I imagine that I try the coil the spark plugs The oxygen sensor sensor of crankshaft temperature sensor of the refrigerant liquid (very important) the TPS or butterfly position sensor, the ignition module that is normally next to the position of crankshaft, the Nissan now I do not remember it but it has a double tree of cams. if so it could be that they are not ready. When you check the draft you have in the view in the distribution the two gears of the cams respectively, it happens that as in other cars EJ Hyunday Elantra the person in charge of moving the second camshaft is the one that has the point with the distribution. That is, in addition to the distribution marks they agree on camshafts. Finally I recommend making the so -called Pichinga. It consists of emulting oil with benzine in 50/50 respectively and crossing the spark plug hole spray the shirts of the cylinders, it is achieved using a not very thick tube of APP 5mm colonated by the tip and with several holes at that same end, so as a syringe the emulciony is injected into all the dirrections, that will help me first. Ocacion that engine did not split and had excellent compression adjusted the cylinder head and everything, until I did the test and started a lot of smoke but is removed in the mother that burns the oil remains.
I hope this orientation is used in something.
