Ha, would most air-cooled VW engines qualify for having the easiest valve cover gasket replacement? Just pop off the bales with a screwdriver, pry off the valve covers with the same screwdriver, replace the gaskets, & put the valve covers back on, not even needing any tools to push the bales back in place? No breather hoses or wires to disconnect, either. Good video, always learn something new even though I've replaced many a valve cover on my air-cooled VW bus & my mk2 Jetta diesel.

@mattpolhamus9194 2 года назад

Awesome as usual Charles. Did this last winter on my B6 Passat VR6 and it went great until I used a too-large torque wrench on re-install and broke one of the bolts off in the block. Tried extracting it but no dice. Luckily doesn't seem to be causing any leaking so far! Still a bummer though #sadness

@Patrick94GSR 2 года назад

Couple of general tips: 1. I like to use a brass brush and/or a brass brush Dremel attachment to get all the old RTV gunk off and get the head mating surface super clean. 2. I’ve found that it’s super important to pay attention to the RTV install specs. Some flavors require hand tightening bolts, wait an hour, then torque to spec, and ideally wait up to 24 hours before starting the engine. But the initial 1 hour curing seems critical to getting the best seal. Also Miatas seem super sensitive about what valve cover gasket is used. I’ve tried 2 aftermarket gaskets in 2 years and they both leaked. I’m going OEM next.

@surfreadjumpsleep 2 года назад

thanks for this video. however, there are many videos already on yt on how to do this job. what would be better would be an explain of what might cause a valve cover to leak and what sort of hints you might have the valve cover is leaking as well as what you might expect once it is fixed. I'm a noob, but from what I understand a leaking valve cover might be a symptom of some other problem.. like a clogged PCV or something else.

Hello Charles, I have to replace the lower sump gasket on my Golf 7R. I saw the tip on using a tiny bit of rtv on this video. Would you suggest using a bit of rtv on the sump as well? I am using the same plastic sump and not changing to metal. Thanks and greetings from South Africa.

@HumbleMechanic 2 года назад

I haven’t done that on the sump gasket, and had great luck with it

@laneflips7281 Год назад

I’m hoping someone can give me an answer to this question. Most of the valve cover gaskets I’ve seen for the 3.6L alloytec engine blocks the pcv valve from the crank case on the passenger side, I believe this would negatively affect performance but I assume they did this to prevent as much oil from being sucked into the pcv valve and avoiding extra sludge from getting into the pcv. But I think this actually traps more sludge and oil in the area where the pcv is blocked off from the crank. Do I just keep it this way and clean up the inside manually when needed? Or do I get a gasket that will keep it open to the crank case ?

@JohnDoe-md2sb 4 дня назад

Are you familiar with Toyota engines? I'm about to change a valve cover gasket on a Matrix. Got the felpro gasket and have some Permatex Red RTV high temp silicone to put on the two spots near the timing chain as recommended. You think it's gonna hold? I read on the instructions not recommended for head gaskets so that's got me stressin' a bit for possible leaking. 🙈

@90210sky 2 года назад

You can replace as many gaskets as you want, but chances are the problem is the PCV valve, when it fails gases will look for a place to escape, most of the times it will be thru the valve cover gasket or the crank seals.

@denton8047 2 года назад

You have to apply that green vw “valve cover sealer” to every gasket surface, the head, the valve covers, the air intake, and then smear the side of the engine with a putty knife with the same stuff. Then wait for it to burn off on the turbo manifold so it melts your air intake in Ohio, apply gorilla tape and drive home. Somehow this engine lasted 40k and it still runs, somehow. It’s also like 80k over due for timing (belt, fsi). I think it runs on spite.

why are a lot of people scared to replace them, on there own? I have 2016 Chevy Malibu 1.5 that the pump vacuum pump went out and broke inside, so now I have to take off the valve cover and fish out, we are lucky so far the end of the cam shaft it looks good, so i am fingers crossed here, but i am looking for the circular oil seal i believe is it call that the brake v. pump seat into the valve cover, it got a little scratched up in the inside of it and i feel like i should change it just to keep it from leaking, just to be sure. Any suggestions or help, i've never done anything like this so I really appreciate your video's ,. normally have a mechanic do it but we just do not have that option and its our only car.

Another place to stick some rtv is where the timing cover meets the cylinder head of the seam only if it intersects the valve cover and timing cover. Obviously this isn’t applicable to all engines. Think like on an m5x bmw motor where the top of the timing cover bolts up on a N.V. m50b25 or the vanos bolts up on all the other later ones. Good DIY- ‘valve cover gaskets for dummies.’ LOL 😂👍🏻
