I'm having a hang-up with a 255 '06 wrx build right now and could use some insight from some more experienced builders. And my math double checked.
Long story made short... Stock piston blew apart from pre-ignition. The piston kissed the head bending 3 valves and the plug. Head was sent off to the machine shop to be welded and rebuilt. They went ahead and did a full valve job without being told too, and cut the seats pretty deep & did nothing to compensate
. The clearances are completely shot now.
Before I post up a chart of measurements... what should the proper lash settings be for 06+ avcs wrx?
I went ahead and calculated what size lifters I need if they are indeed .008/.010". If those are the proper clearances, even the 468 lifter won't work.
