Second gen Subaru diesel with variable vane turbo/plastic intake manifold.
The problem was due to a guy at the hose shop soldering the banjo fitting poorly.
The turbo oil supply hardline developed a crack from vibration. Cole had a guy in Las Vegas build him a new flex line on a road trip…and he soldered the fitting completely closed accidentally. 🤦♂️
Hard to find replacement parts for that Subaru ee20 engine.
Swapped to TDI VW engine.
