!Help! Losing loads of coolant- broken down

AndrewSS · 10-09-2023, 08:11 PM

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!

Did the plug on #7, or any plugs, have coolant on it/them when you pulled it/them out?

AndrewSS · 10-09-2023, 08:24 PM

No they didn’t.

I’d start with a cooling system pressure test.

I did a carbon test on the coolant reservoir it was positive

Pull the heads and have them checked for cracks and resurfaced. Then reinstall with new head gaskets.

white smoke out the exhaust is usually signs of head gasket failure. Either way, take the car to someone that works on heads and engines before there are further issues or you risk damaging the engine further as coolant travels to areas it should not be in.

If coolant is going to other places. Check the oil and see if it's discolored. Could be a gasket issue with the white smoke. Compression test? Maybe a bad valve seal? Some early LT's had valve spring issues, but I think that was in 2020.

Blown head gasket or cracked head maybe. Getting coolant in your cylinders, reason for white smoke.

Let us know what the problem specifically is I'm always interested in hearing about things that break to watch out for. Is your car stock?

Will do! It has a cold air intake and 2ed cats cut out.

Failed head gasket or a hole in an expensive metal part where it doesn't belong.
