You know...

I was so excited to be done with the car, I started it up right way and totally forgot to crank it first.

I turned it off a few moments later though.

Man I hope I didn't mess anything up!

If it didnt run long its probably fine, maybe check it for shaft play.

Easier to just remove engine fuse and crank it.

Wow you didn't prime it? Looks like you'll be ordering a new turbo, or a turbo rebuild buddy. Check the turbo for shaft play by removing the intake and grabbing the compressor wheel and moving it around. From my personal experience i think your turbo might be done.

I certainly hope he has no shaft play. Hate to see all the hard work that he put into the car go to hell because he missed one step.

Best of luck man. Hopefully it all works out for you.

I removed the intake, and I turned the shaft.

now here is my question.

Possible degrees of freedom is: 1) radial shaft play (up and down) and 2 ) axial shaft play (back and forth / in and out).

I have absolutely no axial play,

but for radial play...

how much play is shaft play?

I put some pressure on the shaft up or down, and it is rigid.

But when I put a lot of pressure on it I do feel it move slightly but when I say slightly, I mean VERY little. more like just a "click". And that's when I put a lot of pressure on it.

Is there a way that I can tell for certain if the turbo is OK or broken?


I checked out some vids on utube about shaft play. I don't think mine has.

But when I got my turbo, I did spin the blades, and although I couldn't see anything touching the sides, I do/did hear a "scraping" sound.

It does spin freely (kind of) as you can clearly see when the speed is slowing down after you spin it, at a point where the speed is really slow it does stop by some sort of friction.

I figured its the bearings.

But I do hear a "sound" when it spins.

what do you guys think?


I spoke to MAP where I bought the turbo from.

He is confident all is fine and that the smoke will go away in about 100 miles. (depending how much oil was on the mani and if it soaked in good.

Also he said that all the turbos's they sell are under warrenty so if something did happen to just return it to MHI.

The only problem is.. how do I know for certain the turbo is fine. I don't want to take it out because some gaskets are RTV'ed in, and thats semi permanent. Don't want to undo those!

please ... any suggestions would be appreciated, I'm SO pissed off at myself for skipping the EASIEST step in the guid, and I now may have screwed it all up.

The turbo looks fine, feels smooth, and the "scraping" sound according to MAP is the bearings.

It sounds like it doesn't have any shaft play. But that still doesn't mean the turbo isn't f'd. I'd say prime it, and run it and see what happens. It's too late to go back now.

Drive the car around and see if it will hold boost, and if any thick black smoke comes out back during full boost.

ok first let me ask you something then I'll give you an update on my situation.

If black smoke comes out.. is that good or bad.

second...

My car has been sitting in my garage for over a year. Not being started not being used.

When I started my car and gave it a bit of gas a LOT of smoke came out. (my car is on stands). The smoke was white. I am almost 100% sure that is normal.


Now here is the update.

I called MAP, and told them about this (I'm SURE that scraping sound is not supposed to be there).

They told me they'd sent the manufacturers an email

They replied to MAP and MAP called me up.

Here is what they said. The turbo is under warrenty so I can sent it back and they'll fix it/ inspect it for free.

BUT.. they said...they CONSTANTLY receive turbo's from people thinking they have shaft play. They said that these 16G's HAVE shaft play. It is normal.

So I told them.. "when I push down hard enough on the shaft, the blades DO hit the sides".

They said thats normal too, and that during operation the blades won't hit anything.

So I inspected the walls.. and yup, no scratches no nothing.

So they told me its totally fine. SO I asked them.. "what if you are wrong, and I drive it, and I mess it up??... what then?"

THey said.. you have a year's warrenty, so they'll take it back and fix it if there IS a problem".

So it seems that either way I'm covered!

Now...

about the smoke.

Keep in mind that I put the manifold in a CNC milling machine and it got DRENCHED in coolant.. which is a oil based solution (oil and water mix).

I didn't rinse it off, I just whiped it dry.

The smoke SEEMS to be coming from the manifold, but you know.. its smoke.. it is hard to tell where exactly it is coming from especially that the drenched area's of the manifold is on the underside of the mani... so it's hard to tell if it is the turbo or the mani that smokes. But I am almost 100% sure its the mani, becuase the top part also eminates smoke.



So I'll do as 7 incher suggested.

I'll just prime it and let it run for a while (on stands) and see if the smoke slowely goes away.




now one question...

where the heck is the engine fuse??? been looking for it for more than an hour already.

thanks guys.

Hopefully I escaped near death.

Man you guys are EXTREMELY helpful!!!


ok now when you guys say "Priming" you guys just mean removing the fuse and crank the gas pedal for a while correct?

1. Remove fuse.

2. Turn ignition and hold the starter on for maybe 10 seconds. Stop. Wait a little while.

3. Repeat step 2.

4. Repeat step 2

5. Reconnect fuse

6. finished

Gotcha.

Thanks man.


The car still smokes but now it takes much longer for it to start smoking and the smoke is very little.

It really may just have been the oil on the mani.

Also

I only used 3 bolts to connect the O2 housing to the turbo. I was missing one bolt.
I didn't mention this before because I'm convinced it isn't the exhaust escaping as it doesn't smell like exhaust.


Sine I am under warrenty. I feel safe to just do what ever with it and if it blows I'll replace it.

no biggie.

I'll try to shoot a vid tomorrow, and put it on utube so you guys can see.

Seeing as you said theres remnants of that oil based solution you used then my advice is kind of useless. Now back to your other question yes SOME shaft play is normal, but if it sounds like its scraping against the comp housing then thats NOT normal (when the car is operating that is). I would just take the car out for a drive and see how it performs, and if you can build boost correctly and don't worry if its blown since they will replace it anyway.
