2007 Subaru legacy CEL on and CC light blinkinv

The last code you posted was for the idle air control valve. Scan for codes again. The coolant loss is likely a leaking head gasket. Look for other leaks and try some Subaru brand leak additive.

F_o_r Thanks I will have it scan again and will post new codes. My mechanic is suggesting to change the engine, hoping to find a cheaper alternative.

A new engine seems a bit drastic given the information you posted.

By any chance has the timing been checked?

@ford_fanatic87 yes it was replaced about a year ago.

And how long has the issue been going on?

@ford_fanatic87 since this summer on and off i changed the oil control vvt valve and it went away a couple months and started again a couple days ago

Are there any symptoms or just the CEL?

@f_o_r cel light on, cc blinking and tonight when I took my car it felt like the car was having a hard time starting.

Considering that the p0026 and p0028 have to do with the valves being delayed or not opening I wonder if it possibly jumped timing

@ford_fanatic87 and this would causer for the cel to come on? Is it normal that I need to change my timing belt a year after replacing it? (Sorry not a mechanic and trying to figure this all out)

It can cause the valves to be off when opening and closing, which could cause the p0026 and p0028 codes, ordinarily the belts should last about 7-10 years, but if the tensioner isnt set right it could allow room for the timing belt to jump

Ford, this is REALLY unlikely, as jumped timing will result in significant power loss.... Before replacing either (there's one on EACH head) VVT valve you should note that the much more frequent causes of PO026 and PO028 are loss of pressure because of leaking pressure switches mounted atop them (simple $15 problem), or blockages in the oil lines feeding them (trickier, as dirt can clog the lines and be more difficult to clean out). If the pressure switches aren't bleeding then a bottle of oil cleaner-additive added to the motor oil may clear up an obstruction on either or both lines over time. Note that the VVT valves are symmetrical, so you often may need to buy ONE and chase either the left (028) or right (026) code. Bleeding switches are extremely common, with a tell-tale sign of wetness drooling down the engine from the top of the VVT valve. So chase this easy stuff before you go further! Best, Ern
