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?

i don't think that is entirely accurate but it may be..
according to PET the 75s start at EC037552. i don't believe they built 12,000 75 1.8s. could be wrong. but pet says 76 1.8s start at 045....(ie which is where 75s end). and as far as i know there were no 76 1.8 (but what you posted implies a handful) and nothing else VW had the engine in 75. so on that basis it ends at approx 45,073 engine units (IMG:style_emoticons/default/confused24.gif) either what you have posted is wrong or the PET is wrong. which still leaves a mystery. a 49K engine number? mis-stamped at the engine factory? or - are you sure it says 49 and you are not misreading 45. wouldn't be the first time someone has come across that sort of mis-stamping/numbering. been detected in VIN sticker recalls for instance. |

What a trip! Heres a photo of the case in question- looks to definitely be an EC0049 Im stumped! Wonder if it came from a non 914 type 4 case? Hope there is an answer out there somewhere!
