I had my valve cover gaskets replaced in my 1996 Lexus ES300 at 46k miles. Last week my check engine light came on and I was told that it was code PO500 by the LExus dealer in Durham NC. They didn't fix anything but told me to come back if it happened again. When the light came on my speed od stop working briefly. So, I not sure what to do about that problem. Also duing the vist they told me my valve cover gaskets were leaking. I checked my old service receipts and saw that the valve cover gaskets were replaced in 2003.They replaced rear and fron valve cover gaskets. Now I'm been told this is the problem again. Plus they told me my cam seals are leaking. My car now has 137K miles. I don't know what to do. I don't know if they are telling me this b/c I am a female and don't know any better.
PLEASE HELP
