Breathing Heavily

TD5 discovery 100k

Just out new Turbo on after failure
Checking oil found diesel in it so replaced injector seals

Drove for a day then had revving up symptoms of turbo Failure
Checked Turbo and was fine but was breathing heavily due to diesel in oil again and was running on this

I suspect Cracked Head any other ideas before I waste any more money

Oil/diesel in the intercooler? Was the intercooler cleaned out when the turbo went bang?

yes it was

When you disconnect air intake from turbo it stops blowing oil / fuel mixture from Inyercooler
Oil level up horrendously

Have done seals on injectors

Hav espent 2.5k on car since xmas wish i had never seen it as it is totally unrelaible
It has only done 100k so I cant believe its done a Head gasket that swhy I am looking for ideas as no one at Garages nknows anything about these

I have just scrapped a 300 with 300k on it and it was still pulling like a train and my landcruiser has hit 200k with not a spanner on engine
Why cant landrove rmake anything relaible anymore and why are their no garages who can fix them

HELP

Check the fuel lift pump, don't know if the td5 has a mechanical pump or not, but if the diaphram goes fuel will leak into the engine, may also be worth checking the return fuel pipe is not blocked, as i have known this to push out the front seal on the injector pump if blocked, this happened on a Landcruiser based engine and not a Landrover, but it might be still possible.
