metal shavings ruined turbo

[dsmpower1]

hey , i had just had metal shavings running through my oil, ruin my turbo, now i have to have a whole new bearing and shaft installed. there goes a good 500 dollars. I'm just scared that it might happen again. i was using a 4 an feed line with out a restrictor. duh I'm stupid. so hopefully by using a oil restrictor/oil filter in my feed line it will help to stop that. I think all the shavings were in there because it was a fresh rebuild on head and block and it probably wasn't cleaned out good enough. Do you guys think that that would be enough to ruin a turbo? I mean i was on the dyno and after the 6th run tons of smoke started to poor out the exhaust. i went through like a whole tank of oil driving it home. oil not gas. i was planning on using the restictor/filter from forced performance.
also when i got home from the dyno , i popped the hood and i realized there was only 1 bolt holding on my turbo to manifold. im guessing this happened cause of vibration, i don't understand how that happened though, cause only turbo was messing up, not the engine, the engine was running fine. i just need to know if anybody might understand why this would happen, with the turbo being ruined?

Someone please help.

Add a magnetic oil drain bolt next time. It will help capture big enough metal debris that would otherwise get recirculated into your system.

did you do an oil change between the turbo failure and your first start up?

The most important question should be, "Where did the metal shavings come from?" My guess would probably be the engine bearings.

i was using a 4 an feed line with out a restrictor. duh I'm stupid.

Lot's of people use a #4 lin w/o a restrictor. There's nothing stupid about that. My turbo performs great w/o a restrictor with a #4 line.

so hopefully by using a oil restrictor/oil filter in my feed line it will help to stop that.

Yes, an inline filter is never a bad idea.

I think all the shavings were in there because it was a fresh rebuild on head and block and it probably wasn't cleaned out good enough. Do you guys think that that would be enough to ruin a turbo?

Most definitely. It doesnt take much debris at all to do some heavy permanant damage to the shaft and bearings on the turbo.

also when i got home from the dyno , i popped the hood and i realized there was only 1 bolt holding on my turbo to manifold. im guessing this happened cause of vibration

Vibration was not the cause of 3 missing manifold-to-turbo bolts. Those things are torqued down very tight (somewhere between 50-80 lbs if I remember correctly).

i don't understand how that happened though, cause only turbo was messing up, not the engine, the engine was running fine.

Debris in the oil will kill the turbo much quicker than the engine. But give it time; those metal shavings will eventually do a number on your engine too.

Debris in the oil is a very common turbo killer. Probably one of the most common aside from oil starvation. But if you are paying $500 for a basic rebuild, then you are getting hosed. A magnetic drain plug is also not a bad idea. I've been using one for the past 2 years and luckily, I've never picked anything up with it.

yeah i already have the magnetic drain plug and when i did the first oil change before the turbo failure, i had what it seemed liek a lot of tiny metal shavings. You see the turbo didn't go bad until i boosted it on the dyno. i broke it in for liek 750 miles before boosting it. at 750 i took it to dyno.

It's never a good idea to use a new turbo with a new motor rebuild. I would use an old turbo that you don't car about or a cheap 14B to break in the motor. Hell you can throw a Huch Magnet on the side of your oil pan and it will collect almost all of the metal shavings from your new rebuild. when you do your first oil change you just drop your pan can clean it out really good and you should be good to go after your first oil change.

On a side note those reusable oil filters like the K&N don't filter as well as the cheap paper filters such as a purolator or even the NAPA filters. So it's never wise to use those and never on a new motor. Lesson learned and sorry to hear your woows...
