Basics of driving manual 1 no memes trolling copypasta or low quality pros and cons of ohc engines vs pushrod engines yeah ive always thought it was the opposite ohc engines peak tq lower rpms pushrod peak tq higher rpms for example the pushrod 57l v8 in my truck makes 408 tq at 4200ish rpm the 57l v8 in the toyota . Ohv valvetrain components tend to be cheaper to make than their ohc counterparts but there are also more moving parts furthermore as the cams on an ohc engine are up top lubrication becomes a design concern whereas the lower placement of an overhead valve cam keeps it lubricated at all times. The differences between dohc sohc and ohv or pushrod valve trains is explained how the valves are related to each and how each works i will also speak of advantages of each of the valve trains. Ive always been an ohc guy learned on them and they were the only type of engine i wrenched on i still prefer ohc but i sure love how simple taking a head off an ohv can be as well as the generally more reliable nature of them chain driven camshaft in the block vs belt driven cam in the head of course thats older stuff. Ohv vs ohc and how it relates to muscle cars today i thought i would write about ohv vs ohc while it should probably be pushrods vs ohc instead i often hear reference to ohv instead so i thought ohv vs ohc was a better fit
