Nissan Sentra B14 engine failure, motor1.6. 16 Val

Good morning, the engine failure is as follows, every time I turn on the engine it gives a sound as if it were a diesel engine and the 8 secure is removed after being on. The engine was new in December (all) 2011. The oil is complete uses semi-synthetic castrol 15W-40.

Year of the 1998 vehicle

What will that sound? Please

greetings

that have a good day

Three little things changed all shells in the crankshaft, taquets and oil pump

Oil as a minimum should be a 10W40 not a 15W40 The oil filter we are sure that it is sometimes you can go but it is not yours and the pressure deviation valve takes longer to act, in addition the sound is as if it were without oil or as if it were too advanced, there are so many things that can be

Good morning friend I made the engine I bought all your pieces in its entirety. With respect to the oil, I did not know that it could be placed 10W-40, the time is full advanced.
I will take your recommendation into account to see how it goes.

Thank you very much

that I have a good day
