Sons 300m and I need help please!

How many miles on it?
120k. PO showed us / gave us docs where he had it done at 80k so I thought we were safe.
I guess he could have put in some cheap Chino belt in...
Without other great wisdom coming down the pike, I guess I will head home after work and start pulling the front of the motor apart.
Wish there was some way to check the cam timing without tearing it apart.
Inspection ports or some such thing...5 hours of work just to find out there is no problem and they are good doesn't sound fun after a full day of work..
Let's see, Alarm went off at 0430...commute...work @ 0600...off work at 1500...home @ 1600...into the garage...out 5 hours later=2100 if I skip dinner. UGH:wack:
