Curious if anyone could tell me if there is a difference between 1.8 and 1.7 cases if I were to use a 1.8 case on a 1.7 engine?

actually i am looking closer and i just figured it out.
should have thought of this before. they don't put the O in the ECO on the engine number stamps on the case. its something i remember and then forget again. thats actually a really early 74 EC engine. its not 49,000 its 4,900. a lot of lists show that extra 0 right after EC. its on the PET list too. but the stamped engine numbers have one less digit than the list numbers. i think VW optimistically reserved an extra digit in case they made it past 1,000,000 engines. they never did so the engines never got to have that extra digit. but it got preserved in the parts lists and other documentation. |

Doing the lords work! Thanks . That’s really interesting. Sounds like this engine is a bit of a frankenstein, its a 1.7 with the most random 1.8 case on earth it seems (IMG:style_emoticons/default/biggrin.gif) @shivers is it maybe a 2.0 case? I think the 2.0 engine code is in a different location than the 1.8/1.7 |
