Engine number missing on my 75 914 2.0 Options

[Junioren]

Good morning to all of you readers.

I recently imported a 75 2.0 914. VIN and chassis numbers have been located and seem in order, however I am unable to find the engine number in its usual spot.

What could be explanations for having an engine without an engine number? When engines were replaced by VW/Porsche, would these new engines possibly have no number on them?

Thanks,

All of the Type IV motors have bottom-side exhaust ports. That's one of the things that makes them a Type IV motor. The pre-72 Buses that have exhaust ports on the front and rear sides of the head have Type I style motors, not Type IV.

The plug angle already says these are 2-liter 914 heads. It is possible but very unlikely for someone to use those heads on a smaller-displacement motor. You're probably OK to assume the engine is a 2.0 one. If you really want to be sure, you can find someone to "pump the engine" and measure the air flowing into or out of the engine through a complete combustion cycle. But I wouldn't bother, myself.
