The 8V engine will not hit pistons to valves
I have a 16V engine that I rotated the piston
to TDC and turned the cam with a wrench, no
piston to valve contact, so I think the 16V engine
is also safe if you break a belt.
There have been some differing compression ratios,
one being 9.1 and the other was 8.9, I don't know if
there were 2 ratios available in different countries, or
if the California model got a lower CR or what the deal
is but if you have a 9.1 CR you could have a problem,
same with any high compression piston, there comes
a valve to piston contact problem when you start bumping
the piston into the combustion chamber.
FWIW the import specs call out 8.9 CR on an 8V
and 9.5 on a 16V both Canadian built
