N54 Running Lean / Massive Smoke/ Coolant In oil

greye93 · 03-24-2021, 11:13 PM

Hello, Sorry for putting 3 series stuff in the one series side, but I'm really lost on this and could use some help if anyone has any ideas on what this might be.

My 08 335i N54, has an HUGE ISSUE!

This is from my previous post, update is listed further bellow.

Larger Silicon Inlets
BMS Cone Intakes
VRSF Inner Cooler
Upgraded Turbos
MHD Stage 2 Tune
50/50 E85/E91
DKM Stage 3 Plus w/ Single Mass Flywheel
VRSF Cat less Downpipes
Oil Catch Can
Upgraded Low Pressure Fuel Pump
VRSF Charge Pipe

After my new clutch install I drove the car 600 miles all moderately, under 4000 rpms. After I broke on my clutch I drove the car HARD, some really good pulls. After some time I noticed there was MASSIVE grey/white smoke, also may I mention when I say massive smoke I couldn't even see out my rear windows. When I got back home I checked my oil level and it was good (if the oil sensor read it properly), next there was oil in my coolant. The car did feel to have a power loss but I was able to drive 50 mph to get home.

I'm pulling codes

2C2C not present
2DED not present
2A2C not present
2C7F not present

Update

Main Issues,
Massive white/grey smoke from tailpipes (when I save massive I mean a big deiseal roiling coal but white)
Power loss, but able to go 50 mph
Oil in coolant
no coolant in oil( that I see)

I did a leak down test and I have a leak from the oil filler cap. I don't believe this is normal, but I'm also worried this is the only issue I have if oil is in my coolant.

ANY HELP WOULD BE VEREY MUCH APPERICATIED!! THANK YOU!!!

I hope it's just the gasket that let go and not the head or block. Either way, you're rebuilding your engine. Sorry to be the bearer of bad news. Had you been noticing any detonation?

First, check oil cooler gasket.

How many miles did you drive after you first noticed the problem?

The OFHG can cause oil / coolant cross contamination.

True, but a sudden burst of white vapor and limp mode sounds a lot scarier than a bad OFHG. I’d prefer to be wrong just because I don’t want to see anyone go through that, but methinks it’s pretty serious.

OP, how much coolant do you have left? Do you have a noticeable drop in coolant?
