I'm trying to trace an oil leak from the back end of the engine - I notice that if I drive the car hard, 300td w123, then I get a bigger pool of oil deposited on the garage floor compared to if I pamper it.

With oil filler cap off, I get a gentle chugging of gasses exiting - I'm wondering if my leaks are due to excess pressure blowing oil thru engine seals.

I do need to check the breather system to see if that working okay ...

Just soem thoughts...
