CT12A Advice

i just received the twins today, i found oil on the compressor housing fins. im guessing thats a bad thing. idk how the compressor fins would get oil on them, the only way it would is from the valve covers. how can i check if the turbos are blown, because if i bought a set that are blown that would suck so bad.
Not sure about how the 1j is plumbed off the PCV system, but its possible for the oil vapor to be on the compressor wheels.
The Vent from the Vavle covers for Oil Vapors goes right to the intake tube for the turbos so it is quite posible to get oil on the compressor wheel.
You can do the basic checks on the turbo spinning the shaft to make sure it moves easily and freely, pushing in and out to make sure it is not moving far or moving very little at all and same with Side to side
Basically it should barley move the shaft should not be able to wiggle around much at all.
Other then that i am not sure how you could tell if the seals in side are bad. I found out for mine the hard way by putting them on and realizing that they are burning oil (common issue with the CT12A's )

Not to worry, they will be oily.
Remember, the crankcase vents straight into the turbo intake.
If nothing else, get a new set of crush washers for the oil feed, but that is it. They are ready to use.

I can't wait til the CT26 option becomes available. Once and for all the people that are happy with stock power levels can have something reliable.. like this guy.
Yup, it's a great replacement for the twins for reliability. Also if the lines are made long enough, you won't have to buy double when you upgrade to a performance single and manifold in the future.
