Could also be some slight piston slap. That's also usual for this engine.rochversa wrote:When my Versa SL engine is cold, it makes a loud noise that sounds like a valve lifter. The noise goes away when the engine is warmed up, but it is very pronounced and almost embarassing when the car is cold. I took the car to a dealer and they said the oil pressure was good and that this noise is symptomatic of this nissan engine.Is anyone else experiencing this type of noise?
i changed my oil and the knocking got a lot fainter. barley notice it nowsilverarrow27 wrote:Could be your oil.
Most of the time, it has to do with the viscosity of the oil you're using. Usually when it comes to valvetrain noises, oil is the first culprit; especially when it's normal valvetrain noises.#1Tango wrote:

Any reason given for the low pressure?rochversa wrote:Just wanted to post an update...I left the car with the dealer and asked them to listen to it in the morning and if they could look me in the face and say 'this car engine is working and sounding as designed'...then I would not bother them again. When the service manager drove it in the morning he said something is not right with this engine. They consulted Nissan tech support, and after discussing some measurements and pressure testing (#3 cylinder had low pressure)....Nissan said they would replace the entire engine (everything except intake/outake manifolds)...the engine came in today and they will replace it (at no charge, car only has 26,000 miles on it) over the next two days. I've had a lot of cars and this one was too noisey...good for Nissan for standing behind their product.
wow! wow! wowrochversa wrote:No idea. The dealer did not diagnose, rather, they called Nissan factory techs and the factory told them to make certain measurements (in the valve train) and to compression test the cylinders. When the dealer called the factory, the factory said 'OK, we'll send you a new engine." I asked the dealer if the factory would tear down the engine and if there was anyway I could find out exactly what the problem was, but they said the factory only tears down a sample of engines and does not report back on them. It would have been interesting to know a specific such as the valve stem on one of the valves to the #3 cylinder was bent and was not closing properly....but, it looks like we'll never know the exact problem...the engine arrived today, it is a complete engine and they said they need two days to remove and replace it.
OH boy mine is noisey too I am pretty close to the same mileage as well.nearing27 wrote:my car has the same problem . after months of telling them it about the loud noise on cold starts they kept it over night to hear it but they told me that they recorded the sound and sent it to the factory techs they said there was a problem with cylinder #3 and they replaced just the block .
my car for most of his life has been parked underground. The engine noise changed at 15, 000 Milesfba123456 wrote:I noticed this also, but I'm not sure if its the same as what you are describing. This started when I began parking my Versa outdoors.
I'll talk to the service tech when I get the car in for service.
scottneon, where is the dealer you took your car to? I`m close to waretown, there aren`t many Nissan dealers this way...Scottneon wrote:Just wanted to let the other Versa owners know. They had to replace another engine at the dealership that replaced my engine. They have a problem with them. I don't know how bad the problem is but this is now 2 engines in NJ that I know of
