I took my 2000 Outback to my mechanic to do the 100K timing belt and water pump replacement, but my mechanic is stuck. He replaced the timing belt following instructions from AllData.com and some other resources and seems to have everything lined up. However, when he tries to turn the motor by hand, the #3 rocker gets locked up. Confusing the situation, if he loosens up the rocker bolts a bit it turns OK.
He has taken off the heads and is sending those to the machine shop to do some more testing (to see if any of the valves, stems, etc are bent). Everything looks fine using a visual check, so I suspect the machine shop will also say they're OK. Then he'll put the heads back on and we'll be stuck again.
HAS ANYONE EVER HAD A SIMILAR PROBLEM???
I believe my car has the 2.5L EJ251 SOHC engine.
