OPININ NEED IT!! URGENTLY

[vettekiller]

hello mates,

i have gtr r33 stock turbos, i push 1.2bar to the stock turbos, i need to know if my tubos are going bad.

well, first of all i check the engine, i check the plugs are fine, no oil in it, have very nice orange color. i check the intercooler piping have a little oil but normal because my rb have all the head breather to the turbos like stock.

i remove the the breather hose from the head, no smoke coming out!!.
and last i make a leak down test , and they are 1- 20% 2-20% 3-15% 4- 15% 5-15% 6- 15% so, the engine is ok.

my car idle good, but if rev the car let say to 5000rpm standing stll a little smoke coming out, but once it get to idle smoke more clearly.
i i rev the car to 3000rpm and stay there for 30 second no smoke comming out, just when it get to idle, alittle somke comes out.

just in case i change the oil valve seals. but the thing is that if i drive the car on the street normally on the lag section, everything it is ok, but let say if say rev the car hard pull no smoke comming out, but when stop inmediatly the car come back to idle a little oil smoke comes out.

let say i rev the car standing 4000rpm and cut ,very little smoke comes out but if i rev the hard to 7000rpm standing very little come out, but the problem when get to idle, white smoke come out, but it is very little, because it doesn't show anywhre, i check the plugs, i pull out the downpipes to see if one of the turbo is darker, but no they are orange color nice color both are the same.

i start to pull apart the turbos , i start with the back turbo, well, seems very good to me , very little play up and down, normally for a turbo. and no front and back movement.
and the front turbo, i notice that my maf is dirty like oil gas, well to me is normal to see that, but when i get to the front turbo, i notice that have little play up and down, but when i check the movement front i back i notice big movement like 2mm in and out, COULD THIS BE THE PROBLEM THAT THIS MOVEMENT CAN DROP A LITTLE OIL?? AND BURN INSIDE TAILPIPE?


please help urgent , i need to know what to check, or in deed i need to buy new turbos.

Sounds like you have found the problem.
There should be no in/ out play at all on the turbo.
