The TR7 has such a system. It is to the point that if you remove the oil
filler cap, the engine will die immediately. This also makes for a good
way to check your rings: If you'r rings are worn badly, the engine will
keep running, because the blowby is greater than the vacuum through the
two approx. 1/2" dia. lines! I found this out the hard way. :(
