran the car this morning for 30 minutes at idle, shut down, let it cool and checked oil level, coolant level and pulled all the plugs. Everything looked good. Ran the motor again for 30 minutes and did the same routine. After the first 30 minutes smoke definitely dropped off, after second it dropped off again and now it looks like the exhaust you have on a cold day when you first start. Took the car out and went about 10 miles on the high way had it up to 80. Ran fine but each time I got on it you could see puffs of smoke. Got home and the tailpipes are soaked in oil.

Pulled plugs and they are clean and dry, oil level is full and coolant is full. I think it will take a road trip of about 100 miles or so to get the cat and muffler clear of oil. No fault lights at all during the initial failure of the valve

Sounds like a good plan. Good thorough steps to follow to check oil, coolant, and plugs after the repair, when you still had smoke. I wouldn't recommend you keep up with the 30 minute idle cycles (that is what causes separator problems in the first place). Get it on the highway and drive it. Good luck.
