IF you did not keep that rocker gear and rockers together as units then the noise may be from the wear on the ends of the rockers not matching the wear for the valve ends. If you fitted 1 new valve and did not grind the rocker arm wear out that may be the ticking noise

sounds like your timing belt may have slipped or snapped a ceased timing belt adjuster could cause this check your timing belt and adjuster and all belt adjustment pulleys before you fix the valves otherwise its bound to happen againalso make sure your engine oil is full

SOURCE: loud knocking or tapping sound when engine is cold

Take our oil pan off from under your car and there should be 4 to 5 covers over a rod bearing. wiggle each one of them and find out which one is loose. take that cover off of the one that is wiggling and get the rod bearing out. order a new one from auto zone and replace it. The knocking in your motor can end up where you will need a whole new motor. so get it done before its to late.

SOURCE: Cracked Cylinder Head

I'd say moderately difficult: here are the instructions for replacing the head on a 2001 Jeep Cherokee Sport with 4.0 L engine:

REMOVAL & INSTALLATION 4.0L Engines

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the cooling system.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Crankcase Ventilation (CCV) hoses
    • Air cleaner assembly
    • Accelerator cable
    • Cruise control cable, if equipped
    • Transmission cable, if equipped
    • Control cable bracket
    • Valve cover
    NOTE: Keep valvetrain components in order for reassembly.
    • Rocker arms
    • Pushrods
    • Accessory drive belt
    • A/C compressor and bracket, if equipped
    • Power steering pump and bracket, if equipped
    • Fuel line
    • Combination manifold
    • Thermostat housing coolant hoses
    • Spark plugs
    • Engine Coolant Temperature (ECT) sensor connector
    • Cylinder head
    To install: WARNING
    Cylinder head bolts may only be reused one time. If reusing a cylinder head bolt, place a paint mark on the bolt after installation. If a cylinder head bolt has a paint mark, discard it and use a new bolt. NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
  4. Install the cylinder head with a new gasket. Coat the threads of bolt No. 11 with Loctite® F 592 sealant. CAUTION
    During the final tightening sequence, bolt No. 11 will be tightened to a lower torque value than the rest of the bolts. Do not overtighten bolt No. 11.
  5. Tighten the cylinder head bolts, in sequence, as follows:
    1. Step 1: 22 ft. lbs. (30 Nm)
    2. Step 2: 45 ft. lbs. (61 Nm)
    3. Step 3: 45 ft. lbs. (61 Nm)
    4. Step 4: Bolts 1–10 to 110 ft. lbs. (149 Nm)
    5. Step 5: Bolt 11 to 100 ft. lbs. (136 Nm)
    6. Step 6: Bolts 12–14 to 110 ft. lbs. (149 Nm)
    7. Step 7: Repeat steps 4, 5 and 6
  6. Install or connect the following:
    • ECT sensor connector
    • Spark plugs
    • Thermostat housing coolant hoses
    • Combination manifold
    • Fuel line
    • Power steering pump and bracket, if equipped
    • A/C compressor and bracket, if equipped
    • Accessory drive belt
    • Pushrods and rocker arms in their original positions
    • Valve cover
    • Control cable bracket
    • Transmission cable, if equipped
    • Cruise control cable, if equipped
    • Accelerator cable
    • Air cleaner assembly
    • CCV hoses
    • Negative battery cable
  7. Fill the cooling system.
  8. Start the engine and check for leaks.

Hi my partner has a 2011 meriva a 1.7 cdti management light came on and car lost all compression in number 4 cylinder glow plug looks damaged or seriously burnt any ideas


no compression and damaged glow plug can be debris in cylinder [broken valve piece of glow plug ]damaged piston or valves will need to pull the head off or use a scope to see what damage is in the cylinder but you will have to pull head any way to remove and check for debris and condition of cylinder wall --when removing the valve cover will be able to inspect the valves and rockers on cylinder 4

Trying to replace broken timing belt. Trying to set #1 cyl. to TDC manually. no compression reading on 1 &4, readings on 2 & 3. What could cause this?? HELP!!


