Default Intake manifold gasket blew and...

While performing DIY leak check, I ended up blowing the intake manifold at around 16psi. Car was tuned for 19psi, but has been unable to hit the target boost for a few weeks. Turned out that it was due to blown intake manifold gasket on passenger side.

Felt great in a way that I was able to pinpoint to source of leak after weeks of troubleshooting

However, here is where problem started.

After putting everything together, I fired her up and car drove just fine although I heard this clicking noise coming from passenger side (click - click - click) which sounded more like brake pad rubbing against rotor. I pulled over the car and noticed car is leaking oil from underneath the engine. Small puddle of oil, which stopped after shutting the engine off.

It was too dark to further inspect and didn't feel like taking a chance by driving as is. I ended up taking my car to my buddy's shop (within 1 mile distance) after adding 1qt of oil to have him inspect the car.

Can anyone help troubleshoot this problem? I cannot seem to figure out how performing leak check (~16-17PSI) could result in oil leak...

Thanks in advance for your help and time!

PS: leak check was performed by connecting DIY leak checker directly to throttle body

Do you know where the oil leak is coming from? It should be easy to tell where if its leaking bad enough to puddle up in such a small amount of time. This might not have anything to do with your leaking intake manifold gasket or you doing a boost leak test (frankly I don't see how it could). Did you do anything else while you were working on the car? Maybe an oil change and accidentally left the old filter gasket in place?

I'm not sure that anyone on here will be able to give you much useful information in this case, your best bet will be to hear what your buddy finds out looking at your car. In any case, good luck to ya!

Looks like my car has blown cam seal...

I am still trying to understand how leak test @ 16psi would induce blown cam seal.

Check your PCV vavle. If it is not happy, or stuck open, you just pressurized your crank case. IIRC, there are at least 2 check valves in the system to prevent that, one that diverts the PCV system from the intake manifold to the turbo inlet during boost, and the PCV valve itself.

It's real common. You aren't the first person to do it, if it makes you feel any better. You pressurized the crankcase, which normally doesn't get that kind of pressure. Next time crack the oil cap open when boost leak checking.
