Had a slow leak for 12 months and I the last month it became fast. Coolant leaks along the valley and down the back of the engine.
Difficult to find even with an inspection camera but apparently this is not unusual, the plastic thermostat housings are know to split.
The only way the leak can be confirmed is by removing the intake which can be done in one hour without removing the injector wiring harnesses thanks to advice from another member.
I removed the egrs to help with access but I also wanted to inspect/clean them.
Each egr takes 30 to remove and helps access to remove the rear coolant hoses from the thermostat housing.
New housing arrived from British Parts uk in 4 days. Old one was very tight and ended up snapping off the pipe. I had to carefully lever out the Broken peice. On inspection the plastic looked welded to the block.
Once removed I had to sand the surface as smooth as possible for fitment of the new oring seal.
When fitting the new thermostat housing apply Vaseline to the oring to help slide into place. I did not do this the first time and had to remove the housing again as I damaged the oring on install.
Accessing the EGRs and Thermostat housing - can you share Paul's advice?

Can you share Paul's advice? My mechanic's advice is that it takes many hours to remove the manifolds, access the EGRs and access the the thermostat housing]
