Sniff test
 

Sniff tested all ok .
But i know its head gasket so should i buy genuine subaru and is e-bay ok ?

considering the engine has 2 come out for this, I'd go for the genuine subaru part.
no point risking a second rate part if it means you may have 2 take the engine out a second time

Gonna go for subaru parts is there anything else i will need to change while im doing this ?
Also do they have stretch bolts on the heads suppose thats more bloody expense or can i reuse the old ones ?
And still looking for all torque wrench settings for heads and so on .
