I am pretty sure the plug is 12X125 but you should take one out to make sure, there are a few spark plug kits available i use HELI-COIL for repairing threads my choice. and the coils come in 3 lengths.

I have a hushy power washer and the spark plug popped out while I was using it. is it any good now or is the motor blown?

Hi Jean Cunningham...
Go to your local auto parts dealer and ask them for a "Heilicoil Set" to fit your spark plug. It will have a tool in it to rethread the stripped head threads and a special insert to fit your plug will go into the rethreaded head....pretty simple job.
Good luck,

2004 Toyota Tundra spark plug

The causes for spark plugs leaving the cylinder head are as follows:
1. The threads in the cylinder head were compromised, as in cross-threading.
2. The spark plug, when replaced, was not tightened down properly (like only 2-3 threads in)
3. A combination of the above.

Whe the plugs are fully seated in the cyl heads, and are at the proper torque, it would be extremely RARE for the plug to be jettisoned by the compression of the pistons. You only have roughly 175-185 PSI compression, this will NOT defeat the retention of the threads. Look at the hole in the head...How may threads are damaged? If it is just the end of the hole, the plugs was not in "all of the way". If ALL of the threads are bad, the plug was inserted improperly, and damaged the threads in the head. Rethreading (a "heli-coil") will correct you condition, if properly done.
Hope this helps.

Spark plug blowout

No, can't see how?
Make sure you lubricate spark plug threads with anti seize paste and don't over tighten.. usually hand tighten till plug bottoms + 1 flat of hex.
