Hey all, I recently purchased a s14a with 82k miles on it and its got the vvt rattle, or at least i think so. After i did some searching and reading on here im not too sure if it is a vvt rattle now and am hoping to get some expert opinions on whether or not it is!
Symptoms:
Cold Start - Slight rattle every now and again but most cold starts it won't make any noise.
When Warmed - Loud rattle can occur when sitting idle for a minute or so.
Warm Start - Very loud rattle which persists even after pulling away for a bit and returns when sat idle for 20 seconds or so (at a long traffic light or something).
After a warm start i tried the "put in gear and rev to 1100 rpm or higher" and the loud rattle persisted through the rev range.
Unfortunately this car came with absolutely no service history so am unsure if any of the things that needed changing around 60k-80k have been done and if this would affect the diagnosis.
Any help would be appreciated!
Edit: (Extra info) Warm Engine: In gear and rev to 1100 rpm - seems to quieten but still present above 1100 rpm, revved to about 3-4k rpm and then it goes away when in gear and at idle revs. Otherwise if i just rev to 1100 rpm and then let the revs drop to idle the rattle remains consistent.
