Got 2002 ej25 from wrecking yard. Im doing a leakdowd test because car was in accident and timing belt came off. Ran good at wrecking yard after the belt was put back on. Noticed this sticker on the block. Is it a sticker put on after head gasket repair? Its not anything the wrecking yard did. 

 

Im also looking for verification on leakdown test procedure/results. Testing at 100psi. Timing belt on, rotating crankshaft until top of compression cycle on each cylinder. At 100psi on left guage  I'm getting about 95 psi on right guage.  

yes that's a typical heat marker put on after a headgasket or other major service.

Usually see that sort of thing on rebuilds.

 

Leakdown test looks good at only 5% leak. Some manufacturers specify up to 15% leak as normal. Not sure about Subaru, but 5% is pretty good on any engine.

For a junkyard motor, those are two big positives.

 

Reccomend a new timing kit unless you know the one on there is newish.
