Broken spark plug extraction

[@theindianwaves5981]

🤩🤩... That good feeling when first we will be able to rotate that broken piece after too much effort .... is priceless.

[@DangarMarine]

So true!

[@kingstonzincfence]

Pricel indeed!

[@Kurtdog63]

I made a mistake and bought a pickup truck many years ago that had a lot of rust on it. After owning for a while, I took it to my mechanic to replace spark plugs. When he took a closer look at the truck, he stated he thought the truck had been submerged in salt water. He stated that he had never seen so much rust on a truck inside and out. Some of the frame was almost rusted in two! Anyway, the first spark plug broke off just as you described. He could not get it out with easy out, so he decided to heat it with a torch. He stated if you do this, you have to blow compressed air into the cylinder and remove all fuel fumes before putting a torch to it or 4th of July might start early. The heat worked and an easy out got it out. All the other old rusted plugs were still firing so he quit while he was ahead. Thanks for sharing tip.

[@douglasjohnson8820]

I always put Never Seize on all my plugs when installing. Never had one frozen up or break when taking out. Both Inboard and outboards.

[@fulwell1]

Watched this a second time just to comment - excellent video (as always), and a great tip that can be applied to anything automotive that has spark ignition. Also nice to see a mention for Snap On - I love their tools!

[@DangarMarine]

Thanks mate. SnapOn do make great tools, even if they are a little expensive.

[@lyleneumann2245]

That tool works great. Will look for the snap on truck in my area. Thanks for the video.

[@DangarMarine]

It certainly did the trick in this case. I'm sure there are plenty of other tools that will do the trick. I'm hoping this tip didn't come across too much like an informercial - it was just a co-incidence that he turned up and I paid full retail for it. I'm sure there are plenty of other gizmos you could try if you had this problems.

[@crispernator]

gday mate it amazes me how people let their engines get in that state it doesnt happen overnight good you got them out

[@DangarMarine]

Yeah, I don't think anyone had looked under the cowling for quite some time!

[@thilltony3362]

Oh, I like that tool so much better than the little short ones I use. Thanks for the quick tip!

[@DangarMarine]

I was really happy with them. Simple but effective!

[@wayne1959]

I reckon that snapon guy has covert caameras in our workshops..he always turns up just when we need him..lol well I am a toolaholic after all..lol handy vid Stew, I am loving the old posts while awaiting your latest.

[@DangarMarine]

I think you might be right!

[@melvinolthof6881]

never seen a sparkplug broken of like that thats one lovely tool

[@DangarMarine]

Yeah, that plug was in pretty bad shape and that tool was a real life saver.

[@matthewmoses4222]

It just goes to show how easily something neglected for a few weeks turns into months then years.

[@DangarMarine]

Too right Matthew. This would have been much easier if it had been dealt with a bit earlier.

[@paulsheppard3158]

Nice practical work😅 well done Stu

[@DangarMarine]

Thanks Paul, I was worried about this one.

[@MattsShop]

Man! I thought my fresh water plugs were getting nasty when they had a little bit of white corrosion on them. Those are crazy nasty.

[@DangarMarine]

Yeah, they were probably a week or two past their due date. ;)

[@MattsShop]

Haha Yea I'd say so.

[@CaptivatedGaming]

Dangar Marine will this work even if there is porcelain in there? I have an 06 mustang gt and 2 plugs broke since the owner didn't change them when they needed to

[@divinesunday7951]

This just helped me out, thank you

[@DangarMarine]

Glad to hear it!

[@shawnnelson2920]

+Dangar Marine Thanks for all your videos ! I'm current having issues w my mercury outboard tilt release valve nylon screw....the head of the screw snapped in half when trying to release presume so I could lower my outboard...I assume it has never been turned since 94 or so....I was going to try an easy out with some heat to back out the screw a bit. Any thoughts or tips?

[@11bayrat]

Hi. Grate tip. Did I miss the 2nd video On the putting back together 150 motor. I think you where going to have the heads machined ?

[@DangarMarine]

Thanks Bruce. No, the Evinrude is still with the machinist waiting for pistons to arrive from the US. Must be coming by sailing ship...

[@Max-kw4px]

What would you recommend doing if the spark plug well is corroded? Just pulled some old rusted plugs from a new to me engine and the mating surface on the engine block is corroded and full of rust -> I'd imagine that trying to install a new plug and sealing washer on top of that is a recipe for leakage and very poor engine compression and performance! Worried about cleaning it with a wire brush seeing as metal bristles could easily end up in the combustion chamber, which would be bad news!

[@beastly5569]

Was there any reason you didn't use a much larger adjustable wrench to get more torque? It seems like that would have made it easier.

[@DangarMarine]

Only because I just grabbed the closest thing to hand. If it hadn't come free I would have put a bit of heat on and found something with a longer handle.

[@dwamc]

Hi DM I'm sure what you really meant to say was - it is always a good idea not to use a pull bar or similar so that you get a feel for the tool doing it's job so that damage is not done to the threads etc. "Well saved" Lol.

[@DangarMarine]

Ah, yes, that's it! Always start with a breaker bar then go to something smaller if it snaps. ;)

[@stanpatterson5033]

Nice technique with that tool. Had a friend's Buick Century lose a spark plug out on the freeway some months back. Did some damage as the porcelain part came unbonded from the steel at the bottom. Never seen a spark plug fail like that before, it scared the crap out of us when it happened, was quite violent under the hood. It was a transverse-mount V6, it was the center plug facing the firewall. Destroyed the plug boot and plug wire, bounced off the firewall leaving a dent, fell down clanking all the way before hitting the pavement and then the bottom of the vehicle a few times before clearing out the back. We hit the shoulder to have a peek at what the heck had just occurred. The Buick drove home (noisily) on 5 cylinders, sucking and blowing through the open hole. No trouble getting the collar of the spark plug out of the engine block, and never ever did see the top of the plug, but we were just really surprised that the bond would let go.

