No, it will not cause the engine to knock.
loose or missing torque converter bolt to the flywheel
Possibly the lock-up torque converter solenoid is sticking. Disconnect the wire to the lockup converter.
No. Sounds like the catalytic converter is going bad. Rotten egg smell is a sign
I found in a google search 15ftlbs torque for the knock sensor.
No it will not.
Lifters dont really knock, they chatter. You may have a bigger problem.
piston slap. very common
A spun--Bad rod bearing. NO OIL PRESSURE.
it can still knock and work but it wont last to long..its cylinder knock that's all.... your going to need a new motor!
yes when it is not working properly
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.
There is no torque specs. on that. Just make sure it's tight and be carefull not to brake it off.
