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.
  7. Start the engine and inspect for oil leaks.
  8. Repair any leaks as necessary.

  1. Drain and recycle the engine coolant.
  2. Disconnect the radiator inlet hose.
  3. Disconnect the throttle and accelerator cables.

92 toyota camry running like on only 3 spark plugs instead of 4, oil getting on spark plugs on the passenger side seeing like black shut on the inside of hood on passenger side

Stop the oil leak. There are gaskets and seals for wherever it's leaking. Valve cover gaskets or seals on the cover if the plugs are recessed. Is the black stuff oil that gets splattered up there?
Spark plugs can keep firing even with oil around the base, but the cleaner the better. A clean engine runs a whole lot better and cooler than one caked in oil. Just don't try to pressure wash it or you'll have worse problems.
It would help you if you could isolate a non firing cylinder, find the one that's missing, I mean. There is a way to find a miss on a running engine by isolating a cylinder that doesn't drop idle speed when the plug wire to that cylinder is removed. But please have someone do it that has done it before. They will know what spark shock means, and how to avoid or mitigate it, or anticipate it-lol. Thatsa lotta voltage!
If you pull the spark plugs out, may help you find the bad cylinder: one will look quite different, may be all black and soot covered on the bottom that is inside the cylinder. Good firing spark plugs will have a tan or brown appearance down at the bottom, with very little deposits on them. (and if black and oily looking and wet, you have likely worn piston rings letting oil burn in there.) So if you could find the miss, it will help you a lot. Maybe you need a tune-up, after looking at your plugs-are they worn down real bad?
Lots of causes for a miss: ignition (plugs, wires, rotor, distributor cap, coil even), gas related (if multiport injection, possibly an injector problem) , and also an internal mechanical problem affecting that cylinder (like a bad sealing valve, a head gasket leak: do a compression test to check for that).
I hope I have helped you in some small way. Good luck.

Do you have replace spark plug tubes when replacing gromets and valve cover gasket on nissan alti mma 05 there was oil in the spark plugs........

IF the tubes are not deformed it should not be necessary. Most problems come from not replacing the grommets and seals every time the plugs are removed.

How to change spark plug gaskets on a 1999 ford escort sport

The spark plugs do no thave gaskets they are a tapered fit into the cylinder head. Do you mean the seals (2.0 DOHC) that keep oil out of the plug wells, if so you must remplace the valve cover gasket, a very simple job on this engine.

Oil on the spark plugs/failing cylinder?

The important question is - oil on the top half of the spark plug, or oil on the bottom (fire) end of the spark plug?
Oil on the top end of the plug means that your valve cover gasket is leaking. This is a common problem. BMW valve cover gaskets get hard and shrink and have to be replaced about every 10 years. It is an easy do-it-yourself repair, but it can take a while to dig the old hardened gasket out of the valve cover without scratching it. Just be patient.
If the bottom (fire) end of the plug is wet, either the plug is not firing due to a failed coil or some other electrical problem, or you have bigger problems in that cylinder. A compression test is in order.

My light says ignition coil b. also the primary and secondary.......what is the primary/sec / AT FIRST IT SAYED #6 misfire. also it still has a slight miss at idle and crussin in overdrive . Can you please...

It sounds like you need a coil for # 6 cylinder .LS's have a issue with the valve cover seals leaking oil into the spark plug holes and causing a misfire if this is the case you have to replace all the gaskets for the valve covers clean out the oil and might as well do sparkplugs then too. Its more of a dealer repair then. If no oil in that cylinder try replacing coil and spark plug.

Cause of oil in sparkplug tube?

1.your valve cover's spark plug chamber seal is leaking. Which requires removing the valve covers and replacing the gaskets and seals. 2. Excessive oil spills on to the valve cover and ignition coils when adding oil.

**This excess oil on the plug boots can cause the coils to short and eventually fail.

There is engine oil in the spark plugs 3 of them,

If the oil is not in the cylinder,and is just around the spark plug,then get a new valve cover gasket with grommets,and spark plug seals,and replace it,if it has oil in the cylinders,it should be smoking,when running,and using oil.

Where is the pcv valve located on a 2003 ford ranger

  • The PCV valve can be located in several places. The most common location is in a rubber grommet in the valve cover. It can be installed in the middle of the hose connections, as well as installed directly in the intake manifold.
  • Once the PCV valve is located, make sure all the PCV system hoses are properly connected and that they have no breaks or cracks.
  • Remove the air cleaner and inspect the air and crankcase filters. Crankcase blowby can clog these with oil. Clean or replace such filters.
  • Oil in the air cleaner assembly indicates that the PCV valve or hoses are plugged.
  • Make sure you check these and replace the valve and clean the hoses and air cleaner assembly.
  • When the PCV valve and hose are in satisfactory condition and there is oil in the air cleaner assembly, perform a cylinder compression test to check for worn cylinders and piston rings.
