For some reason my '05 350z will get stuck in first gear when parked on a hill, this is only if the gearbox is holding it (if the handbrake is, its fine). 

I won't be able to pull it out of first gear, even if I push the clutch in with the car off and it won't roll back either even with the clutch in.

The only way to release it, is to turn the car on with the clutch in and then I can pull it out but it always makes a big thud. 

Is that normal, in my R33 I can push the clutch in even with the car off and load on the transmission and change it out of 1st.

I don't see that as a reasonable excuse for not engaging the handbrake, at all.

I hope you're at least turning your wheels in the right direction for your vehicle to veer into the kerb so that it doesn't roll off and damage someone else's vehicle or kill someone.

Pardon my judgmental attitude but part of motoring is thinking responsibly about everyone around you and your heavy steel weapon. We have parking brakes for a reason. They are the primary safety device, not your gearbox.

Let me say I almost never use the park brake on my autos, but that is a very different situation to manual. 

Auto has a pawl which locks the gearbox. Manual is just using engine compression to hold the car which is not safe depending on the slope or unexpected extra load like another car or a person leaning on it ;)

I think best practice is pull up to a stop with foot on the brake, pull up the hand brake, release foot off the brake pedal, turn off the car, clutch in (or not, don't think it matters once car is off) put the gearbox in 1st or reverse depending on whether you're facing up/down.

 

I do this in autos too, foot brake, hand brake, release foot brake, put lever into P.

I'm not so trusting of that idea either. I know of two people with two vehicles whose pawl did not hold their vehicle at all and made quite the amusing ticking sound as they rolled away from them. One caught his vehicle in time. The other, well, the write-off was a blessing in disguise anyway. To me, they're always a backup to the parking brake, not a primary.

Many cars do have neutral inhibit on manuals.  The Holden Cruze has such a crap handbrake they will roll away unless you crank it on hard and the owners manual specifies to leave in gear. Mate had one roll out his driveway across the road into neighbor's yard. Everyone was ok luckily , and from my perspective it was very funny.

It always is when it's not your car. :P

Which reminds me, I need to readjust the parking brake on my V36. Nobody has really been capable of giving it a proper adjustment, working on the cable instead of the shoes themselves. I always get a little nervous creep from it.

Squeezing the oil out of your engine bearings to hold the car on a hill sounds like a shit idea to me.

Hey @Ben C34 was this directed at my method?  Just would like to know how you mean as I am a mechanical numpty.

 

Cheers,

Not you directly mate. What you have described doesnt load up the gearbox and then engine unless the hand brake doesnt hold.

I never leave a manual parked in gear. Accidental key turning can result in panel damage because there is no neutral inhibit on a manual.

The handbrake is there for a reason.

Everyone here veered straight off what I was trying to ask, I wasn't after a safety lecture. I don't usually leave the car in 1st gear on a hill ffs. 

What I was trying to ask is, if I am on a hill and for whatever reason the gearbox is the reason its being held on the hill (lets say its in a controlled environment, in the middle of mexico, with bubble wrap all around it and cotton wool just in case) it won't let me pull it out of gear (even with the clutch pushed in of course) unless I start the car. 

That is on my V35 with a twin plate, solid center clutch. It's been in the car for over 20,000km and doesn't show any other signs of dragging the clutch. 

My R33, you can hold it on the hill in gear with the gearbox and if you push the clutch in even with the motor off it will let you pull it out of gear, the v35 doesn't do that. 

 

Is that a symptom of a twin plate clutch, or is there potentially something else wrong - like maybe clutch drag even though I highly doubt that being the issue.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
