i lost my lower turbo on my little truck. it was brand new in the box when i put it on. it is a BHT3E made by borg warner pn# 172035 sn model G1004 485 . this turbo never builds any boost till 3k and i just find it hard to belive that i lost the oil seals on it so fast. i built this set of twins to have 0 boost at 65 mph and that is exactly what i got. so 99% of the time the big turbo is doing absolutly nothing. any idea what caused it to fail so early???
and i pulled a ht60 out of my shed and it looks to be a direct swap for my bht3e, but it has a good bit smaller inducer than my bht3e. so i am reluctant to use it. the ht60 is supposed to be a updated bht3e as i understand it but i am not 100% sure. any one know for sure and where to get the best price on a new turbo???????????

 

What size air filter are you running?

 

Does it have in and out shaft play? Or is it just blowing oil into the intake/burning oil?

Could be restriction in your oil drain line, or excessive crank case pressure.

 

it was blowing oil into the intake and exhaust sides of the turbo. i am running a bhaf on my truck

 

Did you tee the drain line into the stock/top turbo's drain? Most of the time not good. A good big truck junkyard would be good place to find a turbo for cheap and in good shape.

 

I'm thinking you have a restriction in your oil drain tube and/or too much crankcase pressure. Both will force oil past the turbo shaft, even on a brand new turbo.

For example I had this happen on my turbo eclipse, and it turned out the PO had clamped the valve cover vent tube shut by using a ricer type filter. Soon as I fixed that I wasn't mosqito fogging anymore. lol

 

it has it's own seperate drain, and i would only get the big blow by after i spun it to 4k or so. i may have to put in some more crank case breathers.

 

BHAF flows no where near enough air for what you are demanding.
You are pulling oil through the seals.

Ask Jim Fulmer about ruining turbos due to lack of air flow from the filter.

 

You need a better filter! The BHAF IS really a pretty lousy filter even for a stock truck let alone a twin powered truck. You need to get a good filter on there that can flow some cfm's.

thats how my eclipse was, would put out a bunch of smoke only after running up to higher rpms at WOT. Then when you let off the throttle it would start smoking.

And sounds like you need a better filter.

 

i would have thought that but i was blowing oil out my exhaust side also.

u might wanna try lookin at ur PM's to answer that question.. Hope u can find what ur lookin for..

I think an AFE is the way to go!

look here

$68.00
This is a AFE filter with a 5" inlet base of 6.5" top at 4.75" and height of 10" This filter works great with twins Part#0437

 

well i pulled the turbo apart and every thing checked out. i was going to rebuild it, but everthing looked new. i did find a kink in the drain line from the turbo to the pan. and it didn't seem to be that bad. but it must have been, i put the truck back together and all is well. i bent a piece of 3/4 " copper and slid it inside the drain hose so it can never colapse again. thanks for the ideas, i just wish i had found the drain line before i pulled everything apart.

 

If it wasnt collapsed all the way then it should still have worked. I never have understood why turbos only need a 1/16th in. hole for a feed line then they have massive drain lines. Thats the way all the race cars are.
