What is wrong with pushrods?
>>14814093
Nothing.
>>14814093
Nothing
nothing as long as they have 4 valves per cylinder
>>14814093
they look fine but take them out and inspect them.

That's just a picture off google, I'm asking what is wrong with using pushrods in an engine

Nothing.
>>14814093
They bend too easily.
>>14814124

I know this post is probably bait, but in the slight chance OP is serious, here goes.
Pros:
>Only 1 cam required for all configurations; inline or vee.
>Smaller heads, which means less overall volume and weight compared to OHC engines of similar displacement.
Cons:
>Generally limited to 2 valves per cylinder, meaning optimum airflow cannot be achieved. 3 and 4 valve iterations exist but complexity rapidly increases with each valve added.
>More mass must be shifted to actuate pushrods compared to OHC. This increases complexity and the risk of valve float, limiting maximum RPM.
>Heads must be designed to accomodate for pushrods, which limits the areas where valves can be placed and restricts the amount of porting that can be done.
