CAMARO6 - View Single Post - !Help! Losing loads of coolant- broken down

Hello everyone, I have a 2018 Camaro SS 1LE with 80,XXX miles.
Check engine light came on last week. Ran code, P050D and P0300.
Misfire on number 7. Losing excess amounts of coolant and lots of white smoke out of the exhaust.
First thing I did was swap coils on 6 and 7, no change. Then replaced number 7 injector, no change. Now getting more misfires on all cylinders. Then replaced all injectors, no change. Then replaced all spark plugs and wires, no change. I’ve cleared the codes and they return. Coolant residue found in intake manifold gaskets. No coolant in the oil. Starting to believe this is a head gasket issue.

Has anyone else had a similar experience and can offer advice/help? I’m at a total loss here.
Thanks!