Hole in the piston crown is the worst Charles, but let's not be pessimistic :>(

More likely valves open. At TDC firing stroke both inlet and exhaust valves should be closed. The flat, low part of the cam should be on the followers. So 1 and 4 have valves open, 2 and 3 are closed. If you turn the cam 180 degrees, you should have compression on 1 and 4 and no compression on 2 and 3.

The other thing though, is that when the timing belt breaks, the valves are often in the wrong place at the wrong time and can often meet the piston head on. This can bend the valves. or damage the piston. The normal advice is to remove the cylinder head to check, and then service the valves whilst you have it apart.

A job like this, you need a workshop manual.

What would cause no compression what so ever,we have replaced the head gasket.


The Kia engine has two overhead camshafts that have to be properly aligned when installing the cylinder head. If you didn't get the timing marks on the cam pulleys as well as the crankshaft pulley lined up the valves will hit the pistons the first time you crank it over. If the valves hit the pistons, they will bend and no longer seal [no compression]. For instance, if the timing belt breaks while the engine is running here is a picture of the result [also no compression]:

From the next picture you can see how close the valves are to the pistons:

If the timing belt broke is the motor gone


I don't know where it would have gone to...
.
Just kidding.

On a more serious note: Your engine is an "Interference engine". What this means is that if the timing belt breaks, one or more of the valves will get hit by the pistons causing severe engine damage. The cylinders can be leak tested by removing the cams and putting compressed air into the spark plug holes to help assess the damage. In most cases, it can be fixed by removing the cylinder head and replacing a couple valves. In more severe cases, the pistons, the cylinder walls, or the cylinder heads can be badly damaged. It will be impossible to tell you exactly what needs to be done without some testing and disassembly. It is not likely to be cheap at any rate. It's more like if it is going to be expensive or is it going to be REALLY expensive?

1997 Neon- DOHC. My timing belt broke or came loose. I am told that this engine is an "interference" engine. Before I repair the bad water pump and replace the timing belt,,how can I be sure...


DON'T KNOW HOW MANY MILES BUT CRYSLER PRODUCT ARE KNOWN FOR BENDING THE VALVES
WHEN THE TIMING BELT BREAKS, YOU WON'T KNOW HOW BAD THE DAMAGE IS UNTILL YOU PULL THE HEADS. NEW VALVES AND CHECKING THE HEAD COULD RUN UP AROUND 800 DOLLARS WITH OUT REPLACING THE HEAD. A NEW HEAD COMPLETE 1,700 DOLLARS THESE ARE JUST ESTIMENTS NOT A GOOD SIGN, I'LL LET YOU MAKE THE CALL 2,000 REPAIR VERSES 20,00 NEW CAR

How far off timing can be before harm is done


Timing is not likely to be a problem here, but the broken pieces of insulator sure could be. You should plan on removing the cylinder head for inspection and any repair. The porcelain insulator is hard enough to puncture a piston and bend valves. Without the interior insulator, the center electrode would have been glowing red hot. The insulator could have broken due to excess heat from a weak injector, or excess tightening of the plug when installed. If a timing problem, then it would be probable that all plugs were overheating. Hope this helps!

If the timing belt breaks does this shear or bend the valves on a 2000 deawoo lanos?


All Daewoo Engines are interference fit Engines. Which means that if the timing belt rips while the engine is running the pistons will hit and bend the valves and you will have to get new valves and possibly a new cylinder head. Worst case scenario you will also have to get a new engine block if for some reason chunks or pieces of valve, piston or cylinder head damaged the cylinder bore and cracked the block while things were moving around. Daewoo Timing belts are recommended to be replaced at 60,000 miles but it is best to replace them before 60k as some people have had their timing belts break on them as soon as 61,000 miles.

My timing belt in my 98 Daewoo Lanos snapped recently and the mechanic i took it to told me there was no need to check to see if there was any damage inside the engine because daewoo motors always drop...


yes they bend valves
head needs to come off and valves will need replacing
this can be repaired
timming belts on these should be replaced every 60,000km
