You may also notice that you put the clutch fully down and you recieve a small notch of the gearbox when putting into gear/into another gear - this is because the clutch is not dissengaging properly because of the fault in the clutch hydraulic system (the master/slave cylinders)

Can you explain that a bit?

My clutch is sqeaking at the moment, and has for a couple of weeks. Sometimes first gear is hard to engage... Haven't had time to check if its internal or external, but I am guessing external.

Lucien.

Im currently in the process of making some beefed up clutch pedal boxes because the one in my r32 broke.

It managed to snap the two spot welds on the left side, put 2 cracks in the top (piece fell out after reomoving pedal box), and had a split in the top where it bolts up the top under the dash. This was after a year of using a 9 puk xtreme ceramic button clutch, and 6 months of an OS Giken twin.

Would there be any interest for some made up for r32 or r33? Just seeing as im making one, i may as well make a few....

will post pics of std r32 unit soon and then the beefed up version, made out of thicker steel etc....

Hi guys,

What does it mean if i have difficulty engaging 2nd gear.

This only happens when i reve the car in 1st gear very hard up till about 40-50km/h. I don't have this problem if I change to 2nd gear at about 20-25km/h.

I have no squeaks whatsoever and engaging every other gear is smooth.

Please help me out guys!!!

Right, my clutch is getting worse.  Damn squeeky.  Reverse is a bitch to get in to and so is second gear.  Are these symptoms indicative of the boost/master cylinder leaking?

Cheers,

Lucien.

Sounds more like a gearbox problem than the clutch if gears are hard to get into.

I don't think so. I think the clutch isn't engaging/disengaging properly. If I pump the clutch the shifts get easier, which to me suggests a seal is leaking.

Edit: Whoops.. "shifts" :)

Lucien.

if you can pump it up and it gets easier to engage gears then it's almost certainly an hydraulic problem like you suggested. get underneath the car and have a look at the slave (it's just bolted to the box) peel back the rubber boot and if there is fluid in there then it's leaking. a new slave is only like $70 or thereabouts so you should just buy a new one. very easy to change. if that doesn't fix it your master may be on the way too. unfortunately they cost more and are harder to replace.

Sorry, I got a phone call part way through the post so I didn't add all the details :)

The selection problem and the clutch noise seem to have arisen at about the same time. As the clutch has gotten louder the selection problem has gotten worse.

First gear can be tough to get in, but because the car is usually stationary, its not too bad. Entering second, however, is on the move and is proving more difficult. The problem is particularly evident if I haven't driven the car for awhile.

Richard: What about those seal replacement kits for the master cylinder? Worth a look?

Edit: few more things.

If the car is stationary and I go through the gears (clutch depressed) it feels fine. Likewise if the car is off, I can go through the box without any obvious problems.

Lucien.

ahhh, if car moves through the gears ok when stationary then it may not be hydraulics. they are worth replacing anyway though, and if they solve your problem that's a bonus.

if you are going to put new seals in your master you will need to have it checked as they don't always wear true. if it hasn't they can bore it out and install a steel sleve in there (which once assmebled with piston+seals will be better than a new stock one) only problem is a recconditioned master (bore, sleeve, piston, seals) costs about as much as a brand new one from nissan. it is better though.

as far as your problem goes it sounds like it *may* be gearbox related, BUT, I would certainly eliminate any clutch issues first (they are cheaper!). start with hydraulics (master, slave, line) then you will have to look at clutch (release bearing, pivot, pressure plate, friction plate), and if all those are ok it's gearbox time.

have you changed the gearbox oil since you got the car?

Gearbox oil was changed almost straight off the boat :) Its running Redline at the moment. Almost no shavings on the plug magnet.

My inclination is still that its hydraulic. I'll check out the slave cylinder as you suggested :) I have a replacement clutch line ready to install anyway, so that will eliminate another possibility.

Lucien.

yep when I got my car I replaced the slave. unfortunately it already had a nismo slave on there so whilst I got more positive clutch disengagement I did gain a MUCH heavier pedal feel (i have a twin plate OS Giken clutch), I also have a braided clutch line which I'm sure helps a little.

edit: what type of rediline oil are you using?

hahaha, yes I am burdend muchly.

Seriously though the twin plate clutch I have is a bit of a bitch. quite heavy pedal (used to be light with the nismo slave d'oh), very little communication (hard to judge 'take-up point), VERY BITEY, squels (un sprung, brass plates) and rattles when disengaged plus the box is quite tricky. MUST heal and toe down shifts, and when at a stand still always move it to second, then first.

