those cylinders are all on one side of the engine.
you may have a bad intake or head gasket.
Thanks, will a compression test help tell me which 1?
a compression test will help you find out if it's a head gasket failure.
a smoke test would reveal intake gasket leak. Or just spraying some start fluid around it.
Ok thanks for the help!
