2004 Nissan Xterra XE 3.3L V6 AT 4WD
Good day! This problem has become worse over the last few months and I haven't been able to pinpoint exactly where it's coming from.
Situation: No codes thrown; No Engine light, but this issue typically occurs after the engine is warm and applying more throttle (assuming it's not a throttle issue).
The rattle gets worse and a very large drop in power is experienced as it sounds like something broke off and is rattling around inside somewhere, but subsides, or lessens in intensity after throttling back.
While parked, nothing... I can throttle the RPMs very high for a long iterations (within reason) and can not seem to replicate the noise.
The sound seems close to the top of the engine, on the driver's side, or possibly close to the firewall. The intensity comes and goes, but the issue is audible and power reducing, and obviously not correct.
Things I have done to this Xterra:
Hypothesis: I have also replaced the valve cover gaskets along with other associated gaskets involved in the replacement of. I do not believe anything foreign was introduced into the engine because of the precautions taken by placing paper towels into the valve cavities and alike. All were removed carefully, parts like the platinum were cleaned and vacuumed prior to installation of parts.
I think I might have read somewhere that it could be a bearing somewhere that is loose, I am just not sure where that would be coming from or what part that has a bearing that I could replace. Any assistance would be greatly appreciated.
