Doesn't this sensor have a partner on the front of the other side of the engine, if you're talking about an actual VVEL sensor? Or are you talking about the MAP sensor that plugs into the top driver-side rear of the upper intake manifold?

Now i-Vtec adds the VVEL to the mix with variable valve timing to the intake and exhuast for better performance through the RPM band.

This engine only uses a regular camshaft on the exhaust valves.

i took that sensor out that is connected to the vvel motor that goes in the top back side of the im.it was oily.not dripping, but oily.so when you clean the maf sensors,hit that one too.

i also found this interesting;

It's tempting to go ahead and run dual cans with his stage 3 setup for the NA 370Z, and I might get around to that someday. You could use the existing fresh air paths since we already have two of them, just replace those plastic baffled things with regular hose through cans, and then cap off the PCV valves and corresponding manifold connections.

Interesting reading guys.

Which aftermarket oil catch can do you recommend, and is there a DYI out there? The link above is good.

Is cleaning the MAF sensors also on the list of things to do to keep the car running healthy?

Found it thanks wstar

DIY - Oil Catch Can (w/ M370 + Batt Reloc)

Well the M370 changes the hose routing, since you need to use a T-adapter even without a can for the M370. The same basic principles apply to the stock manifold, but if you want to do the stock one as a single-can setup you'd want to cap off one of the manifold inlets.

not sure if anyone's tried this in here, but i filled up with 10 gallons 91 octane. 5 gallons 100 octane (effectively making for about 95 octane) today just to see if it'd help with the hesitation in low RPM's. didnt do much. although i feel that it did make the car more responsive at highway speeds.

no hesitation for me and the car didnt lose any power.uprev fan mod is a must and i will be getting that sometime in the near future.for now,my temp fan mod stays and when i get ready to do some very spirited runs after car is fully warmed up,ill hit the switch and im good.

highest i seen my oil temp after this mod tonight was 210 where it should have been 225-230 with how hard i ran the car.it was 65 degrees out but the fan mod is still needed .25 row oil cooler before next summer and this hesitation should be completely gone for me.nissan surely made a big mistake programming the fans to come on when they do.thats 75% of the problem imo

interesting. i have a 25 row oil cooler and my oil temps never saw above 200 degrees after a 2hour run in 100 degree ambient temps. however..i definitely got the dreaded gas pedal delay when between 1-3k RPM.

any chance you can show us how you did the fan mod? i'd LOVE to do it on mine

you will need;

one fuse holder with 12 awg wire and fuse
around 24ft of 12 awg wire
one 50a toggle switch(2 prong,not 3)

i will mount the switch tomorrow in one of the blanks by the cup holder.i had it laying in the seat tonight testing to see how it worked before mounting it.hope you have some patience cause you're going to need it.make sure to keep the switch off when you are running the ac.

Pics if possible.

I've actually noticed twice on my 7AT there was a good 3 second delay after a U turn before the car accelerated hard

This transmission has taken a ton of getting use to after two CVT on the AUDI and HYUNDAI

wstar · 09-05-2012, 12:05 AM

Were you in manual mode before the U-turn, and in the right gear? Was VDC on maybe? My transmission never has a 3 second delay, that's huge. 3 seconds is like, time to eat a burger while you're waiting or something.
