View Full Version : Bearing Material Found in my Turbo?

So my car started smoking when I was getting tuned with Jeremy. The car never smoked previous to the turbo install. So I think there may have been a possibilty that the seals were leaking on the turbo. So I sent the turbo back to where I purchased it from to have them look at it... he says the seals are fine, yet he has found bearing material from the rods or mains in the turbo... Can someone tell me how this might have gotten into the turbo? Is the oil filtered previous to the feed line? The kit came with a -4an feed line... could the line be too big? It seems most use -3an. The other odd part is, it starts to smoke after the pull.... like when the car dropped to idle. I have a vid for people I know, i don't want to post due to my plates being in the vid...
If you had debris in your oil pan, and the line to the turbo isn't filtered, anything can get sucked up into the cartridge.
What car? Did you turbo an N/A car? If so, who did the install?

That was my question, is the oil filtered where the oil presure sending unit is?
Eg with B18c now turbo'd with a Peakboost kit. Me and some friends did the install.
Ick. Sorry to hear, Pete. IM me if you need me to rebuild that turbo for you.
Where is the oil pressure sender - on the galley? On the oil filter housing? For future work, you may consider putting an inline oil filter in place between your oil feed boss & the turbo.
I did something similar to my supra - look here (http://jsalmi.com/buildup/oil/oillines.jpg). I had 2 feeds off the galley as the stock config was twin turbos, but used the inline fitler when I went big single. Just to be sure...
With that said, if there were bits of your internals found in the turbo cartridge, you've got bigger issues to worry about. Pull the oil pan and see what's going on in there.

I put a nitrous filter on my turbo oil feed. It's a wire basket strainer, flows well, and has a -4AN fitting on either end, so it's easy to hook up. It keeps the chunks out of my bearings.
And I second what John said, get your oil pan off and figure out WTF is up with your bearings.
John, how much is one of those filters? How hard are they to replace? How often did you replace them?

kinda new to this, how am i gonna know if my bearings are shot...

look for chunks in the pan, pull the rod caps and look at the bearings
Pete, I could probably help you this weekend if you'd like...

ill keep you posted matt, if anytime is to pull the pan its now. ... AGAIN.
Yep. Remember to pickup a new gasket.

The one i have is brand spanking new. And got hondabond too... :(
Matt - it was a cleanable filter, I think around $35. Plus the fittings & lines. I cleaned it every 5k miles - just to be sure.

I would like to get my hands on one of those.. where can i pick one up>?

:werd: I'd like to know as well.

How many miles? I reused mine with I think about 1500 on it.. but I thought you had a lot on it by now.

I just replaced it. Probably has 30 miles on it max. still leaking. This thing i swear on and on....
30 miles and it's leaking? Did you overtighten it and mushroom it?
I think any speed shop, something like On Track Performance, would have something similar. I ordered parts from some obsure tuner when I was putting the supra back together.
I believe the lines were -3 AN. Reusable Earls filter - look here (http://jsalmi.com/buildup/oil/oil03.jpg).

I dont think so. Might not even be the gasket. Return line maybe? valve cover gasket maybe... who knows I need to get down and find that shit. Driving me nuts.
I thought you told me your oil pressure gauge's sending unit was leaking??

Earl's fuel filter:

Be sure to specify that you want a screen-type element or you will get a 35 micron sintered bronze element.
Here's the filter that I used, it's a wire basket type nitrous filter, with a bit bigger mesh than the Earl's filtter (140 micron vs. 85 micron):

It looks like they are both -4AN.

Pete I am using a 4an on my setup but I have a restrictor on it like this
http://img3.freeimagehosting.net/uploads/6013f9abb5.jpg (http://www.freeimagehosting.net/)
My turbo went out completely about a week after my tune with Servion, I feel your pain with on & on my car has been sitting and Jeremy said since my new turbo is a little bigger I might need a retune so I am looking at almost 1k out the window. I loved the car while it was boosted but I have since had to replace a ton of shit just to kep it running right, makes me kinda wish I had left it alone.

The oil feed on a Honda is after the filter, there is a way for bearing material to get past the filter though. I find brass in VTEC sol screens all the time. When the engine is cold the filter will bypass pressure to allow for faster engine oiling. It most likely started to pass material through the motor during cold starts. Drain the oil into a clean pan Pete and look at it with a flashlight, if it looks like metal flake paint then you may have an issue. Pull the pan and look in the bottom for metal.

drained the oil and pulled the pan. It does have a metalic tint to it like paint would but there aren't any chunks what so ever. I pulled the pick up and that piece that covers the crank. Nothing in there either. Like I said, there is deff a metalic touch to the oil. . . could this have been caused from oil starvation?

yes it could have if you see any thing that looks metalic you should check the bearings.
just pull one cap and look at the bearings

Don't you have to torque those down? I don't Have a torque wrench...

I wouldn't mess with those if you don't have a torque wrench. And technically I believe you tighten rod bolts with a rod bolt stretch guage. At this point, given the metal flakes in the oil and your level of engine assembly experience, I'd advise taking it to a shop and paying somebody competent a few $ to pull the caps and check out the bearings. It's a pretty quick/easy job and shouldn't cost too much. If you're around Denver, Tobi would be a good pick for evaluating the condition of your bearings.

Thanks Roger, I will be having tobi look at my bearing here soon when I get my car back together. . . Ill keep you guys posted.

I have the N1 pulley and was told to take it off because it is not balanced and with a boosted bottom end the bearings and such will not last, a friend of mine with his boosted GSR teg spun a bearing he has a unorthadox underdrive pulley. Basicly I was wondering if the bearings on your car might have seen damage if you would have had a differnt pulley that's all.

Oh, I see. Its stock.
Thanks Chad but I think I am going to have Tobi look at it. I don't want to get to far over my head.

we just need to find out the issue with the oil pressure and I think you will be fine, the internals looked fine and there was no chunks of anything in there, but it is a good Idea to have tobi take a look at your bearing and see if they need to be replaced.
P.S.- could a blown head gasket cause the oil pressure to drop??
HONDA GHANDI
07-19-2006, 01:41 PM
No, not usually. There is little to no oil pressure on the head gasket. The only place a HG failure could cause a pressure drop is on the intake manifold side dead center. If it was bad there you would have been raining oil externally.

As discussed earlier, definitely check out the bottom end and fix the oil pressure issue... we're all hoping everything turns out OK for ya.
