Has there ever been a reason Porsche/VW speced L-jet injection for the 1.8 engines instead of D-jet like the 1.7 and 2.0 engines used?
Usually when manufactures do this there are financial reasons for the change. Either they have the same engine on other vehicles they produce, or its just cheaper to use whatever part is being used. But Porsche didn't use the T4 motor on other cars at the time. And if it was cheaper, they would have done away with Djet on the 1.7 and 2.0. I don't think VW was using l-let at the time for the bus... but maybe? There has to be a reason that Porsche wanted Ljet on the 1.8. Zach |

I can see why they left the vacuum hose on the advance side of the vacuum advance/retard unit on the distributor and tucked away for CA certified vehicles because as the ignition curve advances it increases NOx. Being in CA their emissions standards are nuts so 1st thing to go after would be NOx and then HC and CO. So I don't know why mine was reconnected by whoever connected it onto the second port on the t.body.
