So we just bought a 2003 Nissan Pathfinder. Its an LE and the exterior is immaculate shape for a 20 year old car. The interior is definitely showing its age but its the first car that I remember in our family with so many bells and whistles most of which work
I have looked around on this forum and the NPORA forum and took note of the dreaded powervalve screw problem. The car had 196,000km but runs flawlessly but I was concerned that maybe the engined ingested some screws. So I took apart the manifolds and thankfully all the screws and valves where there. However there are also the swirl valves in the lower intake (all screws and valves also present) and I saw that it was mentioned that these should be locktited as well.
Has there ever been any record of the swirl valve screws backing out? Is this an issue like with the power valves? Or is lock-titing them more of a peace-of-mind thing?
