Is this gasket including Cam chain tunnel seal ?

Hi,

I ordered a full kit from this place https://yambits.co.uk/advanced_search_result.php?keywords=GSF059 And i can clearly see the Cam chain tunnel seal in there but when i received my kit it seems the seal is within the head gasket itself.
Could someone confirm this from this photo?


Thank you very much !

 

With further search it looks just like the athena kit https://www.officine08.com/p80519_engine-gasket-kit-yamaha-xj-650-athena.html which is said to be also "full rebuild" kit. I just want to make sure this head gasket is enough so i can do the valves and put everything back together

 

It looks like the seal is in the gasket. You can e mail Yambits and ask them to confirm this if you want but as it is a full rebuild kit you should be good to assemble the engine l believe.

 

Thanks I sent email to them !
Indeed it feels like all in one

 

Thanks all for the help on this. It seems the kit provided everything I need. Yambits was super helpful.

I have a final request for you pros out there.
Should I use and kind of gasket sealant for the top part ?

The end plugs (half moon plastic) I could reuse but they would need some sealant under and I was wondering if you guys do that or add sealant also with the gasket. Local shop sells sealant resistant to 200 degrees. Loctite brand.

Go down to valve cover prep. Better to do it this way.

I used a little Loctite SI 5980 on mine, worked fine. Do you have new rubber washers for the cam cover bolts?

 

ok cool, thats clear. I dont have this model of engine. Mine is the european 4K0

so the red tacky thing also acts as sealant. My valve cover isnt very flat ( The gasket surface ) but i dont want to sand it as i want to avoid metal particles into that area. So i hope the extra sticky thing and new seal will do.

 

I have access to this https://www.permatex.com/products/g...tion-form-a-gasket-no-3-sealant-liquid-16-oz/ this https://www.permatex.eu/product/supra-blue-gasket-maker/
And this https://www.permatex.eu/product/supra-black-gasket-maker/

 

Permatex is fine l would use that. Just use it in the channel of the cam cover and fit the gasket.

 

Sweet, any preference in which model?

I would use the black gasket maker, it says not for exposure to fuel but the no fuel will be in the recess in the cam cover the gasket fits into. It is like the Loctite SI 5980 I have used. I just put a little in the recess on the cam cover pressed in the gasket and removed the slight amount of excess sealant so none of it got into the engine.

 

The new washers for the cam cover bolts if you have them compress the cover on to the head so it should seal fine. Old washers are not so good if they have deteriorated.

 

Sweet,
The model I have (4k0) only has bolts for the cam cover. No washers. Then again I can always add some compressions washers but even from technical data, there isn't supposed to be any it seems.

 

Yes I would leave it the same way it left the factory.

 

Once again, thank you for the help ! It's coming back together this weekend !

I'll keep progress posted
