Potential boost leak???

[-DSM2NR-]

I did a boost leak test and there's air escaping from the head fuel inlet holes where the injectors plug in. Is this a boost leak? I've heard people say it's normal and not a boost leak but I think otherwise.
I did replace the Injector O rings but I guess that didn't help.
So, should I put some gasket maker silicone on the holes to seal them or should I leave it the way it is?

It is a boost leak. When people say that it is normal they probably mean it is a normal boost leak spoty.

Replace the injector insulators. This will cure your problem. Don't use any RTV.

I agree with tommiman. Mine was leaking there too. Went to the dealer, got new seals, and no more leaks. These seals should be very squishy...if they are like a hard plastic, then they are shot.

hmmm... I changed the insulators recently... they were from the dealer and were ceramic like... I think you're referring to the o-rings