[@DangarMarine]

It is amazing that it can happen, particularly while driving along. Must have been quite a shock when it happened!

[@curth9204]

What did you use to get remaining plug out then? Just happened on my 3800 engine no 1 plug 2004 Grand Prix

[@wryanddry2266]

Now how are you going to get the porcelain debris out of the cylinder?

you made that look too easy Stu,isn't it great when these things work,regards,Kevin.

[@DangarMarine]

I know, that's why I filmed it. ;) When the first one came out I thought, holy crap, these things never normally work for me!

[@kevinsouth1216]

did you feel like slapping the boat owner ? lol

[@timcovey6626]

Really enjoy your videos I have a 150 Evinrude I would like to take them Kingpin where the ball motor pivots to the boat and redo the bushings have you ever done one of these

[@DangarMarine]

This is quite an old video on doing that job on a smaller motor. I should do a new version on a larger motor one day, but the process is pretty much the same kzbin.info/www/bejne/mnvTqGx_f557Z7c

[@johansjons3510]

Thanks! This looks exactly like what I need. What's that tool called though? I've been on this for days, trying everything from heating the broken piece to drilling holes in it so that I could get screws in and then use them for better leverage but nothing has worked so far

[@DangarMarine]

Link in the description to the tool.

[@johansjons3510]

@@DangarMarine thanks! I ended up modifying a screwdriver and use that, and it worked (but I had to use pipe pliers to and reaaaally bend it). So saved the day! My Mercury 9.9 still won't start, though...

[@gregohare6412]

I guess if you drop some of the spark plug's annode or insulation in the cylinder, you would have to remove the head before the debris does any damage? Is there a tried and true method for removing a bolt that has broken off flush with the mating surface. I guess drill a hole (progressively larger) and then use an easy out. Do you spray anything on the threads to loosen the threads? Great videos. Thanks for posting!

[@DangarMarine]

If something goes into the cylinder you do need to be careful as you say. If it is only one or two large pieces I would probably try to fish them out through the spark plug hole, but with a two stroke it isn't much work to get the head off so that is probably a better approach. Easy outs are a good way to go, or welding a nut back onto the bolt, particularly if there is a little bit of thread left. I'm going to do a complete video on corroded / snapped bolts soon.

[@gregohare6412]

Great videos. Look forward to seeing your broken bolt video. Thanks for sharing your knowledge and experience. You are a natural teacher.

[@yoyohooyo]

I never had that good of luck getting these things out and on aluminum heads they usually brought the thread with them when they did back out.

[@DangarMarine]

Yes, it is very common to put a bit of aluminium antiseize on plugs when putting them in an outboard.

[@southo69]

Fantastic... The Snap-on man has a way of knowing when to turn up for a easy sale - ha ha ha

[@Chris-ei7iz]

I've always used to oversize flat head screwdriver you tapping in the same way you just did that tool the lock pair of ice grips onto the screwdriver handle it works the same way it's probably cheaper than that too

No, it was a different outboard again. Belongs to a young bloke on the island, the CVs are still waiting to be done.

[@jerrychf]

Any recommendation about those WD-40 rust release oil? or not to using it?

[@DangarMarine]

I think it's always worth putting a bit of penetrating oil on stuck parts. It won't work miracles but it will help.

[@carlosh.deseixas4850]

i Liked... i don't know this tool. congratulacions... Brasil ponta grossa city

[@DangarMarine]

Neither did I! It was pure co-incidence that the truck turned up just as I came across this problem.

[@jamesdahmer5027]

Hey so lets say you bought a Merc 9.9 for $100 because the owner couldnt get it to run right, and in removing the spark plugs you find that they have completely cross-threaded and destroyed the spark plug sockets... If I'm real careful, I can replace them and have the motor run like a dream. Is it possible to tap in a slightly larger set of plugs? with/without actually buying a tapping tool?

[@DangarMarine]

You might find you can get the plugs back in if you are lucky. Otherwise the best way is to install new threads like this www.ebay.com.au/i/282925788348?chn=ps

[@jamesdahmer5027]

thanks!

[@BradG902]

Hey Stu, love your work. Do you happen to have any videos on cleaning the corrosion off around the spark plugs (looks similar to the thumbnail of this video) - my 8HP has it quite bad - and I'm not sure where to start with removing it, repainting and which products to use. Thanks man

[@DangarMarine]

Hi mate, not specifically but I would wire brush it as best you can with the spark plug in so no debris goes into the cylinder and then look into a rust inhibitor like phosphoric acid.

[@BradG902]

​@@DangarMarine awesome thanks for the reply! The paint is actually flaking, so I guess I'll have to prime + paint - any particular products you recommend there?

[@DangarMarine]

Use an etch primer first and make sure the paint has good heat tolerance.

[@joeantolak4629]

Brilliant

[@modemagic1]

A slang term for that tool in the US is an "easy out". Ironic though because there is rarely anything easy about it!

[@DangarMarine]

Couldn't agree more. So EZ-Out is a registered trademark of a particular brand of extractors, but I've never had much luck with them. The trouble is they are tapered so as they bite down they put pressure on the walls of the thread and actually hold them tighter. I was pleased this worked, but I think it was more to do with the fact that this had rusted apart rather than the thread being corroded like when a bolt snaps.

I'll have to check that part number when I get back to the workshop, I should have put it in the description, I'll do that once I have it. I'm not sure how long the injectors in etecs last before they cause troubles, we only very rarely deal with them as they require quite a bit of specialist equipment to re tune after an injector has been changed.
