Loud knocking coming from lower timing cover area 1995 toyota camry 2.2


I do think that loose key and keyway could cause the knock. It would also explain the loss of power, due to the engine timing not being spot on.
A knocking big end or main bearing would not improve at higher revs, it would get worse.

Act soon before the keyway in the crankshaft itself is too badly damaged, by removing the crankshaft pulley, lower timing belt cover, and belt guide. You can then get a precise idea of what exactly is worn. This may assist

You may actually have to find an oversize key, for a neat fit in the crankshaft. It may be necessary to file or grind it to fit. Engineering supply houses stock them, eg

This sounds like the crankshaft vibration dampener is coming apart it is what the pulley that the belt runs over is bolted to, they knock like crazy, common issue on some Ford models.

Engine has a whirring noise, like a dry bearing on a pulley.assuming its a pulley because it gets louder when revving engine.


The noise u hear is most likely coming from a defective power steering pump or accessory belt idler pulley, to make sure use a 1/2" wooden dowel or old broom stick and hold it against the area where u hear the noise to isolate the exact location.

Loud knocking coming from the bottom end and now loss of power sludge build up i have changed oil normal every 2500-3000 miles with synthetic and slick fifty.


the engine probably has a bad bearing in it.oil sludge can be caused by short trip driving,overheating,pluged crank case vent or pcv system not working.the power loss due to the computer retarding ignition timeing due to the knock sensor producing a signal from the engine knock.regardless an ongine ocerhaul or replacement is neede.
but first make sure that the bell housing bolts,torque converter bolts are all tight.
make sure the knock isnt from the catalytic converter
check for dents in the oil pan
check engine accessorys for noise such as water pump.power steering pump,alternator,a/c compressor.and all attachment bolts

Bad leak, dont know if its water pump or thermostat


sounds like your water pump gasket has a hairline crack in it and as engine warms it expands and leaks more

4.3 vortec engine , engine noise, knocking or tapping on top of engine, not when cold , but starts noise when it heats up, and gets louder as it gets hotter and hotter!!! Sounds like noise is in the center...


The knocking or ticking is going to determine if it is in the top end, lifters, push-rod or rocker arm issue or the bottom end that would include pistons or bearings.
If it is a ticking noise, it will more than likely be a valve train issue.
If a knocking noise, piston or crankshaft related problem.

Attached is a web site that you can listen to a piston slap which is a known issue for your 4.3.
Listen to the noise and see if it sounds similar to your problem. A piston slap will generally sound as though it is coming from the central area of the engine.
Listen to the recording and let me know.
