R34 Gt Vct Solenoid

[RB25DETC33]

Hey guys, I'm having issue with my 34 still. I found out the vct solenoid is no longer working and leaking through the plug. Need to know if anyone can confirm a hot start problem with the vct not plugged in. I'm trying to source a solenoid but its proving difficult. fuel consumption is poo, car is hard to start once its warm, and has shocking performance.

Does anyone know if a failed vct would give a hot start prob.

No

VCT doesnt turn on at idle, and AFAIK your startup would not trigger it either.

It's hard to say if the poor performance has anything to do with the solenoid or if you have another problem that is causing all your issues

Does no vct cause poor economy cal ?

I don't believe it would screw up your fuel economy. I'm not sure if vct is active at cruise off the top of my head but don't think it would hurt your economy to much if it was on

Someone smarter then me might know more. But off the top of my head i don't think so

I thought vct advanced the timing through certain rev ranges to let more air into the cylinders? Not sure on this but i think i read somewhere it did. So if its not working then it would burn more fuel wouldnt it?

Vct advances inlet cam between 1500 - 4900 roughly

Advanced Timing doesn't "let more air in" it changes the point in the cycle when the spark plugs fire to burn fuel
