C112, C118, or C114 would be prime suspects, or even one of the .01 bypasses (C110, C113), since you say the board was mangled by whoever had it last.

all I have is the freq counter in the meter I bought, and its only 4 digits, I can try to get one with a few more. but they may be costly. by this weekend i will have gone over the whole circuit.
That guy turns out, did NOT have a new xtal, and ended refunding me
so if on the odd chance it is bad, I'm not sure what to replace it with.
The bottom of the pcb has white flux residue all over it, not sure WTF type of solder / flux was used, and it is a bitch to get off, but i got a lot off around the osc area, i have no idea if it was causing problems, bit it is ugly..
