Freeing up a stuck valve without having to tear the engine down - Duration: 11:38. by dawino6260 47,255 ... 2005 scion tc enginetap/knock.

there can be a crack on exhaust manifold or on eghaust muffler.

humming could be the motor turning round but not engaging with the flywheel. you can check this by hitting the starter with a spanner a few times. if it starts up after you have a sticking solenoid. had to do this a few times my self to get engine started. replace starter as soon as possible if it works. usually happens if you not driven car for awhile.. or you do a lot of starting and small trips.

1. Brake booster diaphragm may be torn.
2. Tie rod ends may be failing.
3. Likely lifter noise. Change to better oil and oil filter.
4. Hood stops need adjusting.

You need a mechanic.

sounds like the idle air control valve it is on the throttlebody area

Were the rear muffler tailpipe hangers checked for being broken or missing? even Engine mounts will cause this and because it does making a left turn you would want to check out the right rear one especially and of course if needed replace all of them...also meaning the hangers for the exhaust system..

have your alternator tested. if you have a speaker system, check the wiring and grounds. check the power cable and connection to the alternator.

Left hand side (if facing it), behind distributor, above oil fill.

Sounds like you may need a motor, or something in/on transmission. What is your oil pressure like?
