Are there engines with a not removable head?

>one-time use head bolts that take their name a little bit too literally

>plastic clips
>can only be removed by breaking them

some types of flat head and only a few ohc

not at all. Plastic clips can be removed without breaking either careful with two flat head screwdrivers, or pic related, with a special plastic clip removing plier

>have to take the bumper off to replace headlight bulb
clio/megane?
a friend once asked me if I could help hime change his bulb, was really pissed when he showed up in a clio

it does mean you have to take the engine apart from the bottom up tho
would work in well with a split crankcase lmo

>need to do a small fix
>have to take apart the whole fucking car to get to the part that needs fixing
REEEEEEE
