oil leak timing covers

Postby robertdawber » Mon Mar 14, 2016 9:55 pm



I have tried everything from replacing the gaskets, after market and the Honda, tried a different set of covers, they still leak.
One side it leaks by the odometer cable end of the cover and it's not clear on the other.
Any thoughts?

Are we talking timing belt covers or valve covers.

Valve covers. Both sides.

I had the same issue on the left valve cover. I was not losing oil, just an annoying seep that I thought was the oil seal which I had just changed (just made my riding boots dirty. It's amazing how much mess a half drop of oil can make). Wingadmin gave me the suggestion of cleaning everything up and use talcum powder to locate the leak. That trick located the leak quickly. It was the valve cover gasket, also just replaced. When I took the cover off I noticed that there was some varnish build up inside the gasket channel that I think was not allowing the gasket to seat properly. I cleaned that up very well and reassembled. So far I have not had any seeping issues from the gasket since, so that may have been the issue.

There is also the possibility of cam shaft oil seal leakage. If they seep oil it can migrate down below the valve covers.

I did check and replace the cam seals. I cleaned the covers so well the second time around...I did not do the powder test. That is an idea!

did you replace the rubbers under the valve cover bolts? if they are old and squished out then you will not get any pressure on the other seal. The bolts only tighten up until the shoulder bottoms out. See if yu can spin the grommets when they are tight. 8-)

Reaching here but...... My Honda manual says to use a sealer on the outside edges of the seal when replacing the cam seals. I'm guessing that since the seals are "clamped instead of pressed" in is the reasoning behind using a sealant. In other words they may be leaking from the outside edges and not the inside. Did you use a sealant?
