Nissan Murano

Hello, I wanted to know if it is true that washing the engine internally based on some chemicals can there that the car no longer gets oil smoke, this fault only does it in the first start and the mechanic told me that washing the engine is removed .... greetings.

Hello, the mechanic that advised to do that of the washing is not successful. First if when it takes smoke it would be of two types white or white bluish. If the smoke whenever you tear by car both in cold or hot and it is blue it can be valve seals, seeing consumption of change oil in exchange.Is when starting by car in cold Heating or that the hydraulic taque fail in cold because the degree of viscosity of the oil is very dense for example, if the vehicle has to use a SAE 10W40 and made a 20W50.Irary of great help to know how many kilometers the engine has, if it consumes oil and how much if it starts in both cold and hot it humans if it fails when it starts, if you move when you circulate. To remedy it and less in a new car. A greeting.

That mechanic is not right when it is white only when starting, it can be the valve capuchones if it is black when lighting an injector is being open to the fierce gas so when it is when it smokes by oil there are no products that kite it and the ke kita does not take it away.

Ok thanks to both for their comment, and they are very right, the mechanical the only thing that iso was change of oil and apply a liqui Moly to seal, the fume is going out and I will take it to another mechanic who tells me about the valves

hello, good afternoon.
The comments here are always going to help you try to solve a problem. And as before they call that it is necessary to know more less the mileage of your vehicle because perhaps the problem caused by smoke is effectively the vents of valves that have already lost pond in the valve, but if your engine has an extensive route, the valve seals may have failed due to excessive wear between the valve guide and valve itself. So what will happen if you change only the valve seals? Evaluation and tell us.
luck............
