ok, so the 7afe head uses a different style of rocker arms, right? my head has a real bad tick when i shift a certain way, when i hold the gas half throttle, or when im accelerating over 4500 rpm. anyone ever had similar problems?

Actually, it depends on the particular brand and model of engine, there are lots of overhead cam engines with rocker arms, single overhead cam will almost always have some type of rocker setup. My wife's 280SE Mercedes was double overhead cam with rocker arms...all depends on the engineer's design... The double overhead cam 5SFE and 7AFE do NOT happen to have them. They use shims between the cam and valve tip, pull the valve cover and use a feeler gauge to check the clearance, easy enough to check, you can copy the procedure from the library ref manuals, have to pull the cams to change shims if they are out of spec on clearance...I'd invest in a new valve cover gasket and check it myself, if it needs adjusted, you can always take it to the shop if you dont want to do it yourself. As far as the noise, thats a good possibility, could also be a loose heat shield, or pinging from low octane fuel. or any number of things... |
