14 hours ago14 hr Hi everybody!Nissan Qashqai 2017 1,6 diesel, cvt.About 86000 milesSo the car starts and runs fine, but I noticed a slight knocking upon coldstart. Almost as if the engine is having trouble building oil pressure. For about 4-5 seconds.And I have crankcase pressure opening the oil fillercap + some smoke.So a Pcv problem I thought. Changed the pcv and the knocking upon starting might have been slightly less. But still crankcase pressure.If I disconnect the hose on the pcv and blow in it, there are not resistance. And I can’t find any defects on other hoses.I notice a sound from the airfilter box, as if the engine is sucking air from a leak in the box. Dismantled everything but can’t find any leak.Some oil in the hoses and around the filler cap, but nothing alarming.Haven’t done a compression test as it’s not a high mileage car. Full service book.Drives 40 + 40 miles everyday.Can’t upload film as it’s to big..Anyone who has experienced the same problem.
