AND now there's smoke...

Brandondad · 07-05-2016, 09:40 PM

I have all the mods listed in my signature, (The inlets were put on a few weeks ago) Prior to that I had the typical oil thermostat housing leak, and an oil pan gasket leak. I took the car to my local shop (2 Master BMW Techs), they fixed the leaks installed the inlets and put in Penz. 5w-40 (prior had 0w-40). And now I have white oil smell filled smoke coming out of the passenger exhaust which didn't happen before I had the car in. Happens at decel's, or boost shift (auto). If I put the car in park and let it sit for awhile I can literally fill a parking lot with smoke. If coming to a stop I put it in neutral I get no smoke. I was doing some tests with DWP (JB4 menu 10) with my son driving behind me and the lower the DWP the more smoke, the higher DWP not so much at 5000 I didn't have any smoke at idle. Those are all the details I have for this, closing on my house next so my tools are buried to research anymore. I've read every possible post out there all with slightly different symptoms. Just trying to get some other thoughts / suggestions before I go down the checklist.. Thanks for any and all help!

When did you get the turbos ? How many miles on the turbos ? I know for a fact that the billet option caused many headaches with a lot of customers. There should be some post around here if you look you will find them.

How many miles on the car? Usual culprits for smoking are the turbo seals, and sometimes a bad pcv valve. Valve seals or piston rings are less common causes.

Turbo's were installed a year ago April and I have around 10k on them and 120,000 on car.

If messing with the wastegate changes the amount of smoke it sounds like a valve seal is leaking rather than the turbos.

Brandondad · 07-06-2016, 09:26 PM

Yeah... Well may just do a head upgrade and be done with it. Probably a matter of time if it's not anyway. Be able to tell once their in there, hopefully...

April was exactly the time when the billet issues were happening weekly. I was scared as hell that my RB turbos would go at any time but it was always just the billet option that Rob had problems with. I still think pulling the dp would be a good start.

How so?

My thought process is if the wastegate is more open and you get more smoke, it is most likely coming from before the turbo. Just a guess though.
