I check the cover multiple times, its tight and sealed, seal is ok too.
I sprayed brake cleaner by the intake and did not find any leaks.
I did not check the Catch can for an air leak. I will look at that tomorrow.
TB hose is tight against the intake and the MAF sensor

The valve seal leak, where would that be located. All my injectors are new and have new seals. Where would I find the valve seal? Do I pull a valve cover, and how do I determine a seal leak on which valve? Thanks Guys. Im not going to let this one beat me. I will order a new seal for the air intake too. I just replaced the seal on the throttle body.
