Yea the intake leak looked excessive, for years I've thought it was a rocker leak kept replacing rocker gaskets but still leaking what looked like to be oil, but with the injectors out i can see the rocker is sealed.

I have no maf on my mr2 instead i have a map sensor but if the manifold is leaking then surely it would give false readings to the map, the map is definitely working as i tested it by probing a volt meter across the ecu as it says in bgb and vacuum tested it the readings i get all match what's in the bgb, the map wiring is also putting out correct voltage
