Turbo install precautions

[tfoti]

Hey guys, need some advice here. I just bought another 14b turbo for my talon after my last one puked out on me after being on for about week. Heres the short version of that story: I put the turbo in, no shaft play. I replace the valve cover gasket and forgot to reconnect the vacuum line that runs from the intake manifold to the BOV. I rev the engine few times, turn it off and hear the clinking of the compressor nut as it shaves the wheels fins because the nut fell off. And it had in and out, up and down shaft play. The car was driven about 2 miles with that turbo on it before this happened (it isn't registered yet).

Anyways i am concerned about putting this new one on it because although the BOV wasn't connected for those few revs with the old turbo, would that have been enough for it to damage it so quickly? If you think NOT then what things should i go through to make sure this won't happen again. I KNOW that plenty of oil and coolant is getting to the trubo. Any insight to this would be appreciated. Let me know if there's any other info you need to know.

Thanks!

That could easily kill your turbo. All the back pressure bouncing off the TB plate and pushing the compressor wheel backward while the exhaust is still trying to push the turbo forward. Either that or something was in the center cartrige not allowing it to move very much but still be able to spin and when you fired it up it freed up and started wobbling like that but its doubtful.

Sounds like a combination of an already bad or going bad part and the no BOV thing. Either one of those things on thier own, the turbo would have lived for some length of time. But both together I can see it going bad that quickly.

Just take the usual precaustions. No shit in the oil lines, etc.

Thanks for the replies guys. I know the oil lines are good but am thinking about replacing them anyways with the stainless steel. The turbo that dies was bought off ebay . When i got it the first thing i did was check for shaft play. There was none that i could feel. And when i spun the wheel with my finger, it kept spinning after i let it go. So i figured that one would last quite awhile.

Shaft play and free movement say nothing about the potential for shaft nuts falling off

make sure the nuts are tight on the new one before you install it.

sorta off topic question. since im rebuilding my engine i know craps gonna be in the oil. im planning on changing it often but im wondering if a inline oil filter on the turbo feed line would be a good idea. i know usually you end up killing the turbo after a full rebuild and i dont want to trash this turbo since its got low miles and is ported and polished already. or would it be better to take off the turbo and bolt on a NT mani and downpipe till i break it in some?

If you already have a stainless feed line its quite easy to add a filter. Not cheap, but easy. I would recomend AGPs filter, since we know it works (saved my last turbo, only time I've broken in a motor and not lost the turbo). Its about 60 bucks IIRC, 4 an fittings on it. You'll also need a female-female AN swivel to make it work, they may have them, or you can get it from summit or similar. Any filter that is rated for oil flow, and filters down to 10-20 microns will work, but its hard to find filters that offer this info. There is a popular filter on DSMlink and perhaps the NABr forums, starts with a G, but I can't for the life of me remember the name of it... If it comes to me I'll post it here.

At any rate, highly recomended during motor break in...
