I believe these are the specs for chain.
20 Link length
Standard: 127-127.4mm
Service Limit: 128.9mm
Check tensioner as it should travel in one direction only. If plunger can go back & forth, it's broken. Also if plunger is not smooth, this will also prevent it from moving and tightening. No need for manual-tensioner as working OEM one does good job. If yours isn't working, just replace with factory unit. Lubricate it with synthetic lithium grease before installing.
Also check chain-guide that tensioner pushes on. If it has excessive wear or is broken, cam-chain tension can't be maintained.
