Just did it and in 60 seconds it dropped 300psi

if it is not a leaky injector then it can highly likely valve guide seals and not leaky fuel.

if it cannot be found, the pulling the exhaust manifold away from the cylinder head and cranking it up to see what cylinder smokes.

Ok thank you, I am going to check the injectors then that and report back. Thanks again
