AWD going all the time is No good. Get it checked out, atleast make sure it has sufficient fluid in transfer case. Otherwise start saving for a transfer case rebuild, they are not designed for sustained use and it will wear the clutch plates out.

'Crunching in gear' like when you do a bad gearchange? if its happening during a normal gear change then it sounds like synchros are going/gone...

have you checked the gearbox oil, check if there any metal debris in it, if its clean then you may get away with some sort of teflon gearshift goo like Nulon etc, otherwise it sounds like gearbox rebuild time.

Cheers guys, I keep you updated on progress.

Dan :)

Ok guys,

My problem is solved! Here is what was wrong:

The front tyres were Dunlop 3000's - 17 inch. The rear were Kumho Ecsta's - also 17 inch. However. the Kumho's are slightly larger. Swapped the fronts to the rears and now works perfectly! Saved $400 for two new tyres!

I hope this is useful to others in the future!

Cheers,

Dan :(

ok. let me re phrase.

the torque guage will ocasionaly raise up while your cruising. then drop down.

it should shoot up if you put your foot down. pretty much any motion where the car jerks in a forward motion.

ps. i had front tyres new rear almost worn out. the torque guage was up the whole time till i put new tyres on the rear.

both were the same brand aswell. so it doesnt take much

ive got newer ones on the rear and gauge still read lil transfer to front while cruising on highway...when i had other rims with the semi slicks on the car...it was fine...but changing back to my daily rims..it will have a reading on it.. the tyres are the same size 255x40 but different brands, would this cause it as well?? Have the dirt garage torque controller and use the rwd option for the moment. Setting always on lowest except on wet days. Also tried bleeding the attessa...how long or how many times supposed to open the bleed nipple? prob about 20ml came out when i stopped doing it. any ideas? maybe have to change tyres from front to back as well

Your problem is going to be different brands of tyres, from my experience. HAve a quick vsual inspection from a distance. See if they look different. Otherwise, measure them up on flat ground. I measured from top of tyre to where is hits the ground, it was a little different. Even if its fairly minimal, that will be your prob. Try front to rear swap.

Cheers.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!

      Stock rb25det neo questions

      By GTSBoy · Posted

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Rb25det Belts Change

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
