Should You Lubricate Spark Plug Threads?

Can I use grease instead of anti seize?

You can use grease quite effectively as an anti-seize compound.

It’s not as good in high temperature applications, but there aren’t any of those on a bike.

However, NEVER use anti-seize compound as a lubricant.

grease reduces the friction between two surfaces and allows them to pass over each other with less effort..

Can you put oil in spark plug hole?

Remove all of the spark plugs, and using a squirt can, shoot about a tablespoon of engine oil into each spark plug hole. Once this is completed, gently rotate the engine BY HAND a few times to help re-coat the cylinder walls with oil and to make sure it actually turns over and doesn’t have any other issues.

Is it bad to have oil in spark plug well?

Oil in a spark plug well is a very serious problem that should be repaired as soon as possible. It can do extensive damage to the engine, such as broken or warped pistons and valves. Eventually, if not repaired, the head gasket can result in the fatal destruction of the engine.

Can I use white lithium grease on spark plugs?

The grease that should be applied is white lithium grease. … Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.

Will bad spark plugs throw a code?

Bad spark plugs can cause your engine to misfire. The engine’s computer uses sensors to detect these misfires and will create a code that turns on the check engine light. A flashing check engine light indicates the misfire is severe enough to cause damage to your catalytic converter.

What happens if you don’t tighten your spark plugs enough?

An under-torqued spark plug will not make full contact with the cylinder head. … An over-torqued spark plug can cause stress to the metal shell, leading to thread damage or breakage. Over tightening can also compromise a plug’s internal gas seal or even cause a hairline fracture in the insulator.

How tight should you make spark plugs?

The tightening angle for both new and reused spark plugs is 1/16th of a turn. When it is difficult to use a torque wrench, or when you don’t have a torque wrench, tighten the spark plug to the tightening angle shown in the illustration in accordance with the thread diameter of the spark plug.

Does spark plug gap have to be exact?

The gap between the center and side electrodes of a spark plug must be an exact distance; otherwise, your plugs don’t fire efficiently. Adjusting the distance between the two electrodes is called gapping your spark plugs. You need a feeler gauge to gap your spark plugs properly.

How do you lubricate spark plug threads?

Apply LOCTITE 767 (ANTISEIZE LUBRICANT) (P/N 293 800 070) over the spark plug threads to prevent possible seizure.

Why is there oil on my spark plug threads?

Bad spark plug tube seals are the most common cause of oil on your spark plug. … This is caused by a bad spark plug tube seal. Replace the tube seal requires removing the valve cover and changing the valve cover gasket as well as the spark plug tube seals.

Can a fouled spark plug be cleaned?

How To Clean Fouled Spark Plugs. To safely clean a spark plug, you should use a wire brush or spray-on plug cleaner specifically designed for this ignition part. Note: NEVER clean a spark plug with a shot blaster or abrasives.

Do you grease spark plug threads?

NGK does not recommend the application of lubricant such as copper grease to spark plug threads as the result is a reduction of frictional forces at the thread faces. … It’s very important not to over or under tighten spark plugs during installation. Over tightening can lead to distortion of the spark plug and breakage.

Can Vaseline be used as dielectric grease?

Vaseline can work as a substitute for dielectric grease, the big differences are that it can degrade rubber and plastics over time, and it’s combustible – but I’ve used it in the past on car bulbs, wiring and battery terminals and it hasn’t been a problem yet.

Will anti seize cause bolts to loosen?

Using anti-seize without reducing the required torque value can strip the threads or stretch the bolt in extreme situations.

Is it OK to use never seize on lug nuts?

But experts tell us not to use any lubricant, including anti-seize compound, on wheel studs or nuts. The tech folks at Tire Rack state: “Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. It is important NOT to lubricate hardware threads or seats.

Is it OK to put anti seize on spark plugs?

Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Thread breakage can sometimes involve removing the cylinder head for repair. … Do not use anti-seize or lubricant on NGK spark plugs.

Can oil on spark plugs cause misfire?

In an ignition misfire, the spark plug for a given cylinder fails to ignite the fuel when it enters the combustion chamber. … As far as oil goes, this usually occurs because a layer of oil has coated the spark plug. As previously noted, the culprit is often a worn seal such as a gasket, grommet or O-ring.

Where do you grease spark plugs?

To use dielectric grease during an automotive tune-up on a gasoline or diesel engine, apply a bit of the grease to the end of the rubber boot on a spark plug wire and spread it around so it is just covering the inside of the lip.
