Cant find my leak

[droppinbottom]

Guys I have been working on getting all my boost leaks fixed and I have one more that I cant seem to find. It is coming from somewhere behind the turbo where it mounts to the manifold.
I am using the stock 14b and am trying to test it up to 20 psi because once all my leaks are fixed I plan on running 20psi. I notice the little arm on the wastegate starts to move once I get around 15psi. Could that have anything to do with my leak?

The motor is on a fresh rebuild and I am pretty sure all the gaskets are good and sealed.

Thanks for any ideas.

That would be the 14b/16g compressor housing o-ring.

Thank you oldman

I have been all over this darn thing trying to find the leak. Now for one more newbie question. Where does the o-ring go on the compressor? I cant seem to feel the leak.

Thanks again as I am still new and learning everyday.

You need to release the snap-ring behind compressor cover to release the cover. The o-ring sits in between the compressor cover and the compressor wheel back plate, you will see when you remove the cover. Be careful not to allow the cover to damage the wheel in the process.
