Hello!! today I have installed a PF nock in my ADZ engine together with my buddy. 1.8 liter 90 ps. when we took off the lid, glued a very large amount of oil carbon and so n shit. the previous owner has always driven very slowly and sensibly and has the motor so really nice. now my questions: do you have to introduce the ignition even further with the PF camshaft? if so how much in about? it could be due to the not adapted ignition that I from the n does not so much notice? does someone have advice? 2nd question: since a lot of redness has stuck on the top of the valve cover, I think the engine doesn’t look much better from the inside either. how can I get the reasonable clean? he already has new oil. injection cleaner from LM I have already taken and valve cleaner from LM too. does someone have advice? find it funny that the guy pulls off so badly.. if I look at n vento with ABS engine like my colleague drives him, but he drives me in g round and floor. and this is original.. my car with changes is located at the bottom of the SIG. if questions should appear.. please help me!!
