Am I the recored holder? (Bluetec Oil Cooler Leak)
 

So the dreaded oil cooler leak hit this week with my 2012 E350. Plenty of the black stuff on the driveway on Sunday. Took it to my favorite indy shop in Charlotte. Much to my surprise, it appears I have the ORIGINAL orange oil cooler seals and not the upgraded purple ones. My W212 BT has 99,768 miles on it. The word here in diesel land is these seals usually go around 50k or 60k. So...am I the record holder for most miles on the orange seals? Post you responses here. :)

I saw this post a few days ago - I am surprised nobody has responded, but that's a pretty rare car. I had one when they were new but never kept it long enough to develop any problems like this with it. I also had a 2007 Jeep Grand Cherokee diesel with 40K miles on it, and I had issues with the intake to turbo orange seal. I do recall it was orange. I can only imagine that the oil cooler seal was starting to do the same too.

Is that seal hard to replace?

It is a major pain. It sit in the valley below the turbo intake and between the ignition coils. 8-10 hours for a pro and 14-16+ for your average DIY-er. Many, many bolts. Te new oil cooler seals are the purple type. Supposedly better than the orange ones that were removed. I may or may not have done the swirl flap delete while it was opened up. ;)

Sounds about as fun as my 3 day engine mount job on my E350 4matic LOL

Just did mine. Oil leak at 120K miles - orange seals. Now purple.

I only made it to 50K before my oil cooler seals leaked, and I swapped them.
DIY was 16 hours, and a lot of that time was cleaning the intake of gunk. The shop would not do this unless instructed to.

I had to change my oil cooler seals , original ones were orange , and i also replaced them with orange ones. So the question is... purple seals are for certain years or certain models?? Because whe i was shopping for them all i saw were black or orange

I have records that on my 2008 E320 BT the seals were replaced at 140k.
Sure it sucks where $5 seals cost you 4-digits in labor cost, but it is what it is.

Is that "E320BT" Or should that have read E250 BT ? or E320 T ?

I made it to about 120K before I proactively did mine, but I still didn't need it at that point. It is a 2007 W211 OM642
