I have a leak due to a failed valve cover (VC) gasket and ordered a VC gasket set/kit. All the parts came in and when I laid out the VC gasket, I noticed one side would not lie flat (and can't physically lie flat because of how it was formed/molded).

I emailed BK Honda and sent pics as well. They replied back that "It will not be an issue as it is rubber and it will seal properly." I'm not buying that explanation. Now, I haven't taken the valve cover off yet, so maybe it's shaped oddly and this is just how the gasket is supposed to look. Can anyone tell me if this is how this gasket is supposed to be shaped? In the pics below, you can clearly see one end lies flat, while the other "bows up".

Disregard. I see now why it is that way. Here's a pic from a video showing the underside of the valve cover. You can see one end has a dip that the gasket must be pressed into. This is why one end doesn't lie flat. If it did, it wouldn't fit the valve cover properly.

And if I had flipped the gasket over, I would have see that arch in the gasket:

All good points. Thanks for the tips/feedback. I bought the valve cover set, so it comes with the spark plug tube seals and the grommets on top. I also about a seal puller and will use cloth as suggested. I saw a really good video with the guy showing four key spots where he used Permatex Ultra Red gasket seal. That's what I plan on using. If anyone is interested, here's the video that does a great job of explaining everything involved in replacing the valve cover gasket, seals and grommets:

@midnight witch: What's the advantage of Honda bond over Permatex Ultra Red? Just to be clear, I'm using a standard OEM gasket and just applying the Permatex material in four spots (as shown in the video). I'm not using it all around the cover to create a gasket.

@frogvtech Is hand tightening good enough? A few posts said the torque should be 7.2 ft lbs (but another said 8.7 ft.lbs.). I don't really want to by a Haynes subscription just for the torque spec. I plan on pulling the power steering hose (that just passes over the edge of the cover) to make it easier to get off and on. I plan on just hand tightening the screws for the hose (and maybe using blue loctite to make sure they don't easily work their way out).

I found the following tightening sequence, but to me, it seems like it would be better to flip 4 and 6:

Definitely not using power tools. I've seen videos of people using power tools to tighten the bolts on the valve covers and I just cringe, waiting for them to strip out the bolt. lol

What you suggest is what I was leaning towards doing. I have a small torque wrench, but I think for these it's better to do it by feel.

Why do I need to put the Honda Bond in that entire half moon? I don't recall the guy putting anything but 4 small dabs of the red Permatex on the "engine block" where the valve cover sits, and that seemed to be primarily because he was trying to make sure the "seal" where two pieces of engine that are bonded together didn't leak (at least that was my take on it). Take a look at that video starting at timestamp 7:45. I think what you're referring to is the dielectric grease that he used quite a bit on the seals and the tubes that plugged into the spark plugs.

Thanks for confirming. 👍

Just did this job not too long ago. Your "take on it" is very correct.

Thanks for confirming. Di you pull the power steering hose to make getting the valve cover off and on easier? I think in my case that's going to be the best option.

 

[hikingnut62]

That's correct. I meant disconnecting it from the power steering pump. I did see the other bolt in the corner, so I'll catch that one too.
