No, the noise stay the same. No noise at cold start, untill engine warm up. Have the noise only at idle goes away when rev up. And is loud
I am my self master tech at nissan and I know how to diag an noise but this is something specific to this tipe of engine and is first time working on. I inspect the roker arms and I d`ont see any damage. I also inspect valve lash in two diffrent ways: first I use a filler gauge and then I measure with dial indicator and all came OK. I adjust to.008 intake and .011 exhaust.
