Little update, received the manifold after welding was finished and also received some misc. things. Used a vibrant fitting from the engine to the oil inlet on the turbo, part No. listed incase anyone is curious bolt size that buttons up to the engine is M12x 1.25.
oil drain flange looks to be well made and comes with an O-ring.
Have a couple options for the oil inlet on the turbo, was thinking of using the flange. What does everyone recommend left or right?
Oil drain is installed and looks to be about 1/2" away from the manifold. Should I be concerned about heat?
Vibrant says there hoses there hoses are "capable of handling operating temperatures ranging from -40 deg F to 300 deg F and elevated operating pressure of 500psi."
