hey guys went to see a couple of supras today, dont worry im a gtr fan but p plates restrict me from buying one. Anyway the car i was looking at the exhaust was blowing white smoke i gave it time to warm up and was still blowing white smoke when pushing the accelerator down? what can be the cause of this im guessing clearly its not a good sign? also when looking for imports what are some good indications of how the car has been treated if the kms are legit? etc.. ? thanks guys any help will be appreciated.

white smoke? indicates piston rings are worn... not a good sign

good way to see is get him to start it cold, say when u want to see it dont run it before u get to his house, so u can see what its like to start

see how long it takes to start the car with the key, if it turns over for ages to start its not a good sign, a quick ignition is a good sign

when the car is running when warm, open the oil filler cap and see if any blowby is coming out, maybe get ur mate to rev the engine a bit to see the blowby, blowby is bad

check the chassie for cracks and suss repairs

check the sump for bog (if people stack over a gutter, they might bog the sump up to hide damage, ive inspected a car with this done to it)

the kms are never legit, that's part of import life im afraid. i read somewhere ages ago, before i bought my gtt, that the cars are often wound back 60000km, not sure how they knew that though...

hey clutch, will the blow by just look like sooty crap coming out?

There are so many things to come in to play when buying a car.

You should really get hold of a workshop manual for the car and read towards the bottom of the manual. It will come up with common problems on the car and the symtoms and fixes for all these electrical and mechanical problems. These are a guide line too helping you with getting a car thats running well.

Its the best way because you will forget to check somthing while you are there, guaranteed!

My R34 blows white smoke and its because im missing a certain part in my Catconverter :blink: , at least i know its something i did thats causing that to occur and its not harming my car only the enviroment and anybody who want to hang around the back of it while its on. I suggest you leave that supra where it is at the dealer, my mates a mechanic so i had him check out my car before buying. Strongly suggest you do the same.

on supras the main cause is valve steem seals, not really piston rings. two of my mates own turbo supra pushing out bulk power and they both blow white smoke due to valve steem seals. Changing the oil will stop it for about 2,500km and then it will start again.

do a compression test on each cylinder. gives you an accurate reading of warn piston rings.

when u open your filler cap IF THERE IS blowby then it will just be smoke, not soot

    • I'm going to slap an old nismo logo sticker on my spare one and sell it to the land of the free for a thousand bucks
    • lol, probably should have read further!
    • Well - they have arrived.  And they are easy on the eye to put it mildly... These only have three bolts - but for a start there is a key that fits with vacuum like precision..  And as you can see by my ruler, the interface is large..   I listened to a podcast on HP Academy about Dan (KiwiCNC) and I'm more than comfortable he knows what he is doing. R35 Bearing assembly should arrive later today so can mock that up for a look. Can't wait to get these on and get some brake pressure logging too. IMG_3860.MP4
    • I would be very confident that they are the same parts (the 2 different SKUs). It seems very clear that you can drop the cam in the 2-way opening, or in the other opening. If you arrange it in the other opening in the same way that you see any other 1-way diff, ie, with the flat of the cam up against the 1° side of the opening, then it would work as a 1-way. It can only spread the ramps when driving forwards - cannot spread the ramps on overrun. It would then appear obvious that if you put the cam into the opening "backwards", that you would get the angled flats of the cam working onto the "points" of the 1° side of the opening, which would give you ramp spread in both loading directions. I do wonder if the forward direction of the 1.5-way config is equivalent to the forward direction of the 2-way, seeing as the cams are flipped and the angled surfaces on those would need to be the same on each side - AND - clearly when installed in either the 2-way or 1-1ay configuration they are not intended to work exactly the same (the ramp angles on the 2-way are 10° different between forward and backward, and the ramp doesn't exist in the 1-way config). 'twere me, I think I would rather actually have a set of rings that offered the 2-way with two different sets of ramp angles, say the 55/45 of the existing design and maybe a 45/37.5 combo for a less aggressive effect), AND another set of rings with a dedicated 1.5-way opening and a dedicated 1-way opening. The 1.5-way opening would actually have the steeper angle on the overdrive side that causes it to be less pushy than the forward drive angle, like you see in many other diffs. But really - if this Nismo thing is thought out properly and all those surfaces work on each other the way that they need to, who am I to argue?
