Porsche 914 engine fan, Engine Fan Air Intake Screen? Options

[Str1974]

Hello All, I've currently dropped my engine (Yes, my first time on my own..) in order to replace my oil cooler and clean up my engine tins and repaint, etc. I removed my engine fan to clean up as well, and was wondering why the 914 engine does not use the intake screen that other type 4 bus engine uses? I realize the bus engine has it that it is accessible from rear engine lid and therefore you don't want to loose your fingers by sticking your hand into the fan.... but other than making it harder to replace the fan belt from the back of the 914 compartment, has anyone decided that in order to prevent a wrench or other tool fall down the back of the 914 engine compartment and get feed into the fan the screen could protect accidents from happening. Any thoughts? Any reason for the screen to make any negative cooling effects on 914 fan intake? Just curious and thinking about putting on screen....
