Newbi with 335d leaks



Hi Guys, Recently had problems with a 12 plate C class coupe merc so i sold it and bought a 07 plate E92 335d and I'm really glad i did, its well specced but has high miles....This week i noticed a slight smell of oil in the cabin so today i took the engine cover off to have a look and i noticed that the "U" shaped oil feed pipe to the small turbo has a very slight this common and is it an easy fix ( i noticed the pipe is crimped) I also have a very small water leak at the front of the engine (top) from a component ( i don't know what it is) that has two 10 mill bolts securing it to its housing (looks like a very small thermostat housing in shape) but the bolts are inaccessible....any idea what this will be? Thanks in advance
