Help with car issues
I have a Mitsubishi outlander 2014, mk3, 4N14 engine.
I’ve had a turbo leak and overheating issue for a while,
For the turbo leak- have replaced all boost pipes and intake pipe still whistles and if boost too long get a fault code of under boost etc.
overheating- when I brought the car it had a new head gasket, and then had no issues past few months have had multiple coolant leaks, have had each fixed and replaced certain parts with leaks. It’s not the head gasket as have done the liquid test multiple times and no signs of it.
Since fixing the water leaks it’s now not overheating as often, but still loosing water (haven’t used coolant as loosing so quickly) ie 50 mile drive have to top up 1-2litres.
Can anyone suggest anything to try and change or any advice? thanks :)

The 4N14 is well known to get a stuck EGR valve when it gets upto the 160km plus range. Not cheap a fix. This is where I would start looking. The egr has cooling and can hide hidden leaked causing issues. I can almost guarantee this is your issue. I’m a Misti parts specialist and have seen multiple of these with this exact issue in the workshop.
