I've heard of a new thread called Helicoil. I used them in the past, guess they work ok.
Hope this helps.

I have a 2000 Volkswagen Beetle 2.0 5 speed the number 2 cylinder keeps blowing the spark plug out of the hole what would cause that and how to fix it?

The spark plug should not come out if it is the proper application spark plug with the correct torque. Sounds as if the plug hole may have damaged/stripped threads which can lead to a costly repair. There is an alternative repair for this without removing the cylinder head. A Heli-coil can be installed into the damaged plug hole. If installed correctly, this repair can last the life of the vehicle at a fraction of the cost

I can't get the spark plug tight on a 2000 Lincoln towncar

If the spark plug is turning and the threads are properly seated in the threaded hole, then the threads are stripped out. The only way the threads can become damaged is using a wrench to start the threading process. Spark plugs should always be started by hand, even if a socket and extension is used, it should be turned by hand, not with a ratchet. Unless the spark plug was cross threaded before, verify the threads are engaging and turning by hand only. Otherwise the hole will need to be re-threaded and will require head removal to do it correctly and keep metal from entering the combustion chamber during the process, thus causing internal engine damage.

1997 ford expedition spark plug blow, its all strip. its an aluim head. is there a quick fix or do i have to replace the whole freaking heads?

The Spark Plug hole can be repaired. The professional way is to remove the cylinder head, and use a repair such as a Helicoil.

The spark plug hole is tapped out to a larger thread size, with a special Helicoil tap. Loctite or some other form of thread locker is applied, and the Helicoil is inserted.

Helicoil's are made of Stainless Steel, and are much better than the original material used in the cylinder head. (Be it cast iron or aluminum)
Drag racers use Helicoil's in their engines.

Tapping out the spark plug hole for a Helicoil, or using a special thread chaser, is NOT a good idea, while the cylinder head is still installed on the engine.
The tap creates chips of metal which fall down into the cylinder.
Using a vacuum to try to alleviate the chips, falls short of a good repair job.

Spark Plug: Service and Repair
J 43094 Spark Plug Boot Puller
1. Turn OFF the ignition switch.
2. Remove the ignition coil assembly.
3. Use the J 43094 in order to remove the spark plug boots from the spark plugs.
NOTE: Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug
threads to seize causing damage to cylinder head threads.
NOTE: Clean the spark plug recess area before removing the spark plug. Failure to do so could result in engine damage because of dirt or
foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the
proper seating of the new plug. Use a thread chaser to clean the threads of any contamination.
4. Remove the spark plugs from the engine.
NOTE: Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the
vehicle. Installing spark plugs of another type can severely damage the engine.
NOTE: Check the gap of all new and reconditioned spark plugs before installation. The pre-set gaps may have changed during handling. Use a round
feeler gage to ensure an accurate check. Installing the spark plugs with the wrong gap can cause poor engine performance and may even damage the
1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement to the gap specifications. Refer to Spark Plug Usage.
Correct as necessary.
NOTE: Be sure that the spark plug threads smoothly into the cylinder head and the spark plug is fully seated. Use a thread chaser, if necessary,
to clean threads in the cylinder head. Cross-threading or failing to fully seat the spark plug can cause overheating of the plug, exhaust blow-by, or
thread damage.
NOTE: Refer to Fastener Notice in Service Precautions.
2. Install the spark plugs to the engine.
Tighten the spark plug to 20 N.m (15 lb ft).
3. Install the spark plug boots to the ignition coil assembly.

4. Install the ignition coil assembly.

The plug is possibly stripped in the hole and needs mechanical attention immediately. Have a mechanic put a helicoil in the hole where the threads are damaged. Whoever changed the spark plugs last was a **** and needs to never touch another car in his/her life
