Crank/Cam alignment

I had the timing belt fail (less than two years old- Ever Green brand). After opening up the cover, I can find no apparent reason for the failure...other than it being a crappy belt. When the belt broke, the engine died, so I'm hoping there was not valve to piston happened while coasting at very low speed. Is there an easy way to tell if there was damage without removing the head?

The FSM states to not turn the cam or crank independently of each other, however I need to align the "E" Dot on the cam gear and the Dot on the crank with the "arrow" I need to turn the gears independently of each other. Is this a potential problem?

The 16v is not interference.

I hear you, and i dont even have a G16B and never had a timing catastrofe in my +40 years of wrenching, but this is a FSM paragraph that many have seen:

"After timing belt is removed, never turn crankshaft and camshaft independently more than such an extent as shown in figure." (90 deg either side of the alignment marks) "If turned, interference may occur among piston and valves, and parts related to piston and valves may be damaged."

Thats why i added ASFAIK...

so you say its simply a carry over text from the car applications that have more compression? or is it because some actual personal experiecne with snapping a belt and living to tell the tale?
In the 30 years of the 16v Tracker, Sidekick, Vitara, etc., and the myriad of forums that are involved with these trucks, as well as the number of times timing belts have broken at speed with the 16v, there has not been one instance anywhere, where there has been engine damage. The 16v Suzuki CARS are interference. The trucks are not. Of course, a rule of thumb is to treat all vehicles as though they are interference.
Considering that I believe the compression in the new engine would have been somewhere around 199psi, your numbers look very good.
