It shouldn't be able to come backwards through the return...

 

Thats what I figured but its the only way my car can be blowing oil. Unless somehow I blew a metal headgasket thats brand new on arp studs:dunno:. I was gonna try another turbo on it to and see if my problems fixed but I dont wanna spend $40 on a turbo just to blow it again.

Also maybe the turbo drain is clogged? Maybe thats why I keep blowing my turbos?

 

Valve stem seals?

 

Blocked the oil feed huh? Good way to put a shit ton of metal in your motor.

 

The 13b blew an oil seal so I cut the oil supply completly off to the turbo because it was blowing oil through the exhaust.

It stopped burning oil and all was fine until I hit stutter box to see if the oil pressure would climb past 120 and it didn't but I had a lot of oil come thru my exhaust and can't figure out what it is from. It seems like turbo but the turbo feed is completly blocked off. Could it be coming backwards through the return?

I think Kurt hit this one on the head. Blocking the oil feed only made the turbo go kaboom. :blowingup:

Maybe you should rethink your strategy in life.

 

Yes i'm also confused why you decided it was a good idea to feed the turbo with zero oil.

 

I used to get mad a people like this that break DSMs but then I think of the part out or that its just making our cars more rare.

 

Running the turbo without oil is about as stupid as trying to fill your blinker fluid. That's why I hope what you've said wasn't stated clearly/correctly. I can't imagine you're working with a studder box but can't figure out that blocking oil to a running turbo is a bad idea.

If you did run the turbo without oil...well...you shouldn't go near a car...ever again.

 

No the turbo was already blown, the j pipe is off so its pretty much an N/A. The turbo doesn't spin at all and it is completly siezed. Even after all that happened I than blocked the oil feed to keep the oil from pouring out the turbo seals and it stopped. It now started spitting oil out and need to know where its coming from.

 

Okay, I am thinking either and oil ring or maybe a valve seal but how can I tell if it's a valve seal or a oil ring. If it was an oil ring wouldn't it do it all the time? Same goes for valve seal.

 

I would pull the head and see whats up if i were you. If you want your car to surrvive i would check the top end and def it is probably an valve seal. Get that car fixed and back on the road XD

 

You think maybe because I blocked off the turbo feed from the head it is making to much pressure in the head? I just put the head on it and it has a brand new metal headgasket I dont wanna mess up but if I have to I guess i'll have to lol.

 

The oil port on the head is blocked off from the factory, so no. You could be pushing oil up the drain tube if you have the vent hose on the valve cover blocked off and allowing the crankcase to get pressurized. Make sure that's not the case. Other than that, the head is really the only way for oil to get into the exhaust, assuming your piston rings aren't fried.

Did you deck the head and block before putting it together? Copper gasket sealer? Metal headgaskets have issues sealing if they're not against machined surfaces. What you'll most likely wind up having to do is pull the head, and replace the valve stem seals and redoing the headgasket.

 

Head was machined, block was fine and used the copper spray. This is a 6 bolt block and 13b. I have the PCV valve hollowed out. It could be the drain tube huh? Ill see what I can do to figure this out. Have to get car towed to my girlfriends house so it will be a while before I figure it out. Might wait over winter and ill buy a mighty max.

 

If you have the oil line to the turbo blocked off then the oil is not coming from the turbo pull the manifold see if the inside of the manifold and exhaust runners are covered in oil
(I bet they are) and if I am right you have bad vavle seals I have seen this happed on a few cars. I worked on a turbo b16a had the same problem and I agree with K Mans Tsi if that turbo turns at all it will drop metal shavings into the oil pan from the return line

 

True, but she will never turn again lol. Well i'll check inside the exhaust runners and see which valve seal is bad. Thanks

 

Well heres an update checked inside the exhaust runners and in the head and there is no sign of oil coming from the engine, only a dab of it at the collecter but the turbo is COVERED in oil, soo.... this must mean that it is coming back up through the oil drain correct? If it is could this be a reason why im blowing my turbos? It has to be coming through the turbo still some how. I am gonna try a known good turbo and see if it last's and see if it doesn't blow any oil. If you have any feed back please let me know thanks.

 

Have you done a compression/leak down test yet?

What are you feeding the turbo with? Stock lines? Modified brake lines? Stainless? -3an, -4an, -10an?

Even if the turbo is seized...it shouldn't be on there, oil feed or not. I wonder what kind of restriction a seized turbo makes in the exhaust stream? Almost a banana in the tail pipe, don't you think? Probly got mad torqz, tho! :chair:

But seriously, if you're so bent on keeping up the direction you're going, why not just remove the return line, plug the oil pan, and see what happens.

Buying a turbo for $40? That might be the start of your turbo blowing problems...you're probably buying junk. 13b? That doesn't exist as far as I have seen except incorrect websites and RX7s. 13g is more like it. Ugh, let's not run with that one in this thread though.

 

Oh yeah sorry 13g i meant, i dont care for the turbo so I could care less about its name lol. No the turbo im buying off a friend it is good and is on his car now. The 13b came off my FWD and was good and the 16g was bought new a year ago. Its being fed with brand new stock lines off the head. Compression is really good for a 160k mile motor. It is 160 across with a shaved head and metal head gasket. Im not driving it like this im just trying to figure it out before I put the 14b on it and blow it.

 

Ok, heres an update, changed the 13g to a 14b and noticed the hole compressor wheel missing off the 13g, it ended up being stuck in my muffler. That explains the oil problem. Started the car and it didn't go past 95 psi with the ported oil relief. I let it warm up for 15 minutes until the fan came on and than I hit stutter box, the turbo made a pretty nasty sound like the 2 turbos before did and I am worried I will blow this turbo too. Why am I blowing my turbos?

 

Blocking off your oil line to your turbo is a big no no.
You might as well drain the oil and run the engine.
Just don't block off the oil to the turbo and run the engine for a while.
The turbo will start to deteriate and end up inside your engine.

 

Obviously you didn't read the thread.
