Wet plugs can be from 2 things -- excess fuel ==faulty injectors==excessive fuel pressure in manifold==faulty ECM and 2 excesive oil by passing the rings. have the fault codes read to find faults in the control systems sensors and have a compression test done to determine engine condition. That will also show if the wet plugs is from a cooling leakage problem

I have a Nissan hardbody 2.4i petrol the plugs are getting wet and it starts to misfire what could be the cause

It is a chicken and egg question - which came first, the wet plugs or the misfire?

Are the plugs wet with fuel or is it oil?
Are all the plugs equally wet?

If the ignition system is in good order and the correct spark plugs, correctly gapped and in good condition are fitted, it would be expected if the engine was receiving (moderately) too much fuel, it would keep running until the plugs were completely sooted, black and shorting out and unable to spark properly but at that moment the plugs would still be quite dry.
Persisting after this will of course cause wet plugs if the engine is still relatively cool but the sooty evidence of what has happened will still be there.

If the plugs are relatively clean but wet it is unlikely to be fuel as such large quantities that is would take to wet the plugs without any sooting it would be doubtful if the engine ran at all.

I hope I have provided you with food for thought. If you need to post again please provide accurate and detailed descriptions of the symptoms and what you have already checked.

Whats the proplem ifthe spark plug is wet with petrol

If the plug is wet with fuel, it is an indication that the plug is not firing properly. Possible causes? Distributor cap, rotor, points/inductive pickup, spark plug wire or the spark plug itself. If you or a friend, relative, etc. has or has access to an inductive pickup timing light, connect the light to a power source and the inductive pickup to the plug wire of the "wet" spark plug. Start the engine and observe if the flash from the timing light is relatively constant in its frequency or is it erratic and sporadic. If the latter is true, check the distributor cap, rotor, distributor points/inductive pickup and plug wire. If the former is true, remove the spark plug and check the compression against other cylinders. If compression is good, replace the spark plug with a new one. If compression is lower than others, the air/fuel mixture in that cylinder is not being compressed engough for combustion, leaving the spark plug "wet". To learn the cause, put a teaspoon of motor oil in the spark plug hole, and recheck compression. If it doesn't increase, you probably have a valve or head gasket problem. If it does rise, you probably have a piston ring problem . Good luck

Wet spark plugs

wet plugs indicate excessive fuel in that piston that is not being ignited. Possible plug failure or HT lead failure or distributor cap crack for the piston or coil pack for that piston

I'm getting codes, p0301 and p0316. I replaced the spark plugs and cylinder 1 spark plug was wet when i removed it. What could it be?

Code 301 is a cylinder miss on cylinder one, and 316 is a miss detected during startup which is probably caused by code 301.
If the plug is firing, you could have an injector problem on that cylinder.

I had 92 honda civiv hatchback, the sparkplugs get wet with engine oil from vave cover, does sparkplugs has its own individual seals?

The spark plugs, if getting wet from the engine oil dripping off of the valve cover gasket, is not good.
The boots of the spark plug wires will prevent the contacts from getting oily, but not for long. I would have the valve cover gasket replaced to prevent this from happening. It's not good to get the spark plugs and wires wet with engine oil.

a host of reasons,
  • check if you have a spark buy removing ht lead from spark plug and holding near metal pat of engine while cranking, use insulated tool to hold lead, if spark thats ok
  • remove spark plug after lang cranking and smell if gas is present or plug is wet, if wet you are geting fuel
  • then ask again once you know what is not happening
  • has it electronic ignition
  • has it fuel injection or carbs

Spark plugs for my 2001 nissan altima is always wet with oils and there is no spark, what's the problem?

The spark plugs are probably wet with petrol, rather than oil.

This happens because they are not firing, and the petrol is not being burnt.

This is mostly likely caused by a faulty ignition system.

Does the car start at all? Does it run roughly?

1988 nissan pulsar wont crank

The black color of the spark plugs indicate that the engine was running rich (too much fuel). The fact that they were wet tells me that there may not have been ignition. The carb being wet may be just from flooding when you tried to start the engine.
First off you need to determine if you are getting spark. You can do this by connecting one of the plugs to a wire and grounding it to the block. Have someone crank the engine and watch the plug for spark. Blue is good yellow is week. Use care holding the plug as it can give off a nasty kick. If you don't have spark than its time to check the wires, distributor cap, rotor and so on.

2001 caviler and it will turn over and want start

it could be a lot of things.... did the car just die? was the weather wet? does it turn over fast..? is there any spark getting to the plugs? plug a spark tester into the plug wire and set it to a low gap .030" see if the arc jumps the gap. if it does pull a spark plug out and look at it. it should be golden brown with a fairly square electrode. the ground should be over top of the electrode not eroded away . can you smell fuel when u try to start the car? when u crank the car over and it doesnt start are the spark plugs wet?
