i'll be dropping the information we have gathered over Dec 2021 in with a set of posts.
the material was prompted by mr b ( @JeffBowlsby ) who observed that for the 74 MY there was an EC-A and an EC-B engine. mr b's thought was that the EC-A was a 49 states car and and EC-B was a californian car for emissions. mr b's view was rational and reasoned. 73 EA engines are 49 states. 73 EB engines are california. 75 engines are documented in factory literature as EC-a (49 states) and EC-b (california). the logic should follow? BUT as per the mystery of the 914, the truth about 74 1.8s turns out stranger than fiction (or common sense?). the material is not necessary to running a 1.8 or having fun with a 14. (IMG:style_emoticons/default/smile.gif) its for historical purposes and as information to 74 1.8 owners to assist with restoration if they want it. |

also that yellow car is one more confirmation that porsche did indeed change the plumbing to the charcoal can with the move to the engine bay.
got the same S curve hose from the fan to the single nozzle end of charcoal can as mine (and starbear). thare have been some inaccurate hose diagrams floating around for 1.8s for years that have had that wrong. not that it matters a huge amount i would think as the whole charcoal can is a bit of a joke when you look closely at it and how it works. though mine has been working beautifully for at least a year now. it spent the first 12 months or so after i reactivated the car from its long sleep stinking up after a week or so. but now. no stink. its been getting enough drives over a long enough distance to purge. i guess the charcoal is still in good shape in mine? |