However, when you are giving it some it alway works absolutely flawlessly. shifts oh so smoothly at 7000rpm++, does lovely smoking burnouts without clutch slips. launches at 6000rpm+ without slip or broken box. love it.

edit: I must say I have heard people advise against redline SP for GTR boxes. And I do know of one person who complained of gear selection problems after switching to it. I do believe it's what Redline reccomend though isn't it?

Took the car round to Grey Imports so they could have a look at the slave: sadly not a drip of oil. Nath played with the clutch and gearbox for a bit. Prognosis: expensive :rofl: The clutch is probably dead. I wouldn't be suprised if it has worn unevenly too given the way it sometimes dis/engages perfectly and others times refuses.

Now just to pick a clutch .. oh, and spread wide :P

    • This is lower price now given apparently nobody wants these or needs them. It's 550 but if someone sees it on SAU and wants to make an offer, please do so.
    • LS is a good motor, but it hurts my soul when I see it in a RB. Guess it fixes the oiling issues lol.
    • I'm confused. Does this qualify as "Gregging" or are you somehow avoiding the Gregging?
    • More assembly going on, with all sorts of "bolt right on bro" scenarios going on here. Smartly, PTV clearance was checked. And I say smartly because it turns out that the intake was 0.009" from piston meeting valve. This is 0.23mm. This is very not okay. A fast meeting was facilitated between engine builder in Australia and engine builder in the USA which was actually incredibly helpful and constructive actually, various ideas thrown around to get around this issue including: 1) Retard the cam timing which would have brought the exhaust valve closer to meeting piston (it was 0.065") which was uncomfortably close to begin with, and change the cam profile making it 'laggier' 2) Much larger head gaskets which would reduce compression, but half the point of this was to increase compression. 3) New set of pistons ($$$$$$$$$$$$$$$$$) 4) All of the above 5) Get ghetto The concept is you get sticky sandpaper and stick it back to a valve, slightly larger than the valve you/I'm using, like say from a LS3/rectangle port head. You now have a very super advanced flycutting tool to modify your pistons in your block. Then you install it in your head, and attach the other end of the head to a drill. Then you just replicate your valve smashing into a piston with your spinning drill.   This is the result. Repeat many times. It is strongly recommended you have some kind of fixed stop when doing this for extremely obvious reasons because if you press too hard then you're well into apocalyptic repercussion land. The minimum clearance on the intake valve is now 0.075" this is still in the "Too close to be really comfortable" and into "It should be fine" land. Supposedly in the real world the clearances will be slightly bigger. Guess this is what happens when people push envelopes for N/A engines instead of adding boost! Time to move onto the new, upgraded, higher ratio roller rockers from Yellaterra, all tapped and threaded with a stronger bolt for better stability. Very nice. Lets see how they fit. For f**ks sake. Time to bring the grinder out for these aftermarket, machined and CNC'd heads. Looks like the new, beefier rocker from YellaTerra has gone from Bolt on part to "Bolt on part". Well, lets see how this bolt on crank scraper and windage tray goes then, shall we? There actually is more clearance than they specify for this thing, but seeing it all move as you check it is terrifying when you see it all so very very very very nearly hit things. But after all, this is what the item is designed to do after all and actually did bolt on perfectly and have enough clearance to everything and some very clear and direct instructions. So +1 to Improved Racing I suppose. As above with the windage tray on. Photo of breaker bar wonkiness for added lols. Next up: Oil pump/front cover/water pump/sump and then it's time to actually install the heads, pushrods, head bolts, valve cover gaskets and such is all there and ready to go. (except the oil pump bolts which were previously longer for more clearance with the previously perfectly installed double row timing chain). There's definitely a sense that someone other than us has been here before and done everything perfectly, or at least considered it and came up with working solutions. Perhaps the previous cam was 6deg advanced to avoid PTV issues with the milled stock heads? In any case when I attempt to sell this stuff the buyers are going to be very directly informed.
    • my catch can is pretty easy to empty but it overflows due to the blowby/crank case pressure etc. max I have drained is ~600ml even with a ~2.3L capacity. So it is not just about having to drain it out its the mess it makes down the firewall and under the car and rear passenger tyre from the overflow oil being blasted by screamer + air in general. Ending up on the ground cleaning the oil up and having oil on your arms when everyone else can chill and watch the other sessions gets old fast
