For the Doser pipe,.. I remove the pipe that goes down towards the DPF,.. Then I stuff this inside, and inflate it to 35-PSI.

For the intake, I remove the air filter and stuff one of these (depends on size of pipe) into the pipe, inflating it to 35-PSI ...

or...

I use a bicycle pump to inflate them.

After I plug the entire engine,.. I remove the turbo inlet temp sensor and have an adapter I made to put about 10-20 PSI of air (with a really good regulator and pressure gauge).


I listen for leaks (it needs to be fairly quiet around the truck),.. and use soapy water on every pipe and gasket, the CAC, and a lot of other components too. It is extremely effective in finding fuel mileage loss and boost leak problems... Even if they are minor.

I also use this with my EVAP machine sometimes and that is very effective too.

You would be surprised at the places that engines will leak, such as a bad air compressor head leaking boost into the crank case, etc. -- I even found a bad EGR cooler once this way that was putting pressure into the coolant system.

======

I have always been able to find leaks with the tools I mentioned above, but in your case though,.. you might want to have something made that will allow for even higher pressures to be used.

Thanks Rawze for the info. I have found this online http://otrperformance.com/product/volvo-...tester-xl/
Let me know if you think this will do the trick. Oh and I wanted to mention that I only have EGR (No DPF Thank god).
