Yes. this one is air cooled. So no chance of coolant due to a cracked block...no? mmmm don't know then.

Has this got Jet-tronic injection? or Bosch? anyways, there is a fuel pressure regulator what may need your attention.

...as if??? anyone would be so INTIMATE with the Jetronic to be able to explain each of these component function. This could be this weeks GURU QUIZ??

I think this is what makes a Porsche so expensive to diagnose failures.

somehow I'm their number 2 porche 914 expert....just 'cause I knew about the jet-tronic from my Datsun and 88 Quantum too- Love these cars, not as much as hamster, but have only a passing knowledge, as my buddy with the 914 has it NOT running more than he had the thing running- THB, you're leaving me with my union suit flap undone and all the vulnabilities exposed, a "howdoo" ==good job dude, would be nice. You could be a robot.
