Finally found the cause of my burnt oil smell, after replacing the rocker cover gasket to no improvement dug in further and found...
a leak from the Cam Cap.
So a bit more difficult then the rocker cover then
Got it finished, and put a new Timing Kit and Water Pump I had as I was in there (taking the AVCS cam pulleys were a c*nt even with the proper subaru tool don't believe the videos on youtube!)
Then drove it to Whangarei as a test. So far so good it seems, no more leak onto the exhaust manifold.
Also finally managed to complete my Genome gauge install, as the supplied sandwich plate wouldn't fit. So went to pick a part to grab an adaptor to install it into the engine block. Then had to steal the pressure off my WRX as it turned out the supplied pressure sensor didn't work
Still, theyre up and running now, and they look good and allow me to track how the car is going which is what I want.
