Leaking issues in my 200 4R - any gurus available?
Here's one thing I found!!
OVERHEATING, FOAMING OIL AT DIPSTICK OR BREATHER
-Oil cooler has insufficient capacity.
-Oil cooler plugged.
-High fluid level.
Since you didn't have a problem before the filter change it's probably not the first one and I don't think you're overfilling??
Could your cooler be plugged?? It would make sense.
