1991 Nissan Micra Timing Problems

Air Conditioning


Dear sir:
Cars timing is not responding with compression.
Timing belt was removed and replaced.
When startng it had a clinking sound. I imediately shut it off. Now it only wines without compression at the no:1 cylinder. Do I check valves?

I also reset the timing, but continued to have wining without compression.

Any info will be appreciated!!!
