Note: the photos are from a L405 Range Rover that shares the same SCV6 engine.

The coolant crossover pipe on 2013-17 SCV6 and SCV8s WILL fail someday as our cars getting older. It requires taking out the super charger, but detecting and fixing this earlier could save us an engine.
My 2014 RR V6 with 70k miles is spotless clean in undercarriage areas, coolant level never drops, engine runs great, no light whatsoever. However, I found the crossover pipe leaking in 3 mins. Check yours today!

Tool you'll need: Borescope/Inspection camera, I got this oneon Amazon.

First off all, just to show you the location of the crossover pipe, it's between the block and the oil filter housing. (Not my picture. The one in the red circle is the updated part)




The tool you need is any Borescope/Inspection camera



Pop the engine cover and insert the camera into the small area near the oil filter housing.




Try a few different angles, try to angle it towards the engine block, and that nasty orange means you just saved an engine.

 

The intake manifold does need to be removed for that job, so it's a bit of labor; $450 does seem a bit high, but it's the dealership, so I'm not surprised. I would look around for a good independent repair shop in your area. It's around 2-3 hours of labor, so my guess is $300 - $350.
