This is the video I was WANTING for ever!! I changed my oil and filter on my 2000 ford expedition 2 weeks ago and I checked today and it was LOW on oil. I screamed!! I add a quart and I see those kinds of marks on the engine too. I need to replace my valve cover gaskets!! Thank you SO MUCH!! You have saved my DAY!!!

@5:10, "and tighten all your bolts". This would be a good spot to add a disclaimer that these MUST be tightened to spec using a torque wrench according to manufacturer's guidelines.

[@josetellez1803]

Somebody's been watching chrisfix! Lol. Good point though

[@legionact]

unless you're actually messing with something inside the engine you should be fine knowing what a decent ugga dugga can do lol

[@mohsiniqbal7924]

I stripped my bolt and it’s stuck inside 😭

[@ricardoperez8879]

Cross pattern when tightening is also recommended so that the gasket is pressed evenly.

[@halloftripplesix]

Lmfao, torque on valve covers are 18-22lbs foot… you can do that by hand

[@jacksonharrison6624]

Ok I love how scientific his tone was when he said “And because Oil is so sticky, dirt will stick to it” 🤣 idk it just got me.

[@mikeletterst9882]

😂😂😂

[@ReyLaFleur]

Also remember some cars require silicone on sharp corners of the mating surface! Great vid :)

[@hugh3rdof5]

Just what I've been hoping to see more of from 1AAuto.... not just the usual helpful how to fix, but a very helpful discussion of knowing just why you might be needing to do this. Thank you. (and also for the useful comments and replies below)

[@1AAuto]

+hugh3rdof5 Thanks for the feedback!

[@melnewdem9929]

Your the man-chanic!! Seriously though I watch dozens of videos and they didn't answer half the questions I had!! I am a subscriber now...

+Melissa Dempsey Thanks for watching and subscribing!

[@zaphodbreeblebrox9542]

Some gaskets have an up-side and a down-side. Look at the gasket that you are removing to be sure which way it goes.

[@Leightmo]

Thank you this was a very simple and understandable video!

[@selfresponder6043]

You are a lifesaver, thanks for sharing.

[@chrisbeard5794]

I'm doing this on my 2017 Ford Fiesta SE tomorrow, do I need to use a sealer? And will Dawn soapy water work instead of a degreaser?

[@aprilsantos8653]

Very informative. Thanks. I understand what the mechanic will have to do to replace my valve cover gasket.

[@pinpom774]

Thankyou for every video you make and one favor can you make video how to replacement steerent rack and pinion please

[@juanchoman9824]

Should you clean the inside of valve cover?

[@epicraptorman]

I change my oil frequently, so the oil is clean. But I can tell there's oil on top of the valve cover not necessarily seeping down

[@mrbriceno3949]

Amazingly detailed im convinced i have a leak .. im getting random misfires on all cylinders clrsned egr calve and valve cover from cover worked well for 5 days but misfires came back.. anyeay i will replacing manifold and cover gaskets

[@RadBadBoys]

Do you need a torque wrench to reassemble?

[@russoft]

noticed the oil because it killed my alternator. Didn't realize the rough running engine on idle might be related to the leak too. Guess this rose to my #1 "to do" item for my vehicle.

[@ryhu5642]

Thankyou you just verified my problem. Was making my car misfire also abit of coolant I was loosing. I need to check my oil level aswell tho🥺

[@willzavala9890]

If you're losing coolant you might have a head gasket leak and that's a completely different problem.

[@PlatoonGoon]

Top notch, thanks for making this.

[@Bula_bk]

Any one know if a bad valve cover gasket can cause a whistling noise if it’s warped or something

[@ricardoperez8879]

Thats bogus how people liked this comment but no one answered....including me

[@thenurseadvocate8799]

Yes! It sounds terrible

[@alexandercano5314]

Is there a video of how to change valve cover gaskets on 2014 chevy silverados?

[@kenricktaylor1683]

Hey I appreciate that I was wondering if I had to drain the oil...

[@Mr2pint]

You were doing well until you didn't mention the use of torque wrenches and cleaning of surfaces for installing new gasket. You will probably have people who just watch this video throwing it all together and having problems very early down the line.

[@1AAuto]

+Mr2pint Great tips that we overlooked when putting this video together. We actually have an in-depth install video for this part. This was meant to be a quick overview of a valve cover gasket failure.

[@kyera1855]

I have a bad oil leak in my 06 jeep grand cherokee 3.7 on passenger side. It had overheated 4 weeks ago and been sitting. I replace the radiator and thermostat and starter because it was having problems starting and noticed oil leaking when I tried to start it. There is a knocking sound and had someone read it and got the code p0300 but then I noticed a large crack in my valve cover. Do you think the car is worth replacing

[@likkaweyy]

@1Aauto do you guys carry the cover gasket? I’m looking threw your website but can’t find it. I have an 06 civic

[@db4652]

Good video 👍🇲🇽

[@titanmasterrace4000]

1;52 now i know what's it's called i got a big spot of oil on the exhaust manifold time for a new seal but is it safe to clean the manifold?

[@brentparsons2661]

Titan Master Race it should be as long as the engine is completely cool. Use some brake cleaner. If the engine is not cool, the cold cleaner might crack the manifold

[@rogeryanez8107]

Will a valve cover gasket not sealing properly cause a obd2 code?

[@KingPOF]

It could yes

[@ChickenStank]

I noticed a burning smell lately checked under my hood and though it was already leaking very slow all around it, now I noticed it’s sputtering out at a seem onto the exhaust yikes

[@tnamen1307]

Very nice video.

