My 2002 Toyota Echo has started to run a bit louder than normal. It sounds as if it is a background growling noise. At idle, the noise is very slight, however, when I get into 2nd and 3rd gear the noise becomes more noticeable. I changed the drive belts on the car the other day with the front of the car up on a ramp. After starting the car back up, the check engine light came on. I hooked up the OBD II reader which gave me a code of P1656. I looked up this code which said it was the oil control valve. The next day, however, the check engine light went out. The noise in the engine is still present though. My question is would the Oil Control Valve code show up because the front of the car was up on the ramp and not allowing oil to the Oil Control Valve. And would this explain why the check engine light went out the following day? Or is this what is causing the engine to run louder and needs to be replaced. Or is it something else altogether?
The oil control valve will not cause the engine to be loud and if you jacked it up you probably cutoff some of the flow to the oil control valve the big problems with these car are the exhaust manifolds had too replace 2 on mine also get your exhaust system checked
YOU GOT IT. I'm sure the oil pressure went low when the car was on ramps causing a CE light. The louder noise poss wrong belt or exhaust leak!?

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

The noise might be oil on the timing belt. The oil leak might be from the oil pump gasket. The oil pump is ran by the timing belt and the leak would saturate the timing belt. Inspect the belt

This code is for your electronic throttle control system it probably needs to be cleaned the butter fly sticks due to build up in side the throttle body clean with tooth brush and emission save throttle body cleaner clear codes and then dissconnect the battery for 3 hours hook back up then go for a short drive stop and go to reset idle control that should take care of this.
