Valve cover nut WASHERS?

Postby INSUBORDINATOR » Thu Mar 10, 2016 1:20 am

In my recent hunt for oil leaks, I JB welded a casting flaw underneath the rocker box area of my left head - tricky but successful.
THEN I noticed some oil malingering in the valve cover bolt well. My 2002 750 Tourist has attractive squared of acorn nuts & little silver steel washers - which apparently let some oil through. Was there ever a rubber or fiber washer beneath the steel washers ? I have seen washers with rubber bonded to one side. Any body else having oil sneak by the valve cover nuts? Did anybody bother to address this ?
Close to being oil tight & hope to succeed.
Thanks, C.

Only the metal washers on a 2007, nothing else. But I would think that oil would get stopped from leaking from the inside gasket. I've never had any oil leak as you describe. My original gaskets were replaced with the silicone ones many years ago. And I just changed to new silicones last Summer. Seems like the gasket surround that would circle the nut & washer is all your need.
Have you tried to justcut your own gasketing from perhaps material just a tad wider? Maybe some of the new ones just aren't like the ones offered when you rig was new. That has got to be annoying.

Yes...minor oil weep... Got some copper washers from Ace... They squash a bit...once I had one squash so much it caught on the threads of the stud and made removing the cover a bit more of a challenge... Other than that they been working fine...

I had some minor weeping on my 650 in this spot...I guess I just thought WWID on the spot and put some O rings on the stud and installed the valve cover nut. No problems since. I haven't removed the covers since but would consider the o-rings a disposable solution.

My right cover leaked from there, not much but did. I just replaced washer with new one and no more leak, no rubber washer or anything just a stainless washer ---Thanks Terry Crawford! :cheers:

Just the usual amount, nothing unusual. But I use synthetic oil which is harder to confine, which may be why it lubricates better.

My 650 does not leak. I agree that the gasket surrounding the stud should seal out oil. But if your still wants to weep, I'd get nylon washers. They seal as well as copper and can be used over and over before needing replacement. Hardware stores normally have a selection in those little cardboard drawer assortments of nuts, bolts and various gizmos in the hardware section. Love that section.

I'd say a couple of tsp, come out when I remove the valve cover. A bit is trapped behind the bottom lip of the gasket - I never measured.

The drain hole in the head gasket is definitely in the right place & not blocked. after I installed it I poked a long rod trough to test.

I had one leaking, found that the stud was too long on one side, I had to use a nut under the acorn to get it tight enough to stop leaking.

Thanks to my Friend GLENN here on the forum, who turned me on to a pair of rubber clad Sealing washers. No more sneaky leak.
