Valve cover gasket leaking, HELP!

[ac011]

I bought my 91 NSX 93k to the dealer for a Major services last March. They had replaced both value cover gaskets and I don't see anhy leaking at that time. After 3000 miles, I discove my value cover gaskets is leaking again! With only 3k miles and 1 1/2 years, I wouldn't imagine it's leaking again. I talked to the dealer and they told me the warranty only cover 1 year. Anyone konw what's going on? should I replace the gaskets again?

The first thing to do is check the four cap nuts that hold the cover on. They could have loosened a bit.

These are accessible right in the engine bay 10mm socket will do it. If not, really insure where the leak is coming from, and you may have to remove the valve covers and regasket them.

I have to say that Honda gasketing is the BEST in the business and most of the time, you can even reuse them a few times.

With the NSX you don't have to open them up to much, so I always replace them, since it is some work to do it.

On my Accord, since the job is much easier, I will reuse them once for a valve adjustment. If they do leak, which they have not ever for me, them I change them.
