Valves at 167.000 km
Took the car to replace the PCV and this is what the mechanic sent back, saying he strongly recommends I let him clean the valves. Says he has to order some spray cans and that he has done it before. Only risk he said is that he needs to change the oil after.
EDIT, forgot to add the question: could this be from the bad PCV or is something else that needs to change (gas quality, driving style ?)
