Hi--
My spring project is to put fuel injection back into my '73 1.7. There's a piece that I can't seem to figure out how it fits into the mix--it's on the drivers side and looks like it goes into the fan housing? It's got three inlets. Any help would be great--Thanks! Here's a pic:  |

What can I say Cap'n? There was never one on my original car - early 73. Certainly they can be removed at any time but my car was pretty new when I bought it. Brad Anders' research seems to support that as factory original.
. QUOTE Porsche used a PCV valve on some 1.7L and 2.0L D-Jetronic engines, mostly in the 1973 and 1974 models. Early 1.7L and late (1975 and 1976) 2.0L engines did not have a PCV valve, and the crankcase breather on the oil filler was connected to the air box. http://members.rennlist.com/pbanders/PCV.htm Further supported in Haynes. I do stand corrected though - most 73's would have the PCV. What would be the technical relationship between the vent on the head and crankcase? The PCV deals with relief of blow by gasses - do those gasses also make their way to the rockers? |
