Length of OCI after head gasket replacement ?

[craigq]

How long of an OCI should I run before changing the oil after a head gasket replacement ? As a result of the oil analysis here : UOA Mobil1 5W30, 3686miles, 2003 Nissan Sentra GXE
the dealership inspected the engine and the head gasket was replaced under warranty. Part of the repair was an oil/filter change. What would be a reasonable OCI before I should change this oil/filter ? Is it worth it to get it a UOA done on it ?

Thanks for your assistance !

I'd run it 1000 miles, change it. Go another 3k and do that oil change with a UOA to make sure your good to go.

You'll have increased SI but not to worry.

I'd just stick with what you were doing and watch the coolant level like a hawk to ensure that the new gasket fixed the problem.

I would give it 1 or 2 short (around 1000 mile) OCI's just to be safe. Good catch on the leak with the UOA. Glad it worked out.
