I hop it is only the head gasket, may be cracked cylinder head.
I made your suggestions and I keep getting bubbling from the radiator openning and if i increase rpm over 2000 I get a small blast from the radiator. Never got heat from heater.
Thank you for your help
THanks for the accept!
If you keep getting air from the cooling system bubbling up, either there is one big air pocket or the head gasket is bad. I would try to bleed the engine a few times before checking for a blown head gasket.
Good luck with everything!
Let me know if you have any further questions!
