Suzuki - 09280-17002 - O RING SEAL NUT Leaking Possible

[Badooka]

Just wanted to know if anyone has ever had these leak and if they do where would the leak show itself at?????
This is the o-ring on the two forward head bolts.

IIRC someone said if those leak it shows up as a leaking head gasket??

I'm not sure if it's the valve cover gasket behind the front or those leaking-
the leak forms right at the front of the head where the head bolt is upside down- Hard to see in that deep- I doubt seriously the head is cracked-
I figured I]d change these again when I replace the valve cover gasket-
I'm having no luck with this silicone valve cover gasket.

My 750 is leaking a bit down there. It's showing mainly on #4 pot, one fin down from the top of the cylinder. It's only just misting so I'm not bothering to have a better look until it's valve check time again.

It is very common for those o rings to leak, especially if they are 30+ years old.Shows up as an oil slick on either side of the cam chain bulge in the front of the head. Simple to change. Set your valves while you're in there.

what he said.
I eliminated front engine leak with this simple fix. (apply grease to the o-rings when installing)

That's exactly what it is! little tracks down both sides of the bulge-
I knew it had to be those o- rings- I did change them on rebuild but did not grease them- maybe they rolled.
Yep gonna re-check valves and re-torque all the head bolts- hopefully this is it on this girl!
Me hates any leaks!

I'm having great result with Z1 valve cover gasket too.

I checked Z1 with the new web site, they don't have any valve cover gaskets for my bike. Found an OEM in Ebay for 10 bucks.
Chucking the silicone from the TN manufacturer- keeps blowing out.
