Hey guys. I just saw some updates to this posting so I thought I would reiterate what bowtied was asking to Morpheous: We know the power valve screws and what not were an issue, but what about the lower swirl valve screws, in the lower intake manifold? Are they of concern and should we do something about that? Or was it really just the upper power valves that were the issue? Thanks very much.

Hi there. I am a 2004 Pathfinder LE owner and have been reading different sites and postings about this power valve screw problem facing the VQ35 engines. I know that the power valve screws are the main culprit here BUT after reading BowTied's posting on how to do the job with the power valve screws, he mentioned about the swirl valve's in his intake manifold, which is just below the lower intake manifold collecter/power valves. Do we need to be concerned about these swirl valves located inside the intake minfold, and the possibility of THOSE screws falling out as well? Or do we only need to be concerned about the power valve screws? The reason I am asking because its alot more work to take the intake manifold out, and there are more gaskets to replace, but if the possibility of those screws are likely to fall out as well, I think we should be concerned about those too.. wouldn't you say? Read BowTied's posting on how he did his power valve screws, and scroll down to where he is talking about his swirl valves if you need to see what I am mentioning about. Any comments or thoughts about this would be very appreciated. Thanks very much. By the way... I have a Nissan FSM and I cant point out where it is exactly, if anyone needs me to. If anyone else need a picture of this, message me. Thanks.
