i did a mini swap.. never got the vtec to work..(had to buy a oil pressure switch...had a problem wit a few other crap vtec related but anyway) FINALLY got the vtec to open up a few times and now it sounds like theres something jumping around in my cylinder head. so i took the valve cover off inspected it thoroughly and still nothing to be found. put everything back together sameeee sound.. like something is jumping up around in the head and getting slapped around by a rocker or something. i did valve lash so i know its not a valve tapping or anything.... anyone had this problem before?? any suggestions?
