Can someone tell me what this is?

Think I found my leak. There was a garbage homemade looking fiber gasket here. Problem is, I don't know what this is in order to search for a new gasket. Thanks in advance, GWD hive mind!

partzilla is my friend, most of the time. Discovered another fun flaw today, there's a decent piece of the cylinder head cover broken off near the front rounded piece. Partzilla shows that those are not available any longer. I found some on ebay, but they don't look the same as the ones I have currently. Were there two different styles of cylinder head cover for the GL1100?

valve cover ? i know there were aftermarket versions, don't know if factory offered more than 1 style.

Yeah, valve cover. I've seen the same thing referred to as both. Though I was looking through some pictures trying to figure it out, and the valve covers on my bike look to be the same ones from the GL1000. Do you know if that was basically the same engine? Or maybe someone at some point put a different motor in it? How would I tell the difference?

Can you post a quick photo?

Here's a close up of the valve cover...

The missing cover is the timing belt cover for the right side. The timing belt cover gasket P/N for the right side is 11831-371-010. The valve cover gasket P/N is 12328-371-000

Yeah I have the timing belt covers and gaskets. The question is that valve cover looks like it's from a GL1000, my bike is supposedly a GL1100. Are those valve covers interchangeable?

I don’t believe that is from a 1000, but an aftermarket 1100 chrome cover.

That's not a GL1000 valve cover. It's an aftermarket valve cover made for the GL1100. Originally they said "GOLDWING" on them, which is the dead giveaway, because Honda always has a space in there. If it was OEM, it would say "GOLD WING" not "GOLDWING".

Thanks for posting this, i have the same on my `82. I`m not fond of them, they leak constantly even with new seals. If a reader has a set of original Honda covers, feel free to contact me.

I just found a set on ebay for $40. Looked like there were a few sets around that price.

Okay. New development. I'm fresh out of ideas at this point. New (to me) valve covers, off a stock 82. New gaskets. New final gear gasket. Fresh oil change. Took her for a spin around the neighborhood and my shoe is still wet. Left side is fine. Right side still leaks. Not gushing, but definitely splattering. What's the round piece off the back side of that part of the engine? Could it be coming from there?

Oh, and fun side note: somehow I developed a backfire.

Are you talking about the fuel pump?
The wind from riding makes it hard to say where it's coming from. How about just running the engine stationary on the center stand, and then it might be more clear where the leak originates.

Alright, did that, and found that the leak is coming from the insulator between the fuel pump and the engine. Really tough to find though, only found it at one website. It's supposed to be hard plastic yeah? Is there any disadvantage to helping make that seal with some RTV Black?

Rambozo · Post by **Rambozo** » Thu Jun 17, 2021 9:14 pm

I believe those insulators had very thin paper gaskets on each face. Either make some new gaskets or use some sealer very sparingly would be ok. But first I would remove any old gasket and take some 400 grit wet dry sandpaper on a piece of plate glass and wet lap the insulators flat.

I just looked and amazingly one of them is still available from Honda.
