Hi everyone today I’m looking at a 2018 Bmw 320i with a small turbo. I’ll be showing you where to find the rear main oil seal inspection hole. Be sure to use gloves a flashlight and a small flat head screw driver to open the inspection hole if you have a big enough leak or seepage then an inspection mirror will not be necessary.
