finally got all my engine back together today after the big rebuild (rb26dett). didnt think anything of it when the turbos (2860-5's) had been sitting it had oil leaking out of them and we just assumed it was because they had been sitting for so long. but when we took it for a drive today just blew a shit load of smoke. and now they are both leaking oil. not happy

what do you mean leaking oil? ...when mounting these turbos did you use a oil restrictor? if not, try to fit a 1 - 0.8 mm restrictor to the oil feed. The smoke may go away. That is unless if you are shure that the seals is not gone.

If oil's coming out of the inlet side with out any obvious shaft play then it means you've got an oil drain related issue. Check the drain pipes make sure its not kinked, bend or capable of storing oil.

Also remove and check the drain adaptor if you or your mechanic sealed it up with silicon instead of gasket.

when we pulled the turbos of the car the were fine and hadnt been leaking oil. They have been sitting in a sealed box for about two months why the motor was bein built. and yeah when we put them back on they have devoleped a leak. but also when we pulled them out of the box the had been sitting in there was oil everywhere in there so would i be correct in saying and hoping that just new seals and no major expense

considering you can see it droppin from the turbos and the whole rest of the engine is dry. yes i am very sure it is comin from the turbos

did you replace all the copper washers?

its ifs dripping/dropping from the turbo i would say you have a leak in one of the fitting going to the turbo and that the turbo themselves may be fine

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
