is this bad???

[motoking_1990]

went and picked up a stock turbo yesterday for 50 bucks and there is absolutly no shaft play what so ever radial or end play but when i left the place where i met the guy * from craigslist* i noticed there was oil residue in the hole after the compressor wheel where it goes down and ties into the intercooler does this mean there is something wrong with it? the guy told me it worked perfectly fine when he took it off and it only has 120k on it. the reason he took it off is because he put bigger one on his and he gave me such a good deal on it cause i drove 5 hours to him. i can post pictures if need be!

What kind of turbo? An IHI or a VVT. Oil if it was a vvt could be from the PCV on an lly or later.
Does the turbo spin ok?

 

[motoking_1990]

it is an ihi and it spins freely and its smooth but you cant just spin it by hand and it keep spinning.

The guy could of had a oil type air filter.

there will always be a little oil residue due to the way the oiling works on a turbo, especially if they ever had a intercooler boot pop off at one point or another.

Ok I am not that worried anymore thanks but now I got to thinking how much metal got in the oil when the turbo went out

Got the new one in now I have to tie up a few loose ends intake bolt the glow plug box back in and a few other things. Pulled the intercooler line off and about a gallon of oil poured out any one know how to flush the intercooler? Don't wanna use water really

Calgon automatic dish detergent and hot water is what I would try. It's what I use to clean cooling systems that contaminated with oil. It doesn't foam up much if at all. Mix it up in a 5 gal pail and pour it in the top of the IC with the bottom plugged. Shake the IC up for a bit and then rinse with hot water till it's clean. Then take your ol'lady's blow dryer when she isn't looking set it to hot and stick it in the top hole and let it run until you don't get any more water coming out. Or a shop vac set to blow would work too.
This should take out the oil along with most of the metal that may have made it's way in there. Tough to get it right shiney but it's better than what it looks like now.

Other's may have different methods, like taking it to a rad cleaning shop and letting them deal with it, but that's how I would do it. Good time to check for holes in it too seeing as recently alot of people with LB7 and LLY trucks have been finding holes around the inlet outlet support brackets.

I would use clean diesel in the IC to clean it. After that then use some type of cleaner to get rid of the diesel fuel.

Get as much water out as you can like mentioned. Do not know if I would use a hair dryer or shop vac to try and get the water out. Stand it on its end with one of the tanks down in the sun and let mother nature work for a while. After that, hook it up and let the hot air from the turbo do the work.
