I blew the turbo pretty bad, the whole turbine was chewed up:evil:......I took the intercooler off & metal filings/shavings were in there with alot of oil......should I be looking for a new motor soon because of all that crap is in the pistons, cylinder walls, can I some how flush it out? What my best option?

TIA

Hmm that's not good.  If it were me I would change the oil immediately.  Then let the engine idle for a while and change it again.  And again, until I don't see metal in the old oil.  Don't know if that would help at all, worth a try I guess.

If you can find a big speaker magnet...........put it on the oil pan below the pump pick up......


and do like no1kicker says with oil changes at idle....

I will do that but I'm worried that all the shavings went into the cylinder walls, & will scrape up the sides & will Eventually kill the motor due to loss of oil pressure, I think I can get a motor for $500.  what to do??? I'll try that & hopefully everything will turn out good

Thanx again

This past week when I took my engine to the machine shop we discussed the lost cam lobe on my car.  The machinist told me he has lost a lobe or had a damaged cam, which he simply replaced and changed the oil a few times and everything was ok.  I don't know what kind of metal the turbo housing is made of, but I wouldn't worry too much about it until you get that turbo repaired.  

I could have gotten away with dropping the pan and cleaning it and then changing the oil a few times, but I had the engine out so I am replacing all the bearings anyway.  You might be lucky.

It doesn't run anymore.

Nasty...how long did the motor run after the turbo went south? How much of the compressor wheel is missing?  8)

probably 1/2 an hr - 45 mins...........I'll be replacing the motor, you live & learn!

*edit* Sorry for the long post...got a few of beers in me!! :drinking:

Well...I can not see your motor...but I would not necessarily say you need to replace the motor. Depending on how much of the compressor wheel is missing would determine for me if you caused minimal or maximum damage. If you just nipped the edges of the fins you may have only sent enough metal into the intercooler to get collected by the build-up of oil in the intercooler (everyone has oil in their intercooler). The metal shavings are heavier than air (obviously) and my not have traveled all the way through the passages of the intercooler and back into the intake of the motor. I would look very closely at the throttle body butterfly valve and the surrounding areas to see if there is metal shavings up there. Look at the flex couplings that hold the upper intercooler pipe to the top of the intercooler and the throttle body. If you have signs of shavings there...I would do a compression test on each cylinder to see if you have any bleed off. If you don't and the shavings are not present...I would feel comfortable if it was my motor to thoroughly clean the piping and intercooler...put a new turbo (or rebuilt) on and have some more fun.

I had a Sunbird turbo that swallowed about 1/4" of each outer fin of the compressor wheel and slammed to a hault (the turbo that is). I was racing a 5.0L Mustang down I-25 at about 135+MPH with the stereo up loud. Had a slight miss type hesitation and a strange background noise. When I turned the volume down I heard a whiny noise from the turbo. Before I could back out of the throttle and shut it down I heard a hellacious screeching noise (kinda like when a 2 stroke motor seizes at 15,000 RPM! :shock: ) and a cloud of smoke behind me. No intercooler on that car so what came out of the compressor side went directly into the intake. I was so scared that I ingested all of that metal and caused serious valve damage and ring damage. We used a lighted flex scope to look inside of each cylinder and saw 0 damage or scaring on the walls. The intake and exhaust valve seats were untouched. Strapped a new turbo on and away she went for another 30,000 miles before I sold it... 8)
