This is most likely my issue. Been having problems with my 2016 Dodge Dart SXT (2.4L) since Sept 2022. I have 122K miles, ride it to the MAX as I commute a ton. Since the problems started I replaced the following:You have no compression because the valves are not closing.
The vales are not closing because you have air in the Multiair actuators / AKA Multiair Brick
You have to just keep cranking the hell out the engine until the actuators bleed out the air, and fill with oil.
I killed my battery at least 3 times, maybe 4 times, from just cranking it over 2 days.
Eventually the engine will regain compression and sputter back to life.
FYI, I learned about this because I had to completely take apart my engine after getting oil and coolant mixing together from a blown head gasket.
I did not use any special tool either when removing or replacing the multiair actuator / AKA Multiair Brick.
-All four Ignition Coils
-Like 3 hoses
The big issue is still compression, car will not start out the gate. I found that turning the ignition to the RUN position and letting the fuel pump initiate twice. Pressing the gas pedal 3 times and then trying to start it helps it start. Although this is not practical, my next move is taking it to the Dodge dealership and paying a ton to have the Multiair brick replaced.
Any suggestions and or advice helps. This seems to be the best resource on the web, next to YOUTUBE.
