The best way to remove a stubborn nut or bolt is to heat it up with a torch, even the little propane torch is better than nothing. ifyou can heat it till it is red you can get it off with pliers. If there is no way to get a torch, then you will have to get a chisel and split it to get it off. good luck

My timing belt shredded replaced it and now just doesn't sound right. And one cylinder Is holding 15 pounds less pressure then the others.


you will need to remove the cylinder head because it sounds like you have a bent valve in the cylinder that has less compresion that would make the engine run rough. That cylinders piston has made contact with a valve so the bent valve wont seat properly

Need to remove valve cover on 2000 Camry Toyota


For the four cylinder engine:

  1. Remove and label all electrical wiring, connectors and vacuum hoses necessary to gain removal clearance.
  2. Remove the spark plug wires. Disconnect the PCV hose.
  3. Remove the four nuts and grommets located on top of the cylinder head cover.
  1. Remove the cylinder head cover and the cover gasket from the cylinder head.
  2. Discard the gasket and replace with a new one.
To install:
  1. With a wire brush or gasket scraper, remove all the old gasket material from the cylinder head and the cylinder head cover gasket surfaces.
  2. When the cylinder head surfaces are free and clean, apply beads of sealant to the cylinder head in the locations shown in the accompanying illustrations.
  3. Install the new cylinder head gasket in the cover. Make sure that the gasket seats evenly.
  4. Place the cylinder head cover with the gasket onto the cylinder head.
  5. Install the four grommets and nuts. Uniformly tighten the nuts in several passes to 17 ft. lbs. (23 Nm).
  6. Connect the PCV hose. Connect all removed vacuum hoses, connectors and electrical wiring. Connect the negative battery cable.

If you are sure you have no compression in that cylinder you need to remove the cylinder head and check for a burnt or bent or stuck valve.

BROKEN TIMING BELT- Testing valves, etc for damage- (1997 NEON) I have installed the larger DOHC engine in this car about a year ago. Recently, the timing belt broke. It IS an intermittent engine. I...


Think about this for a moment....You already know you have a few bent valves. Valves are serviced by removing the cylinder head. That single fact tells you that the head needs to come off to do the repair.
Once you remove the head, you will be more able to inspect the remaining valves and piston tops, then with that information, decide if you can rebuild it. A compression test requires spinning the engine and risking further damage.

If you dropped a bolt or nut down the head will it find its way to the oil pan ?


Hello jim slaughter: My name is Roger and I will help with your question. The answer is not likely. You must remove the object before cranking the engine. If you crank the engine over with the object in the cylinder. Major damage will occur. You will impact the piston and cylinder head with the object.If you have aluminumn cylinder heads the object will most likely become implanted in the head and bend valves. It could severly damage the piston and crack the edge of the oil land. If the heads are cast iron. figure bent valves and damaged piston.You will destroy the spark plug also. The best way to remove the object is to remove thhe cylinder head. If this is a late model vehicle you will also need a new set of head bolts. Do not reuse the old bolts. They stretch when tightend and will break. Should you need further help please just ask. Please rate the answer. This way I know it was useful. Thank You for using Fix Ya. Roger

The roller rockers broke. I am not sure why but I need to know how to replace them


You didn't say what kind of car is, but but if they have a hex nut with Allen screw inside it. Remove the nut and screw the screw back. Remove their old rocker and put the new one on. Put the nut on but not too tight. Now turn the motor slowly until the other valve for that cylinder opens. Now a just and nut down. If it's a hydraulic tighten the nut down snug thing go 3/4 turn more. If its mechanical use a feeler gauge and go with the proper clearance. Then tighten the Allen screw back down very tight. Try to figure out what went wrong. Because it could happen again. Remove the push rods and roll them on a flat surface to see if they are straight don't use bent push rods. Then check for spring bind, with the valve all the way open there should be no spring bind use a feeler gauge to check for this. Also look at the rocker to make sure it's not restricted in any way, also no interference with the pushrod. Without seeing it that's about the best I can do. Good luck.

BENT OR BROKEN VALVE


If you are referring to an intake or exhaust valve, cylinder head must be removed (and likely replaced if valve is broken) Also if that's the case, pistons may be badly damaged and not even worth tearing down. If another valve (tire, egr etc, just remove & replace)
