If the valves were bent,there would be a loss of compression and the engine wouldn't run.But the knocking is not a good sign.Avoid running this until set correctly.
Most people get the timing wrong in Honda cambelt replacements as they run anticlockwise,not clockwise as all other manufacturers.
Ensure that you are lining up all marks precisely as the angle you can see some on distorts your vision.I often use a small dental mirror to get in close and a white marker pen to highlight the correct markings and a straight line across the belt to correct any error from where I can see from.
Also on the model that has the second small belt onto the balance shaft,it takes some patience to set marks well(ensure that this balance shaft is on the correct rotation and align)
And remember as you hand crank the engine around two full turns to check for all marks to align again.The engine turns anti clock wise.
Any more troubles,get back with your engine code and I can post diagram and instructions.
Hope this helps.

3.5 timing chain noise one sec on cold start

Oil pressure pushes the tensioner foot up against the chain. When the rubber face wears down it will come to the end of it's travel and then stop. High mile engines don't produce a lot of pressure on a cold start, so look at the pressure regulator in the oil pump and replace the timing chain tensioner.

Low end knocking noise; 220K miles;

sounds like a bad rod bearing. if auto trans put in drive hold brake firmly with left foot gently push on gas pedal with right foot if knocking increases with engine rpms bad rod bearing time for engine rebuild

My 2004 chevy trailblazer is knocking

could be a big end or main bearing but there are a few simple checks that can be done first
1--have the oil pressure checked using a mechanical gauge
if there is a bad bearing there will be low pressure at idle
2 --check the exhaust for smoke under load
if there is a bad bearing , the escaping oil will overload the oil ring and produce smoke
( if smoke comes after idling at lights and on taking off that is valve stem seals)
3--- run the fault codes and check for knock sensor problems
the noise could be detonation under load from lean fuel mixture or incorrect timing
4---check the ignition timing
5-- run the engine when it is knocking and remove a plug wire and see if the knocking stops
bearings will stop knocking if there is no combustion to place load on the crankshaft
That will also indicate which big end you have to check if you have to pull the sump
Too far advanced will cause the pistons to slap the cylinder walls hard for too far advanced ignition
you statement that the noise goes after 40 indicates that it is not a bearing as the high the rpm the louder the noise
taking the foot off the pedal indicates detonation
lastly if all the checks prove good , you could always have the sump removed and check each big end and main individually for damage
sometimes a failing cam chain if fitted ( no motor identified) will knock as the chain hits the timing cover

Knocking top of engine

Make, Model, engine type, year etc. please.

It could be a timing chain issue, or a balance shaft issue, a lubrication/oil pump issue, a worn camshaft issue, or any combination of those things.
It will help greatly if we know which model the car is as some models may have common faults associated with them.

Timing chain 96 maxima broke

Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Maxima is 60,000 miles.2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.3 Release the pressure in the fuel system, drain the cooling system and disengage the negative battery cable. 4 Undo the upper radiator hose, engine drive belts, power steering pulley and pump with bracket, air duct, passenger front wheel and engine side and undercovers, front exhaust pipe, cylinder head front mounting bracket and head cover, rocker cover, distributor and distributor cap and spark plugs.5 Take off the intake manifold support and move the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.6 Disconnect the cylinder head front cover, water pump pulley, thermostat housing, upper and lower tensioner and slack side timing chain guide, idler sprocket bolt, camshaft sprocket bolts, sprockets, mounting caps and camshafts. 7 Disengage the cylinder head with the manifolds, idler sprocket shaft, upper timing chain, center crossmember, oil pan and strainer assembly, crankshaft pulley, engine front mount and bracket and the front timing cover. Remove the oil seal and unfasten the timing chain cover, idler and crankshaft sprockets and the oil pump drive spacer. 8 Unfasten the timing chain guide. install Your Timing Chain 1 Grease the oil seal lip with engine oil and place it in the front cover. Verify that the No. 1 piston is at "Top Dead Center" (TDC) of the compression stroke. 2 Reconnect the crankshaft sprocket (marks should point toward the engine's front), oil pump drive spacer and timing chain guide and the lower timing chain. Line up all mating marks.3 Hook up the crankshaft sprocket and pulley, lower timing chain, front cover assembly, engine mount and front mounting bracket, oil strainer and pan assembly and center crossmember.4 Reattach the upper timing chain, idler sprocket (to the back side), cylinder head assembly, idler sprocket bolt and exhaust and intake camshafts. Place the intake camshaft knock pin at 9 o'clock and the exhaust pin at noon. Connect the camshaft bearing caps and distributor brackets and secure all mounting bolts.5 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.6 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.7 Refill the cooling system. Hook up the negative battery cable and any other disconnected items. Start the engine and look for leaks.

Car running hot after changing the water pump and the car will cut off if i dont keep my foot on the gas ,i had too remove the timing chain too get too the water pump

after water pump did you burp air from system? as for the timing chain did you put the old worn out timing chain in the same postion you taken it off? and you sure you didnt knock off a vacuum hose somewhere. to check that while engine running spray choke cleaner along hoses if idle rises you near the leak ,BE CAREFUL CHOKE CLEANER IS FLAMABLE

Oil pressure gauge is zeroed out (0); oil is fine; engine started to knock (valve knocking). Help!! Engine was never low on oil.

Oil was check with a dipstick?then you only check its volume,here the real check you lost pressure.The oil pump supplies oil to valves to timing chain but is not the device that creates pressure, pressure is created by the cranksahft and its main bearing, if the oil pump fails then the crankshaft cannot create the needed pressure ,is the pan hit? Do not turn this on no more, youll need to get it inspected, if you run ir it will just freeze up. tow it to a repair area,

sorry caps:
Before you condemn the engine remove the oil pressure switch and screw in a hand held mechanical oil pressure gauge just to verify your pressure readings.
How old is the oil and what weight are you using in it?
Is the iol level full and how often do you change it...I recommend every 2500-3000 miles oil and filter.
What type of filter is being used is it a purolator or any name brand?
try raising the viscosity perhaps to a high detergent 10 w 40 weight and see if anything changesDid you use the old oil pump from the old engine? If so its possible its worn and should be replaced soon, also did you use the old pick up tube and screen, if so was it cleaned out real good.
No knocks etc. is almost an indication of a false oil pressure gauge reading, ior the oil pump is starting to develope wear in its gear/housing clearances, what was the oil pressure just prior to what you have noticed lately.
