What is this thing?

Post by TuHandy »

Quick question.....

What are the two smaller tubes that go to the intake side of the turbo, located right at the intake of the turbo. They go into some kind of fitting that has a electrical connection. I know that the smaller tube (1/4"?) goes to the intake manifold behind the power steering pump, near the T-stat. The one that has the 90 degree rubber fitting that I replaced.

Where does the larger one go, and what is the electrical device that they plug into at the intake tubeing of the turbo??

Thanks

Noone knows what this is????

I traced the larger tube under the intake manifold and then it goes into some type of container? which is bolted to the side of the block under the intake manifold. There is also a tube that goes up to the valve cover. The one that is under the spark plug cover.

So, what is the function of the "container" which these hoses go into (the one under the intake manifold). I have looked in manuals and on line but Cant find what it is.

I think its some kind of vent that exhaust's the gases in the motor, not sure how it works.

Anyone???
