I have a misfire in cyldr 3. Coil pack, plug and injector are working properly. Compression test was at 205psi, leak down test was at 13-15% and fuel pressure is at 42psi. I hooked up to our shop scanner and O2 readings, evap are normal.
plugs look like they're running too hot, but are oem ngk.
cyldr 3 plug looks the same with the exception that its moist. I want to say antifreeze, but the substance is not oily nor does it smell like antifreeze and with the leak down test passing i'd like to rule out head gasket. Client stated that the car possibly over heated. Im thinking possibility of a cracked or warped head, but can't confirm without tearing into it. Any thoughts or suggestions are greatly appreciated.
