used t25 smoking

[icnuthin]

hi peeps.i just got finished today swapping my t25 with a friends t25 cause as i boost to 7psi, right as it hits 4psi it would make a bad fluttering sound, and wasnt running as strong anymore. when i pulled it off the shaft was wiggling around.

now his t25 was sitting up for 9-10 months. his motor blew back then. but as it idles it smokes very little and when i rev it to 3000rpm a big puff of white smelly smoke comes out. he said when he got it he needed a oil line pressure reducer and when he put it on after 4 days it stopped smoking all together. it has that same reducer and now its smoking with or without it. but less with it

the trip part is that the turbo is kicking strong spooling at 2200 rpm and the 7psi is back strong in the car. just this damn smoke problem. im going to run it up and down my street for a few days boosting so that maybe it will stop.

anybody else experienced this. sorry for the novel

Could it be pooled oil? Or maybe bad seal?

also the coolant lines i took off and plugged them with 2 oil bolts. should i have left it open.

[Zippy69]

Well you have an oil feed and return and coolant in and out. I think a lot of folks leave the coolant lines off as some think they aren't necessary, I figure if they put coolant hook ups on there, then I should use them. But I know that they shouldn't be intertwined any where. Did it ease up after you drove it for a bit?

Your turbo could use a rebuild, if its not smoking bad then you could just run it.

[icnuthin]

no its bad. i tried running it again today and after 30 sec of just idling it started to smoke and when i gave it a little gas bump it was bad.

a friend is selling me a hks t25 for 75. and it doesnt smoke. works perfect.but thanks now i have 2 t25 that needs to be rebuilt

ok heres a little update.

that t25 BUSTED. i had oil in my intake lines.

new well used garrett t25 with hks internals. BLOWS MY MINDthat thing is a beast.

quick question how should i go about cleaning all that oil that went in my piping.should i just open after the turbo and start spraying carb cleaner. only cause at first it was bogging down and i got scarred to drive it and after idle for 15 min i drove again and blew some smoke out then it started driving like a beast.

exe. it use to break the tires when i was WOT hitting 4k rpm in first it does it in second too and i get thrown in my r32 seat even more.butt dyno is very happy

does it still puff a big cloud of white smoke when you give it gas? You know your turbo seal may be bad and it might be throwin oil in your intake piping, you should look into getting a new seal if that's the case.

[icnuthin]

no i ran all of the oil out of my intake. changed oil and new plugs and the turbo is kicking so much ***. i love the **** out of it.

is the seals easy to change in the turbo with out having to get the shaft balanced
