I have a 2010 BMW 335i E92 stage 2+ MHD, I started the car the other night and the low coolant light came on so I opened it and filled it but noticed it was weird looking on the inside after just dipping my finger in the tank I pulled it out covered in oil so I ordered the gasket kit, oil, coolant, and what not but my question is, would the OFHG cause the car to white smoke a little bit every now and then it’s not very frequent but under a little load, or I am gonna be replacing turbos soon? The turbos look fairly new from what I can see on the wastegate side and I don’t think it’s a head gasket because it doesn’t do it all the time. Thank all in advance

I’m sure you’ll defintely see some yes, don’t drive it in mean time until you get that OFHG/cooler gasket and o rings squared away ASAP.

Let previous oil drain for a good while and maybe consider doing an engine flush with liquid molys engine flush even though you would have to drain oil/filter that’s contaminated.. fill with a cheaper synthetic oil and filter and than add the engine flush. Let idle with 15-20 minutes than drain and re fill with youre choice of oil.

Clean well or replace expansion tank and clean replace main coolant lines. I’d my vehicle is want make sure all coolant/oil contamainted items are cleaned or replaced

It might the turbos that are starting to leak oil and causing smoke.
Does it have stock exhaust?

Replace the mickey mouse flange while in there, if you have not done it yet.
