Might I suggest to never use paper towels however, I DO swear by them for everything else. I did this exact thing before I even found your video and a piece came off in my cylinder. WAAAAAAY down at the bottom. I thought about using a screwdriver to dig it up but thought about how wrong that would have been. I ordered 12" long skinny medical tweezers to get the paper towel out before I finished my repair. I had to wait 8 days for them to come. I will use blue shop towels for the rest of the oil. They don't dissipate as easily as the paper towels. I didn;t know I could use brake cleaner inside of them tho'. Thanks for that.
I had a cylinder 2 misfire and this video made me go and look at my plugs, and I saw they had a bunch of oil or gas in them...... so I take out the cylinder 2 plug and BAM I saw the problem!!! The prong on the end of the plug had broken off!!! Your video pointed me in that direction and because of that THANK YOU!!!
Awesone, glad it helped!
Very helpful! Thank you
👌🏼
Excellent - might just repair my misfire without having to replace all the gaskets quite yet!
No, you already had a misfire that's critical, so you have to replace all your plugs and head gasket and tube gaskets as well otherwise you will damage your engine.
@@tdf123emcee2 I hope you meant, replace the spark plugs and sparkplug tube seals, why the hell would you need to replace a head gasket just because of oil on the sparkplugs that's leaking from the valve cover...
@@tdf123emcee2 Also a misfire is not critical... Neither is driving with a fouled sparkplug, it's just not the best driving experience but it's not gonna ruin an engine by firing less cylinders, but yea, he should definitely replace the valve cover gasket and tube seals otherwise he'll just mess up the next sparkplugs as well without fixing the leak that caused them to get burnt out
@@tdf123emcee2 you don’t need a head gasket it’s the spark plugs o rings seals why tf would the head gasket cause oil to get on the plugs, head gaskets are on the bottom of the head not the top
@@tdf123emcee2care to answer any of the above questions? I'm keen to learn more from the words of this genius.
I thought for a moment he did had the spark out. I just noticed bit of oil in two of mine. I realized he used the pen or marker to create the exact opening of the plug. So in other words the plug must be in to avoid that oil to get in the cylinder. I replaced my plugs and dnt think any oil got in but will go next weekend and clean it out with he’s method thanks
Hello, does anyone know if it’s possible to get p0354 if there’s oil in the spark plug well? Thank you
How come before I changed my plugs there was oil in the well but with the new plugs it is dry days later?
I wasn't able to clear out much oil in the 2 cylinders that had it, and I had the densest cloud of smoke upon starting it up after the tune-up. It slowly floated away like a cloud.
Can i use contact cleaner insted of break cleaner?
i actually greased the spark plug tread and installed it and i noticed that it was treading more deep,and i found out by many guys in youtube that im not suppose to grease plugs tread,its running fine but is it too late to remove plugs and remove all them grease in it..but how do i get the grease from plugs well without the plugs in it.thank you
i have found oil covering the threads of only one of my spark plugs (bank 1 cylinder 1). Is this likely my valve cover? Externally everything looks dry but I am loosing oil like every few months.
I would suggest using a spray bottle nozzle and sticking the straw end into the well to pump spray the oil out. Then pouring lacquer thinner or brake clean down thw hole to breakdown the remaining oil and spray out. The remaining will evaporate
Good idea. I'm going to try that
Thank you
Being mechanically inept, I dismissed my better judgment and stuck a small piece of cloth taped to a straw down the hole after I’d removed the spark plug. Of course the cloth slipped off and I haven’t been able to get it out with a small hook wire. I can’t even see it. Any advice or do you think I’m stuck towing the car to a mechanic for a scope?
Try piece of hose snd vacuum like in this video:

It’s been a year now so I know that you’ve fixed this issue by now, I wanted to note I did the same thing. Then I remembered how I do timing. So I left the spark plug and the coil pack out and I went and bumped the key. Shot right out.
I've had a literal pool of oil in one of the six wells in my lexus is200 gen1, I've noticed it while attempting to change the spark plugs. There was so much oil the whole ignition coil was swimming in it - from what I remember I tried to get most of this out of there but I let a lot of this stuff get into the cylinder as well after I removed the spark plug, just thinking it's going to be burned up anyways. Don't know how risky it was, the car works just fine since - I replaced valve cover gasket and valve wells (?) gaskets, to hopefully remove the issue for the future.
I know it's been 7 months since your comment, so I don't expect you to answer, but if you have a spare minute I'd love to hear how the engine is going for you after these last few months. I have a similar problem and could learn a lot from you. Thanks heaps. 👍
@@misssummersalt So, after I have changed the cover gasket and coils gaskets, I'm more than happy to say, that nothing terrible happened since then! The engine runs just fine
A couple teaspoons of oil won't hurt anything, but try to get as much out as you can prior to plug removal.
I made the mistake of pouring oil into one of the wells thinking that it was the oil reservoir with the spark plug out. I stopped after 2 or so seconds of pouring it. It wouldn't crank with the spark plug back in there, and then I tried to crank it with the spark plug out and it spewed a bit of the oil out of the well. What should I do next? Should I wait for the oil to seep back into the block? Do you think I did any damage to the block?
This is actually an old trick if you get oil in those plug holes from the bad gasket , you can remove the plugs 1 by 1 and job the motor each time and it will shoot the excess oil out then just replace plug and move on with life. Solved a misfire by tmdoing this on a 95 civic.
