Ok, so I have posted up a good del about my wife's car and how I determined it had piston slap EVEN when the dealership attempted to tell me it was normal or just valve chatter. I wont go into detail about myself however my automotive skills are very extensive and quite sharp. I just want to give more people peace of mind and the knowledge of knowing if their car is as designed or if a problem exist. I have used this test for the better part of 10-12 years now. 100% of the time it has worked flawlessly. If you suspect your engine to suffer from piston slap, perform the following
Start your engine up after sitting for awhile (best overnight) and let run for 15 seconds. memmorize the severity and sound of the noise
Immediately turn the car off, remove all the spark plugs, and with an oil can squirt 2 squirts of oil into each cylinder, reinstall plugs.
Start the car and again listen to the sounds....IF the noise is greatly reduced OR gone all together, guess what, your engine has piston slap.
Because this is just a test to determine the results, the noise will return after about 15-20 seconds, and as usual not go awya until the engine warms and the piston expands which prevents it from slapping sided to side while it is also moving up and down.
Lmk what you guys come up with. I dont often offer my advice like this however I feel this may benefit quite a few members on here that are either not sure about the noise they hear and are worried, and or the members that are being lied to by their Nissan service dept.
Sincerely, Lawrence
