leakin oil out the valve cover gasket.

Well im not sure how this happened. Its not a big deal I prolly can fix it with some silicone. But I did my valves a few days ago, and left the gasket siliconed in, i never removed it. But I took it to my buddies shop for him to torque everything down for me. Now I'm leaking oil out of the valve cover. Im assuming he probably removed that gasket and didnt silicone it down. I didnt realise how much pressure it was pushing oil, i never thought it would be enough to actually leak with or with out siliconing it down. Im not losing a lot of oil but I though id see if there would be any other causes of this before i just throw it back together and it still leak.

well normal practice is to replace the gasket when u remove the cover, sometimes you can get away with reusing but theres no garuntee it wont leak if you reuse is, personally ive had my valve cover off 3 times and never replaced the gasket with no issues

yeah I have also reused the valve cover gasket with no problems, I just clean it and run a fresh bead of permatex around the gasket both sides. It just takes a little bit, not much because you don't want it getting in your top end.

Maybe the gasket didn't get seated back in the groove properly? The only spot where I've put any type of sealer has been just a film on those half moon bits, no leaks.

I didn't know that you can actually reuse the valve cover gasket at all. Thanks for the tip. So I just have to clean mine with permatex, same as you did.

I have to post a warning here, please dont go mad with the silicon, I have a very expensive motor on my bench at the moment that was sent to a dealers for a cam chain change and when they put it back together they went a bit mad with the stuff, then end result was that all the extra dross went to the oil pick up strainer and blocked it near solid so 55 miles later the thing locked solid taking out the crank piston ect and all they had to say for themselfs was you cant prove it was us! although they are the only people to ever touch it untill it came to me to sort it out

They would have had to go real crazy with the permatex huh? i just did this to my wheeler and im sorta nervous that maybe i used too much. i rubbed a thin layer on the the whole left side of the gasket and got very minimal squeeze out on the outside and i let it dry for three hours so i hope its solid enough that none will break off on the inside.

I think that gasket alone is like somewhere close to 30 bucks shipped??

Mine has done the same thing. It gets worse. Mine got so bad that everytime i would stop it'd dripping a little on a my header and smoking.

Same here except mine just started weeping around that area.
I took it off cleared off the white N tacky sealer.
Then smeared just a little little bit of high temp silicone on there.

No problems since. I used the red stuff or the black stuff.
