I notice it only really happens when the car is facing uphill and at idle. As soon as the car engine speed goes up it goes back down. Now the upper radiator hose seems like it has too much pressure in the hose. Not sure if it's because of my radiator cap since a part of the rubber that goes around the spring part ripped in one area.

Did the head gaskets 3 months ago because I had to change the heads because of bent valves. I had to buy new head gaskets from the dealer. Tstat is about two years old Dealer brand.

I agree, try burping the air pocket again. Fill by the upper hose, and remove the little bleeder screw on the opposite end of the rad to fill from the cap.

 

If your cap is boogered, replace it with an oem unit. The cap is one variable that could be your problem. If it is not holding pressure, some of the coolant bmay be boiling over pushing coolant out, and then you get an air pocket.

How tight of a seal should be with the cap and the neck of the radiator? It seemed tighter then any other Subaru caps I've had in the past and always wondered if it was hurtful.

Wow sorry to read that.  To be honest from the very first post that is what was in the back of my mind that it was HG.

 

So what are you going to do?   Are you going to get it fixed?  Seems like HG technology has come a long way with the MLS gaskets from a number of vendors

I guess you haven't been here long enough.. these are the replacement head gaskets.. it's been almost like 3 years since I last did it.. I suspect the rod bearings was enough to cause the misfire codes and wear whatever part out of spec.. not that I really care.

 

I'm switching to a Ej22 with my ej25d heads on the motor because I'm planning for something in the early spring.. I highty doubt the block can be saved.
