Catch can users on their OM642
So I was wondering for the people that have already have them installed on their OM642 or know someone that has them installed on their OM642, will it possible cause too much pressure and might possibly blow some seals to cause leaks? I have been reading up on catch cans and many people are against them due to possible leaks. But can't find any Mercedes owners taking about the negatives. To address the second negative during winter, some have install heat pads on the catch can so they don't freeze or just unhook them.
Just wanted seeing what you Mercedes diesels owners feel. I am hesitant now after reading about the negatives.
Thank you all.
