Either it is the wrong spark plug or you have stripped threads.

If the treads are stripped, you can buy a kit to fix it or re-tap the hole. Worst case scenario, you need a new head.

Hi and welcome to FixYa!

If the spark plug is not tight it tends to pop out. No need to worry just tighten it for it not to pop out. It may damage the hood if it pops out with the hood closed.

Hope you find this information helpful enough and thank you for using FixYa! Have a good one!

One of the spark plug caps pops up while I'm driving. I can't think of a better way to describe the problem. Of course I didn't know what happened the first time it did this (which was 4 days ago) I pushed...

If this is a cap that seals to the cover or head around the spark plug, it could be that the plug is loose and compression is popping the cap off. Try gently tightening the plug with a spark plug socket. It could also be that the plug wire needs replaced due to the terminal that snaps on the spark plug itself being loose.

The treads for my spark plugs are striped, and I can't find a tool long enough to fix them.

There is a tool specially designed for that job, Spark Plug Tread Restorer, it is sold at most auto parts stores for under $5.
Good Luck!! Don't forget to rate this post!!

Spark plug blew out of motor

The spark plug blew out because it was not installed correctly and was loose. Install a new plug and do it very carefully as there may be carbon in the treads the plug screws into. Screw it in until you feel it getting tight and then turn it back. Keep turning in and out until it fully seats. Always follow the vehicle manufacturer torque recommendations, but as a general rule 14 mm plugs with a gasket style seat should be tightened to 26 to 30 ft.lbs. in cast iron heads, but only 18 to 22 ft.lbs. in aluminum heads. Likewise, 18 mm plugs with gasket style seats should be tightened to 32 to 38 ft.lbs. in cast iron heads but only 28 to 34 ft.lbs. in aluminum heads. For taper seat spark plugs, 14 mm plugs should be tightened to 7 to 15 ft.lbs. in both cast iron and aluminum, while 18 mm taper seat plugs should be tightened to 15 to 20 ft.lbs. in both types of heads.

Right i own an 03 tm 125 and i took it out got to the track and it wernt starting at all. then bought a new spark plug , it stilll wernt kicking. so i bumped it and it onlky jus started, then rode off...

Sounds like you had the engine flooded or the spark plug was fouled. When you changed the spark plug, you apparently forgot to tighten it properly. You may have damaged the threads in the head. I doubt you blew up the engine but you need to have the treads in the head repaired if they are damaged. Any good machine shop can install an insert into the head to repair it.

How do i remove the spark plugs

Remove ignition wires from spark plugs, then use a 5/8 deep wall plug soket and turn to left with ratchet to remove plugs from cylinder head. do it with engine cold, if hot you can rip the treads out of the holes, soft aluminum. Install new with tread of plugs lubed with anti-seize lube (silver stuff). and torque to 20 ft lbs.reinstall ignition wires on plugs. not to mix wire location do it one at a time.

I have a proform treadmill that slips as soon as i step on track i looked at the belt it looks good how do i tighten up the track

There should be adjustment screws on the back left and right sides. The screws will be horizontal with the tread, and probably need an allen wrench to tighten. If the tread runs straight, tighten each side 1/4 turn at a time to keep them even. Check the tread after each adjustment, and stop as soon as the tread quits slipping.

How do i change spark plugs on a ford escort sport

start from the left hand side of the engine as you are facing it, take one out at a time this way you will not mix up the HT leads ok.
Take the lead off number one plug and unscrew the old plug anticlockwise with a socket that fits the sparkplug, once you have done that put the new one in and tighten up clockwise and put the lead back on and push down so you hear a click but do not tighten up to tight or you weill damage the treads on the plug. Just enough so you feel the pressure on the racket. then do the same with all of them.

I hope this help's?

I can't get a spark plug reinstalled in my '95 Mazda B2300 2WD

you can put a little bit of oil on the treads to get it started. Do not cross tread it because it will strip the hole out and you will have to replace everything.

Plugs treadings

Yes there is a Nice, professional fix for your issue. You will need to call an autoparts store, or take the plug to a hardware store and figure out the thread pitch and plug diameter. If you give me the application I can look this information up for you. HEre is the source for the kit, its very easy to do, and if you take your time, the fix can be done without damage to engine. The kit will come with instruction on how to use it, however the KEY thing is to use wheel bearing grease, and constantly clean your tools after a 1/4 turn or so, to keep metal shavings entering the cylinder to a minum. Also what you need to do is change your spark plug changins tactics. When you change a spark plug first off all the engine must be cold. Allow it to cool 6-8 hours before removing spark plugs. Secondly always hand tighten the plugs before using a ratchet. Last but not least- use a torque wrench to torque the plugs to spec. Following these 3 steps you'll never have an issue. I can walk you through step by step once you get the kit. I use them allot at work, and I assure you that they are the highest quality on the market.
