Anyway the engines of A-164 Wipeout are not visible from first person, but the heat haze from engine is. So I think this should be fixed. Please see the attached video, the heat haze from engines can be spotted from 0:17:

I used the Head Range Plus mod, so I could display the problem more clearly.
