I know mines not a HG, none of the signs. If my exhaust smelled sweet, believe me, I would share it here first.. lol. And spark plugs only have maybe 400 miles on them so I will pull a few and see how things are doing. Changing my oil in/at 100/500 miles to send off to the labs for re analysis. Hopefully engine doesn't show any more wear than before... If it does, then ill have hard decisions to make. If not, Jerry will have to help me make it faster...

Cij911 is correct with his comment, but also oil seeping down the threads on the spark plus will give you this also. Oil seepage caused by leaking valve covers into the spark plug opening then through the threads of the plugs. There was a posting of someones plugs recently which showed motor oil on all the threads. If the smoke is only puffing from one bank then that would be the first side to remove the coil packs and look into the plug opening with a good light for oil. Or just remove them and check for oil soaked threads and a blackend porcelain, also again look into the opening with plug removed for signs of oil seeping from the cover. A test for valve seals is to go down a slope in a low gear without touching the gas, therefore using the motor to hold back the car, 20-30 seconds, (2500-3000rpm) no brake, then punch the throttle and look for blue trails coming out of the exhaust, this will indicate a seal issue.

Valve guides and seals are a common problem with higher mileage cars, but nothing I would worry about...Sure if you are racing professionally or have excess money to blow, you could always do a top end rebuild....
I would also recommend installing catch cans to keep oil out of your intake...

Serge, WOW, First is that the air matic compressor humming away, sounds like you have a leak or sitting on that driveway is causing the system issues.
Now for the smoke, I'm betting oil for two reasons, first the car does not seem to miss on startup but sounds "regular" and also the smoke is quick to show out the exhaust pipe because it "the oil" is part of the combustion . Think of a 2 stroke lawnmower like a Lawnboy when the oil and gas mixture is rich the mower will smoke a lot on start up then get less as the mower warms up. Your issue might be associated with leaking valve cover gaskets in the spark plug openings, as stated before pull a bank of plugs and check for oil in the hole as well as on the plug itself, PCV ventilation is also a possibility where oil mist from within the valve covers is drawn into the intake manifold and pulled into all cylinders. This is the reason you see guys putting catch cans on the PVC line to stop the oil from entering the manifold.
Just for piece of mind does the smoke "on initial startup" smell sweet or does it smell like oil, I'm guessing oil.
Also after warm up and car is driven for say 5 miles on the highway will the smoke bellow out " as on startup " if you tap the throttle a few times car in neutral after pulling off the road?
Bottom line this is not a normal situation and needs to be rectified.

It is the air compressor humming away : ) Front tire was low on air ...
I think my PCV stuck in open position and oil mist is drawn into the intake. I will have the plugs check this weekend. After car driven for 5 miles the smoke goes away completely.

Glad to hear that was only the tire being filled up, I have never heard a Air matic pump that loud, LOL
PCV is a good point but would expect the car to smoke when hot while running down the highway then flogging the throttle for a short time, which would increase the air flow going into the manifold as well as draw more fume out of the valve covers.
Good Luck

Serge, there is a good writeup in this blog DIY - PCV Valve / Breather Hose Replacement (M156 E63)
Read more: https://mbworld.org/forums/w211-amg/...#ixzz2SdKgOfUx
Looks like a pain to get at but good luck
By the way how many miles on the car and has it ever been overheated?

That is alot of smoke...Not Tony Stewart...
Keep an eye on the oil level....could be PCV or cover gasket.
The PCV is easy if you remove the intake...then you can change intake gasket replace with new bolts and new PCV...
If the plugs have oil I would say PCV...Does not seem to misfire. I would think misfire would be common if it was the cover gasket...
I had this issue on e39 M5 and it was the PCV.....
FYI...I had to edit and retype PCV ...Just finish a plumbing job using PVC piping.

Well unfortunately you would think the previous owner would have fixed the problem if it was as simple as a pcv valve. My guess is he had problem professionally diagnosed and was unhappy of potential costs so he sold the car :-(. You shoukd check dealer records, you may find it was there and problem was diagnosed. something like that could be a piston ring, once car warms up may have a better seal hence why smoke stops. although it looks like white smoke judging by video. no hint as to what it smells like?

I can't tell what the smoke smells like. I checked with dealer and found nothing in the records. I will start with PCV and will see what happens next. I am getting CEL P0444. I don't think i am getting any misfires.

Serge, do you hear the purge valve ticking at the front of the engine, passenger side under the cover with the chrome Benz emblem. Remove this cover, just pops up and there are two other clips holding the cover to the both air boxes, When the engine is running you should be able to feel the ticking in the purge valve top canister, you will see a 1 inch black hose coming out of the unit. If the car sat for two years this is possibly stuck giving you the code.
Where do you live Canada or State side wondering if 98k is miles or km.
Any recent oil changes, or changes at all, Mobil 1 0w40 or ?
As far as the smell is it like oily smell, put a drop of oil on the exhaust manifold when it is hot and smell the smoke coming off.
Same with the coolant, place a drop or two on the manifold when hot and smell the fume coming off, this will smell/ taste sweet.
Now which is it oil or coolant smoke out the back of the car.
Are the levels correct for both, oil and coolant level in expansion tank

yohoo!- just got my e63 from the dealer , i complained about the white smoke at startup( not all the time) they did not see them happen the day it was there. but the mech. said to drive harder / and drive it on highway a bit more often..did a compression test also and was good.
oil buildup was getting stuck at exhaust he said.
my car is a CPO and have 38xxx miles.
im thinking of other stuff to complain (have another 7 mos till my CPO warranty expires) but the car is so solid! anyway, my service advisor said to wait till it expires and extend for another 2yrs more.