@@josephfrye1493 that's exactly what I resorted to doing, but you could only imagine the fright I was in as I'm not mechanically inclined xD
even batman couldnt get that info out of me ngl
@Gseric47 I wasn't very Mechanically inclined either I had to change a valve cover gasket a few years ago and my dad told me about it I was like heck it better then a misfiring 4 cylinder
wow! You are you own worst enemy
Great video thanks!
Glad you liked it!
So yeah I like the video but you should have explained what's so important about the oil on spark plug and in coil pack compartment & what would happen if you don't remove it B4 putting new plugs..
What would happen?
Youre doin this with the spark plug still in place right?
Absolutely. Don’t even think about removing the plugs without removing the oil from the spark plug tubes first. Remember, the whole point of this is to keep oil OUT of the ignition chamber, which may cause misfires.
If the stray tissues or anything gets into the cylinder hole then there goes u have to open up your engine.
I got a question I had oil in my spark plugs but I’m not sure if the piston or head caskets r broken but only little smoke is coming out of the exhaust should I be fine?
Pistons is fine you may need to replace your spark plugs seal and possibly replace the gasket but the spark plug seals might be finished
@@mustagkeemharris5841 it was exactly that and went to a shop to get fixed
@@Jackyyyyboii glad you sorted out
@@mustagkeemharris5841 I got one more question tho, my car would still rough idle if I go really fast and I was wondering if u know what cuz that
Have you changed your spark plugs and cleaned injectors this could be of the preview ptoblem of the spark plug seal so check your spark plugs they might need to be cleaned or replaced
I took out all the spark plugs 😢 all the oil went down to the chamber, what do I do now?
More than likely it'll just be burned off in the cylinder. What happened with it? Was it ok?
Yeah it smokes for a bit then went away
It’s better to use one of those spray long bottle straws to take the oil out,like the ones to clean your windshield it’s pretty long to stick it into the hole,I hope you’d s understand what I’m saying
That’s great idea! That’s what I’m using next time I need it!
Did u take the spark plug out to clean the chamber with brake cleaner? Thanks
No, kept it in. You don’t want oil to sip into the cylinder.
If it seeps into the cylinder is there a way to clean it out? Happened to me and now I’m getting oil on my plugs still after changing gaskets. I’m a rookie
I just changed the valve cover gasket and spark plugs, did not clean them unfortunately. The car runs fine but there is a plastic burning smell. Any ideas?
Can you trace it to anything specific?
I have the burning plastic smell as well. Oil in spark plug tubes. I think it's the ignition coil melting to the tube.
@@DIYtime not really, the car runs fine but it's still there.
Tampon...would work as well.
Just ask a female friend if she could spare one....LOL.
😁👍🏼
I have a 4 cylinder engine it fell and all the oil went to the air intake manifold how do you get the oil out of manifold
bruh
at that point man it’s best to take it off and clean it, let it dry, put it back in
What if that paper towel get stuck??
You can use a Stanley hook set to get it out.
I would say that one should maybe add a tight band around the towel and pen and use a handy pair of pliers for extended and firmer grip.
Do you remove the spark plug before cleaning the well?
I dont. Otherwise oil may go into the cylinder.
@@DIYtime I made the mistake of removing the spark plugs with oil in the well. The oil has now dripped down into the cylinder. How do I get the oil out? The car no longer starts because the plugs get immediately coated with oil. I am screwed. Now I have no car. Any suggestions?
If you wait a bit, oil may actually seep through piston rings back into the engine block. You can rent a bore scope at Auto-parts to see if its all gone, just to be safe. I’m just hoping you didnt cause any damage when you started engine with oil in cylinders.
@@DIYtime the car won't start now and I did try to start it quite a few times. What kind of damage could I have done?
Is it cranking at all?
i get water in the well
Or just use a compresser if you have it and blow out the oil then brake cleaner the the air again
Ok but sticking paper towel inside that spark plug hole to get the oil out is not good because can leave somepart of the paper inside.a rag will be better
Rag will not reach all the way to the bottom. I used thick good grade paper towel, and it worked great for me.
Ive been using Straw.....
If the engine runs, gas and air gets poured into the cylinder 2000 time a minute. You dont think that would clean all the oil out??? If oil was inside the cylinder, your plug will probably be fouled and need cleaned or replaced.
sorry ford leaks rainwater down firewall into plug holes, requires new plug boots as old shrink up.
Hmmm ofc it's a 2AZ with this problem.
I accidentally overfilled my oil (checked it on a non flat surface). Went to change spark plugs and 2 were drenched in oil. I actually used paper towels to absorb the oil. Didn't get it all, but most of it. So far no issues with the truck. We'll see.
How's it going ?
hows the truck been? i just overfilled my 350 sbc with oil and hydrolocked it, removed plugs, sprayed it with wd40, cycled it a few times, sprayed them all again with wd40 and let it sit with the spark plugs overnight, about to put them back in and see now
Use a straw
Do not do this. Use an actual cloth towel wrapped around a screwdriver.
Cloth will not get around the spark plug to reach the deepest part of the well.
@@DIYtime You're supposed to take the spark plug out
And let the oil get into the cylinder....!?
@@klutch... Are you saying this because you think the paper towel will tear and get lost forever in the spark plug cylinder hole? I just did this technique using paper towel and a flathead screwdriver and non of the paper towel tore away. Even if it did tear away you could easily retrieve the paper towel with some long tweezers or stiff wire. Worst case you would just continue soaking the oil up and then loosen the spark plug out to retrieve whatever paper towel you couldn’t get out.
But the video poster is correct, paper towel is really the only way to get maximum absorption and coverage area to get every last drop of oil out.
Please for the love and Pete, don’t ever do this… just wow
Already did. Worked great!
Why?
terrible video
