Hello guys hopefully I can get answer after I really spend a lot of money for really nothing I know I am so late for that , after looong time researching I don’t know how all this time I didn’t see this thread!!!! Please note that my oil pressure is after fully warm up is around 8-10 psi / 2000k rpm around 40psi / cold start 80 psi now I have all above symptoms and I have confirmed that I did these 4 tries to confirm what all of you said These results confirmed by driving long distance with every try just to confirm the results 1 - disconnected both sides = issue gone 2 - disconnected right side only = issue gone 3 - disconnected left side = issue gone 4 - plugged both sides = got the issue back Really want to confirm before I waste more and more money I know the gallery gaskets needs to replaced but for now ,This sputtering will be fixed after I replace this vtc or the oil pressure will be the main issue? , I know and saw in groups some guys their oil pressure is less that 8 psi and they don’t have this sputtering if the replacement will fix , do I need to replace both sides full covers assembly or just the variable valve timing solenoid is there any possibility of any other warn parts effecting the vtc functions like bad pcv valve or others
