The Toyota 4.7 I rebuilt last year was dohc and it went cam->cap->top of valve stem.
True, some in fact most new OHC setups are that way, other earlier styles the cam actually presses on a rocker arm then the valve. Depends on the manufacturer. I have never torn apart the top end of one of these 4.0 so I am not sure.
Example of a Honda OHC setup with rocker arms
2004 F-150 FX4 Supercab, Dark Shadow Grey, 5.4 liter Triton V8, Flowmaster Cat Back exhaust, K&N Drop-in, Intake "Gotts" Mod, Edge Programmer, 2.5" Level, Front tow hooks, 33" Falken Rocky Mountain ATS
Future mods: CB Radio, Dual band Ham Radio
The older I get the more I realize it is worthless to worry about tomorrow when you are living today. Love your family and friends, live like there is no tomorrow.
