I bought my Craftsman pressure washer 5 years ago and I noticed last week it was leaking oil from under the valve cover gasket. It has the Honda GCV160 on it. I never worked on a small engine before so I went straight to Youtube for some help. After watching a few videos it looked like the leak wasn’t from the valve cover but the little O Ring on the cam wheel pin that sticks out the bottom of the head. So I ordered a new O Ring and valve cover. Most people said to just buy another $6 valve cover because you will probably bend the original one getting it off because they use liquid gasket at the factory.
The replacement went well and the O ring didn’t look deformed or torn, so I don’t know how oil was seeping past it. We will see if my repair works after the RTV cures and I put oil back into it. The one thing I was surprised about how people were saying that these Honda engines always leak oil. This is my first small Honda engine seeing my past lawnmowers always had B&S engines.
