I measured Compression and two cilinders had almost no compression.
So, I have to purchase new parts (where??) or another engine.

Sorry about the PVC, EGR or whatever I don't understand nothing. \:\( \:\(
I know it have something to do with emmision, but how to connect or check everything is abracadabra for me.
Even with the Hayn** manual, I don't know where what is on the engine.
