Leak Testing?
I have seen plumbers testing pipes.
An engine is an intake pipe connected to an exhaust pipe with interesting bits in between.
A forced induction system should not leak pressure.
Can we test an intake track the way plumbers do; with two plugs and air pressure?
My thought:
Remove throttle body and disconnect the midpipe connection to the exhaust manifold.
Insert the plumbers test plugs on both ends and inflate them, then pressure the "pipe" to about 5 PSI and listen for leaks.
I think any intake leaks would be obvious; but would the test break other things?
Any bad fuel injector grommet or a gasket leak would show.
