Cold engine knock after timing belt and water pump replaced

knocking is a big thing, its a cry for help.
can be minor to horrific
knocking parked? or only driving.
in neutal or park?
knocking hot block, or cold block or both? at what RPM>/
only real oil pressure gauge works, not the idiot lamp
when the lamp comes on at 3-5psi, the war was lost.
my 96 makes 55psi cold just cranking, want a video of that?
find the knocking first.

if can ,be knocked , parked.?
id check oil pressure. real.
use a $5 stethoscope. find it.
drop all belts. to see if an accessory device knocks. (5min test max cold to start, yes, water pump dead)
PS/AC/ALT dead too.
still knock>
listen at valve cover. coming from there.
is the timing belt is old over 60k thy all shard and some knock load hitting that cover, it a for sure thing, skipping the 60k mile service point,
exhast header collerctor fange gasket , bad, allowing bang band bang as the 2 flanges pound themselves to death.
the top of the engine, see induction pips. (AIR) those mounts for sure can bang away, bolts missing.

knocking:
1 overheated the engine so bad its pinging? knocks up hills?
2: say exaclty when and not you get the knocks.

Hope this help.

jack up on stands, remove LF wheel and water shield. disconnect battery, buy a crankshaft pulley holding tool from OTC, swing p.s. reservoir out of the way, remove both accesory belts, front motor mount, valve cover, dipstick and tube, crank pulley, timing belt cover, set engine at TDC #1 (align marks), remove nut on tensioner shaft to loosen both belts, remove the belts and tensioners (replace all), replace water pump NOW, install timing pulley, reinstall spring (use dipstick tube bolt to hold back the timing pulley with the slot in the bracket on the pulley until the belt is installed), install balance shaft belt, pulley and spring, once tensioned rotate engine once and retension by loosening the nut and retightening. Make sure the marks are still lined up, and reinstall everything. New valve cover gasket set with silicone in the corners. fill with coolant and bleed system once finished. it is a good idea to also change all the oil seals while you are in there.

Sometimes you must install the timing cover temporarily with the crank pulley to ensure you are at true Top Dead Center line up the notch on the pulley with the pointer on the timing belt cover or pointer on crankshaft cover I had a problem with a dual cam Honda in which the marks on the engine block where slightly off. you must ensure that both intake valves and exhaust valves are shut one cylinder #1 by turning the cams in the appropriate direction, from your description of the situation it sounds like when it runs poorley it is off by one tooth, when you move forward a tooth it runs but poorly make sure you are moving both cams if equipped with dual cam, both cams should be in the exact same visual location in other words all valves completly shut, be careful not to move lower shaft after lining up the crank pulley to cover pointer marks, after resetting turn the engine over two full turns then recheck all markers.

Replaced the timing belt and Tensioner and it works great now.

1. Let me know if you cannot see diagrams(happens sometimes) or if you have any questions

Just to make sure. I assume that you are seeing coolant leakage from around the water pump assembly.

1. 
   
2. Disconnect the negative battery cable.
3. Place fender covers on the aprons.
4. Drain the cooling system.
5. Remove the accessory drive belts.
6. Remove the timing belt cover.
7. Use a wrench on the crankshaft pulley to rotate the engine so No. 1 piston is on TDC of the compression stroke.

Turn the engine only in the direction of normal rotation. Backward rotation will cause the timing belt to slip or lose teeth.

1. Loosen the belt tensioner attaching bolts, then secure the tensioner over as far as possible.
2. Pull the belt from the camshaft, tensioner, and water pump sprocket. Do not remove it from, or allow it to change its position on, the crankshaft sprocket.

WARNINGDo not rotate the engine with the timing belt removed or serious engine damage could occur. The 1.3L and 1.6L engines are of the "interference type," meaning it is possible for the valves to contact the pistons if their reciprocation is not carefully timed and controlled. An engine allowed to spin freely without the timing belt could bend valves and scuff pistons almost instantly.

1. Remove the camshaft sprocket.
2. Remove the rear timing cover stud.
3. Remove the heater return tube hose connection at the water pump inlet tube.
4. Remove the water pump inlet tube fasteners and the inlet tube and gasket.
5. Unfasten the water pump to the cylinder block bolts and remove the water pump and its gasket.

Fig. 1: If equipped, remove the cover from the water pump Fig. 2: Unfasten and remove the heater return tube hose connection at the water pump inlet tube nuts from the studs Fig. 3: Location of the water pump mounting bolts-1.9L engine Fig. 4: After unfastening the water pump retaining bolts, remove the water pump from the engine compartment Fig. 5: If you are reusing the old water pump, remove the gasket ... Fig. 6: ... and carefully clean both of the water pump mating surfaces using a gasket scraperTo install:

1. Make sure the mating surfaces on the pump and the block are clean.
2. Using a new gasket and sealer, install the water pump. Tighten the bolts to 30-40 ft. lbs. (40-55 Nm) on 1981-87 models, or to 15-22 ft. lbs. (20-30 Nm) on 1988-90 models. Make sure the pump impeller is able to turn freely.
3. Install the water pump inlet tube and the inlet tube gasket and fasteners.
4. Install the rear timing cover stud. Install the heater return tube hose connection at the water pump inlet tube.
5. Install the camshaft sprocket.
6. Install the belt from the camshaft, timing belt tensioner, and water pump sprocket.

1. Tighten the belt tensioner attaching bolts, then secure the tensioner over as far as possible.
2. Install the timing belt cover.
3. Install the accessory drive belts.
4. Refill the cooling system and reconnect the negative battery cable.

There are two slots in the valve cover right by the cam shaft sprocket that have to be honda bonded or black rtv. look closely at the valve cover right above the gasket underneath the timing belt cover. Hope that helps.
