Just replaced the timing belt in my 1993 Maxima SOHC V6. This is an
INTERFERENCE engine.
I know for a fact that the belt was on wrong at one point. I turned it by
hand, and then with the starter. I can't tell in either case that the
valves were hitting anything.
I have since learned enough timing belt karate to get the bloody thing on
with all reference marks where they seem like they should be.
NO COMPRESSION on any of the three cylinders I checked, with a gauge.
Before this, the cylinders would just about blow the hanging spark plug
wire out of its respective hole on the compression stroke.
Did I bend the valves by cranking it over with the starter, after manually
cranking it?
Thanks for looking!

Yep they sure are.

They probably did...

Sounds like it. Check the comp on a bank that the valve cover is easy to get
off. If it has none, remove the cover. If the rockers are "sloppy" with
lots of clearance, you bent the valves.

true to bending the valves if you have no compression and the cam
followers are loose. Time to pull the heads and have the valves gone
through. You might get lucky and not have hosed the cams...
