Seafoam to find exhaust leak?

is seafoam ok to put in the vacuum lines in the intake on diesels? I have an exhaust leak somewhere around the turbo ever since my turbo swap and I cant pin point it. Ive used it in gassers before and it smokes like crazy and you can see the smoke coming out the leak, just wondering if it is any different on diesels?

It would be better to start the truck when it is cold and use a spray bottle with soap in it and just start spraying the seems. Do it when it is cold other wise you will just burn the water off. And use something flat that a friend can force against the exhaust end. I did this when I plugged my down pipe cuz im going to the manifold for egt's.

This is what I would do......and its cheaper than using seafoam.

And pouring seafoam into your vacuum lines won't tell you anything. None of those vacuum lines go back to the manifold like they do on a gasser. There is a mechanical or electric vacuum pump that provides your vacuum. Forced induction engines don't get any manifold vacuum, so they have an external vacuum pump of some kind.
