Air In Coolant ???

    A while back I did an intake gasket on a 5.7 TBI. Went thru everything changing hoses, waterpump, radiator cap etc. I'm hearing what appears to be air gurgling in the heater core upon accelaration from a dead stop. I had a small leak @ the t-stat housing I fixed. Pressurized the system & no leaks found. The new rad cap ck'd out fine as well. When I had the intake gasket leak & coolant was low, it gurgled but stopped when I added coolant. No it gurgles all the time... I'm stumped !!!

    Possible faulty head gasket or hole in or cracked cylinder wall? I am not a Chevy man but maybe the intake gasket could cause it too if not just so. Have you checked your radiator for bubbling with exhaust odor?

    Checked that, definetly no exhaust bubbling.

    I'm not sure if this would do it, but could you have reversed which hose went to which pipe on the heater core?

    Definetly not. It is totally foolproof.
