HWY, motor oil everywhere smoking no check engine
Hey, wonderful world and friends. I was driving on the highway in the USA and my motor started smoking and there’s oil everywhere under the hood. I got a slow drip now that I’m parked on the left side facing the front of the car.
I’m currently waiting on the tow truck and just wondering if anyone might have an idea what would cause the oil leak without a check engine light? The car still starts and runs good obviously I’m not gonna drive it but there’s oil everywhere.

I suspect oil filter housing and the 2 lines running to/from it. That is the highest point for the oil flow. Might also be the oil cooler below the intercooler or the secondary oil cooler in the passenger footwell
I just posted a video on how to remove the oil filter housing.

Hi,
tech in Kalamazoo advised the oil filter seal broke.
last oil change was a few months ago at 136,000 miles. Currently has 141,000.
drive to Michigan and back a few times this past few months from Cincinnati, Ohio. About 300 miles each way.
odd that it would break driving down the highway don’t you think?

I've read about over-zealous oil service techs who over-torque the filter cap, and fracture the plastic. I'm not sure how susceptible the cap is long term to heat cycling stress, but I keep a spare in my box of filters just in case.

Could also be the o-ring between the oil filter housing and engine block. Requires a 46 or 47mm socket to replace. Happened on both my W210 and W211 E55s. Nothing quite like crawling under the car and thinking, "Where did all this freakin' oil come from"?
