hey all... ive been putting off doing this since i got the 260, i need to fix a leek problem i have sumwhere around the rear turbo... im hoping its the turbo to dump gasket... just dont wona have to pull HEAPS of stuff out.... is there any way to ultimatly locate the drama b4 pulling it apart... i know its to do with the rear turbo, its that usual thudding/puffing sound.

i got my 100k done at a reputable workshop here in adelaide. and they said its the turbo to manifold gasket... how would they tell by looking?? or is this a yeah he wont know its just the dump.... 1 hrs work $900 thanx for coming?? ill pull the heat sheilds off thursday and go from there

im guesing if it is that turbo-manifold gasket i just need a 33 gtr one?? and ill need to do both at the same time yes?

thanx :P

get yourself a short length of garden hose and hold one end to your ear while the car is running. move the other end around the area you 'suspect' the leak to be and you'll be able to hear it clearly ;)

i remember your car sounding a little tractor like off boost, what's it sound like on boost? any loud banshee-like squealing?

do you have a boost guage fitted? if you do, what happens to the reading when you're on boost etc

just realised you're on msn... will continue there :P

I spoke with a couple of friends at AJD regarding your exhaust leak issue, and the new wasn't good!

From a labour perspective, it seems that getting to the rear turbo means pretty much removing the front one.

However, removing the intake & shielding should help reveal the source of the leak - they will squeal like crazy on the intake side of the turbine, from memory your car sounded more like a head/manifold leak (i.e. a tractor)

Keep us posted Adam...

Mine went that way. I bought another turbo but when I pulled it down it was broken manifold studs. Bugger of a job but got studs out without taking head off.

If you do find broken studs, a fairly common RB issue, look in local Yellow Pages under nut/bolt suppliers and ask if they know of a mobile stud fixer. I was lucky one lives here on Tamborine and it was $100 to get four removed.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      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.