[@1AAuto]

Thank you~ +Thang Tons

[@tamyboy1]

Great video, thanks!

[@timothytucker76]

will this cause heavy smoke from the pipe and engine

[@somewhere-n-Texas]

Yes it will

[@theflame45]

Thank you so much that was very helpful.

[@Mythbusters1898]

What about rusted bolts? What do we do to get them loose without breaking?

[@1AAuto]

You can try some penetrating oil and see if that loosens them. Thanks for watching! +Timelord1965

[@rightyouareken7587]

Seat the socket all the way down on the bolt and even tap with a hammer. For Phillips make sure you are using the right size head and seat it as far as you can by tapping with a hammer. Try using an impact gun as well. Penetrating oil the day before the project and 10 minutes before.

[@Darkhunter218]

50/50 mix of ATF and pure Acetone in an acid resistant container or metal container, cover your seized nut and allow to drip down for awhile, I did it 2 or 3 times then was able to finally break loose a couple of seized and rusted up bolts that were holding on my EGR

[@troysmith749]

Could the leak have been caused by a warped cylinder head or block with no overheating?

[@prezaricardo1749]

Thanks nice video// I will do mine this sunday looks very simple, I guess it is only follow step by step.

[@mubashirkhan8779]

Due to bad over head cam gasket ..engine overheat or not

[@elypeachy3296]

Thats a very roomy bay, which toyota is this?

[@TheBlairWenchProject]

Why can’t I find a video with the noise the car makes when it needs one? I just wanna know if the sound I hear is related

[@annamika5461]

It’s usually a sputtering sound. Decreased power mileage etc

[@joaquinjr3488]

It’s oil all around mine and I’m so glad that was one of the symptoms. It’s black smoke coming from the engine and it seems to burn though my vents. Am I still on the right track anyone?

After a tune up of a 10 Dodge Journey I have white thick smoke coming out my exhaust and no oil in engine what’s wrong

[@mikereiffin4618]

And tightening the hold down bolts to squeeze what looks like a still good gasket does what..?

[@steevesmwangiis1836]

I'm Steve I would love to add something maybe can help someone if I had known earlier I would have saved a few dollars before changing the gasket I had a problem with spark plug rings having oil I changed the gasket nothing changed I changed the pcv valve and the problem was solved

[@RickyPisano]

Try it on a Ford Duratec DOHC V-6. Can't even see Bank 1. Not simple by any stretch. But thanks for the info.

[@1AAuto]

+Ricky Pisano Thanks for the feedback!

[@PartyWolf36790]

My rav4 also has this ...... Butechanic said nope it's fine , sluggish acceleration , rpms drop, clunking in my front and exhaust rattling . Suv was taken to Houston and back and problems arose after 2 trips :( no one knows my issue for sure.

If a mechanic is repairing a valve cover gasket shouldn't he also check the oil pressure sensor also?

Thank you man you nailed it

Hallo sir my Chevrolet optra cover valve gasket start leaking too soon . Have to change every 4 months . Gasket + plugs + wires. How to fix it permanently

[@gregorland1697]

My 99 Cavalier engine code 4, 2.2 inline four-cylinder symptoms are P0300 (random misfire), spark plugs are carboned up, oil in spark plug holes, valve cover leaking oil, after long idle engine dies when stepping on gas. Upon restart lots of smoke comes out of exhaust. Reving engine clears up rough idle for a while then engine starts idling crappy and dies. Could it be a bad fuel pressure regulator or a just a bad valve cover gasket? Or a bad throttle body? Or a bad PCV valve. Car has 172,000 miles. My fear the most is a bad head gasket or cracked aluminum head. No visible loss of coolant observed. I will start out with the PCV valve and then replace the valve cover gasket. I will be checking for a blown diaphragm in the fuel pressure regulator. All this work might be for naught if the cylinder head is cracked. Ahhhhh I need the girl from Ipanema to help me fix my Cavalier. Long and slender she can reach in and get to the hard to get places.

[@brianclark1858]

my cover gasket has been replaced 3 times and also the valve. it continues to leak oil onto the engine and causing smoke and burning smell. is there something terminally wrong if oil continues to leak?

[@1AAuto]

+Brian Clark We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1AAuto.com

Cool video

[@abramporras7877]

That looked easy thanx

[@vongsakra253919]

Toyota makes the most plastic beautiful cover of all.

[@dreday7590]

What if its leaking from the back of it is that a different gasket in the back

[@asherq8646]

The gasket goes 360 degrees around the valve cover. If it is a vertically opposed gasket on the back of your engine, then it will be the intake manifold gasket, however, this should not leak oil.(to my knowledge)

[@curtisstewart83]

Nah same gasket

[@yourlocalemoboy5985]

Mine keeps dripping onto my exhaust (98 Corolla) and evaporating so it looks like my engine is on fire when I finally stop or turn off my car. I hope to get it to a mechanic on Monday

[@lebeckchris]

Go to youtube channel fordtechmakuloco, he explains why this happens on fords. I can't remember exactly why he said this happens, but it wasn't nothing to worry about on the fords. The video was called something like oil pudding.Also he is the best mechanic i have ever seen, he is a master at this stuff. He is very good to learn from, his explainations make doing car jobs almost dummy proof. If you check him out tell me what you think, you won't be letdown i guarantee that! I started working on my car because he made things seem so easy, and breaks down every possible scenario so when problems arise they can be quickly dealt with.

[@tavnikcity6504]

It’s just condensation man,don’t worry it’s typicall in some engines.

Good to hear this Toyota used the same metal as the engine unlike Mopar. They have iron blocks with aluminum heads. Makes no sense.
