That middle bolt looks suspicious.
What reasoning made you think it was burning coolant? sweet smell and disappearing coolant? Did you see any coolant building up anywhere when you were disassembling?

While steaming coolant out exhaust is typically sweet-smelling, burning coolant in combustion-chambers is extremely caustic and burns eyes.
Was there any coolant in either combustion-chamber sitting on top of pistons when you disassembled? Did you do compression-test on engine before taking apart? |

it was sweet smelling, no antifreeze found anywhere. I dont have the tools for a compression test
i ordered a gasket for 35$ CAD it should arrive next week.

So i replaced the cylinder base and head gaskets. That solved the issue.
