the oul vvt rattle has decided to start again in my car. its a 94 s14 drift car i bought from japan bout 18 months ago.. vvt hub started to rattle about 6 months ago -start off like bearly tappin and after a while got really load wit a grindin sound + even sounds twice as bad as usual the way it ticks over like a pig with the cams dat are in it.. anyway i changed it for another one that i was told was mint which was handy enuf do really.. when i had it done i was told to take the plug out from the cam angle sensor and turn on ignition to let the oil pump run oil to the hub. all was grand for a few months r maybe 4 r5 days on the track. rattlin mad again now. ive been told that this may be a sign of a weak oil pump even though the oil pressure is 100%..
shud i chance changin the vvt hub again n see how it goes???
was wonderin myself then d fact that ive a oil cooler and filter relocation kit would this be reducing the amount oil that can get up to that tiny pin hole on the vvt hub.???
note;; vvt hub or nvcs -nissan variable cam system, as sum people say...
help appreciated
