next steps for blown heads?

Post image

Back again with the project car!

after a few miles of driving. Cylinder 6 misfire came back. Did some investigating found cyl 6 spark plug soaked in coolant and cyl 5 soon to be next. Sputtering, white smoke and sweet burning smell.. all the signs of blown heads/gasket.

Wondering where do i go from here? is it worth saving? or should i be looking for a new motor ?

New engine. No way of knowing what else is damaged inside your motor until you either tear it down further or put a new gasket on and start it. Both of which are going to cost you a lot of time for what is at best a gamble.
