Hey my gearbox is crunching every now and then, when shifting up to 3rd or 4th (sometimes when driving hard; other times when crusing) ... i am thinkin maybe my syncros are going?

I plan on changing the gearbox oil this weekend and seeing how that goes.. however if this doesnt cure my problem, what am I looking at for a repair cost??

sncryo's + labour?

rebuild of the gearbox?

new gearbox?

just so i can see what the best option i can take is..

tnhx

Do yourself a cheap quick and easy favour and buy some "Redline Shockproof Lightweight Gear Oil". Put that in, give it a solid 500-700km of driving and then count the dolars you saved on that rebuild.

www.uas.com.au sell/deliver the oil. Call john and mention this to him and I doubt you'll get off the phone in under 10mins :cheers:

I never used to have any crunches but since my car got a high idle (upto1900rpm) i find it hard to change from first to second without sum difficulty and a bit of a clunking feeling thru the gear shift. It only happens up gears really and mostly between 1st and 2nd..Sumtimes 2nd to 3rd. Would the high idle cause this in anyway? If not would the shockproof fix it?

Thanks,

Deren

well i picked up some redline shockprrof on friday... got under the car today and tried to undo the top plug, with no luck... i huff n i puffed to no avail.

There seems to be some kind of silicone compound sealing the top bolt in. Can anyone let me know how to loosen this up? or do i have to hire a body builder for 5 minutes?

If worst comes to worst how much will a workshop charge me to hoist it up and do the change for me (noting that i will supply them the parts)

Everyone at UAS said the shockproof will fix it.

Mine still crunches in high revs post shockproof, what really helped however was them also bolting in my clutch slave in properly :cheers:

If your syncros are buggered I doubt oil will fix it, if you haven't changed oils for a while then you have a good chance any oil change will help it :)

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?
