Apparently upon bedding in a new mechanical diff you can either do figure 8's for 20 minutes

or

Have the diff specialist coat the disassembled plates with friction modifyer, then just drive off.

Still recommend changing oil after bed in.

What's the best way to go ?

Cheers

Do what the diff manufacturer suggests.

As above.

Some diffs, like my Tomei (which I think is a re-brand of the KAZZ) suggest 20min of figure eights putting in the clutch before you turn in for the 180 degree turn at the top and bottom of the figure "8"

kaaz reccomend figure 8's for 20 min's in first gear (clutch in before turn, clutch out after turn)

nismo actually recommend going for a drive in the hills lol...

i did the figure 8's for 30 mins just to be sure, then dumped the oil...

i had a mechanical diff put into a previous car i had, i never did any of this i just didnt do burnouts and i changed the oil after like 1000kms, and that diff worked fine.... what a waste of fuel doing figure eights lol... a good mountain drive fair enough.

$2000 diff...

$5 fuel...

somehow i think its a worthwhile expense

Certainly is.

Anyway, I'll be having Award do the install for me.

For anyone whose been to them...

Where the hell in Seven Hills can you do the break in without getting arrested ?

lol i was reading this and thought people were taking the piss. As conan asked where are you meant to do this bedding in unless you time your diff install with a skidpan day

It has nothing to do with skidding the car.

Figure 8's can be done in as little as 200m2 so go to a shopping centre carpark on a Sunday evening. It doesn't require much thought.

yeah ok.

But my intentions are:

Have award change the diff,

Hopefully return to their workshop around 3pm ,

do the break in somewhere,

return to them immediately to change the oil,

then go home.

I'm a fair way from Seven Hills.

:P

diffsonline.com recommend going no faster than 85 kph for 1200 miles !

That's going to be one boring drive.

Yep, I usually tell people no hard accelerating and nothing over 80km/h for the first 1000km to bed in the bearings, seals and tolerances. Then once in a while you get a VU SS ute come back after 200km missing half the teeth off the crown and stupid/honest enough to leave bald 20" tyres on the rear end :)

nismo actually recommend going for a drive in the hills lol...

LOL, that's asking for trouble. "90 degree drift along the mountain pass is desirable."

      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?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
