Bad injector causes blown cylinder???

My friends turbo accord (f22b2) was running rough and I did a compression test.

the results were 65, 200, 200, 200. After putting gear oil in the low cylinder, the compression raies to 160. This hints at bad rings.

Has anyone had this happen by the cause of a bad injector. The injector clicks fine but durring installation had issues with getting it to seat properly (dsm 450's)

if there was a manifold vacuum/ boost leak at the injector maybe. It would cause wrong air/fuel ratio at that cylider

yep, but if the injector wasnt working at all (meaning no fuel) it wouldnt cause a problem, just a 3cylinder motor (probably sound similar to a WRX), no fuel means NO detonation, so only if that injector was leaking boost/fuel, or clogged not allowing the proper amount of fuel would it hurt anything besides performance.
