No boost, lean, and smoke

[ohlegend]

I think I know what is going on with the car but I would like some more inputs.
I just got everything put back in the car, and tuned idle to around 14.7
When I start the car cold, I get some smoke coming from the exhaust, It lasts for a minute or two, then stops.
I took it for the first drive yesterday: It would not build boost, it was very lean, and smoked on acceleration.
When I was driving there was a low howl instead of the regular turbo spool up.

I was thinking bad turbo seals - I bought a used E316G and bolted it up.
I will also be checking for a boost leak - though hg at idle is around 18.
Also possibly bad valve seals?

Got a video? Low howl sounds like the whine of death (turbo). How was the shaft play on the turbo?

 

[ohlegend]

I do not have a video. There was no in and out shaft play and very minimal side to side.

What about now? Have you done a boost leak test? If you have a jpipe that's a real common place for a boost leak. And what cooler smoke? Was it smoking like this before the turbo swap?

I have to do a blt. The smoke has a blueish tint to it, defiantly oil. I had to rebuild the engine. I swapped to a 6bolt, and when I did I put the turbo on. Its a new build.

Ok today I did the BLT, and found a big leak at the inter cooler connecting and throttle body, small leaks from another IC pipe connection, injector seal @ #1, and the bov. I am in the process of fixing these, but the one that worries me the most is the leak at the bov. It is not leaking from around the mating surface, its leaking through the recirc tube. The bov is a newer (100 miles) NGR type s.

Edit: I fixed all of the leaks on the IC pipes and throttle body, and I will be doing the injector seals either Thurs or Fri

Ngr had a bad batch of BOVs that used the wrong o ring causing it to stay slighty open, thus, resulting in a leak during a blt. I had that problem, and they emailed me and explain what happen. If you go to home depot you can get a ten pack of o-rings for 3 dollars or so. Here is an email they sent me.

"Oh yes we had a defect in one batch with the o-rings, we just found out from another customer as well. It is an easy fix. The valve on the bottom does not seal due to the o-ring, which was incorrect size. The correct size is #18, we had a bad batch on those o-rings. You can either buy it at home depot and we will reimburse 10 dollars or you can ship it back to us and we can do it for you. Whatever is easier for you! We do apologize for that inconvenience! Let me know what you would like to do, thanks!"

Wow, you win a gold star for the day! Thanks for the info. Looks like I need to make a stop at home depot.

Did this stop the smoking?

I now have 0 boost leaks, I had to retune, due to having tuned it with so many boost leaks. I was dumping tons of fuel into the cylinders to keep up with the extra air I was getting from the leaks. The smoke could have been just gas. I am going to test drive this weekend and see how it goes.

Did it end up being a bad o-ring in the bov?

 

[ohlegend]

Yes, It was leaking horribly. Luckily, I had a spare type-s knock off from my Punishment racing FMIC kit. I swapped the O-rings and it sealed up nicely. Thanks for the advice!
