I blew up my Holset AGAIN! Now I give up.

[95burgundyesi]

Well I previously fed my holset with a ss of the head, and it lasted about 5k. Smoked bad and picked up another one. Put a .078 restrictor and fed it from the OFH and lasted 2 weeks. At cold start up no smoke, but at idle after say 20 minutes I will get a single big white cloud or a faint mist of white from the exhaust. Coming off two step I get smoke now

WOT I notice no smoke and the car behind me(a friend) says nothing. My lines are not kinked and now the turbo is starting to loose spool speed. I am lost now. The only thing that I think about is the oil entry and exit is not 12 and 6 oclock by cocked at like 1 and 7 oclock, I was told this will not effect anything. I just don't know.

Also the stock head feed banjo bolt and the one from extremepsi are different in hole size, stock is at least double the size. Weird and maybe a factor when running from the head.

white smoke is not the turbo ! blue or light gray is oil ! could it have been light gray. and usually oil pressure problems will be at higher rpms, my mhi 20g is fed from the ofh and i get smoke from to much oil pressure !

 

[jrohner]

White smoke is coolant, not oil.

 

[dsm-onster]

As mentioned. . .Loosing spool speed because you're not getting enough to the turbo to spool it. It's going out the headgasket

Did you last one emit white smoke too?

 

[95GreenGSX]

Wow, you suck with Holsets, . Time for you to step into a new category.

Btw, doesn't sound like your turbo is blown. Maybe just a seal or coolant.

 

[95burgundyesi]

Last turbo had oil all in the exhasut housing and o2 housing and in the turbo, filled the whole garage with white smoke at idle after it went, put the second one on, no white smoke. So its head gasket eh? I guess This weekend I will check the gasket.

Friend said when it came out from the car with went frow dark gray to white by the time it was around the car.

 

[dsm-onster]

A blow head gasket will blow oil smoke out too. It seals oil galleys just like water galleys. . .

 

[95burgundyesi]

A blown head gasket will smoke at idle though right? like consistant? ide say 97% of the time I smell no oil or see smoke. I don't even want to check the turbo play, fearing the expected.

And I do not suck, I would be happy to drag your junk at byron at T&T.

 

[dsm-onster]

I've had blown headgaskeds leak at idle. And some only push coolant at WOT. White smoke is DEFINATELY not oil. But it seams some people are confused by what white is or blue. . . Not saying you are. But many have thought the color whas blue when it was white. OR the other way around. . .

Also I've had a blown headgasket pass a compression test. Same one that only pushed coolant during heavy throttle.

 

[dsmtalontsi95]

Is anyone else running this feed kit from extreme psi?

White smoke is DEFINATELY not oil. But it seams some people are confused by what white is or blue. . . Not saying you are. But many have thought the color whas blue when it was white. OR the other way around. . .

Blue smoke is generally an indication that oil has undergone the combustion process in the actual cylinders. White smoke can be an indication of oil IF it doesn't go through the full combustion process (through the motor) and is burned in the exhaust alone (aka the turbo misting oil into the hot hot exhaust).

A buddy of mine blew his 50-trim 2 years ago and it smoked a ton of white white smoke at idle AFTER a hard boost (25+psi 2-3 gear pulls). It also tended to emit a white smoke randomly once the car was warmed up and just cruising. The turbo was only oil fed for lubrication and cooling. Once it was rebuilt, the smoke went away and he continues to drive the car today.

The white smoke was from the turbo. This does happen.

white smoke is not the turbo ! blue or light gray is oil ! could it have been light gray. and usually oil pressure problems will be at higher rpms, my mhi 20g is fed from the ofh and i get smoke from to much oil pressure !

I also get WHITE/gray smoke from my 20g due to having way too much oil pressure I can smell that it is oil being chocked up in the turbo or going through the exhaust. I get that blown turbo smell every one in a while... I need to put a smaller restrictor in because when I cranked the car with the feed line from the OFH in a cup I got a full cup of oil within 2-3secs!!

Not true white smoke can be from oil..

 

[dsm-onster]

I stand corrected

 

[95burgundyesi]

If someone can tell me what a stock dsm gets for oil pressure that would be great. that includes balance shafts. Then I need to finish my wiring tonight for the pressure gauge and see how far off I am from stock oil pressure.

I still think that feeding from the head with stock like oil pressure might be better, And a big problem might be the smaller hole in the extreme psi bolt compaired tot he oem banjo bolt. I looked at the two and the both holes in the oem bolt were much bigger!

 

[dsm-onster]

You can't ask what the oil pressure is because I guarrantee you my motor will be VERY different from the next. This is why DSMs kill garret turbos, and improperly fed MHI turbos, and BW turbos, and Holset turbos, and anyhting that has any sort of minimum and maximum for oil pressure and flow.

You really need to get an oil pressure gauge on your feed (after lines and restrictors) to answer that question. DSMs: destroying turbos since 1989!

 

[95burgundyesi]

This shows the difference I noticed

 

[dylnwit]

To me it looks like your oem one is drilled/ported out some, I wont swear to that though, I didn't look at mine very close when I had it out. It would just be a lot easier to produce with a round hole, yours is oval, and has a bevel cut around the edge, making me think someone's messed with it, not to mention how it extends into the threads.

 

[HIGHPSI4]

The bolt has been over torqued and has elongated the hole. Won't be long before it snaps off in the head/center cartridge.

 

[dsmtalontsi95]

couldn't you just drill it then?

 

[dsm-onster]

Wow. Looks like a muh bigger hole. Oil volume is a big ussue not just pressure. The pressure must be measured at the cartridge for the sake of guaranteeing the volume is present to spupply the turbo. . . Of course given that the outlet is up to spec. . . So many guys are out of spec on the outlet.

 

[95burgundyesi]

This bolt was bought off someone when I ran a 14b off the head. I don't believe it was torqued to where the hole was cutting into the threads, the head of the line would have to be crushed for it to go in that far I would think. If the hole was drilled out, it was done by machine because my dremel skills are not that good, I I consider myself a dremel master

I am running a -10 5/8 blue line from extreme psi. In the "too small return thread" they say holsets need -14 returns. So I guess my return it out of spec.

 

[95burgundyesi]

Can someone point me to the T fitting so I could run the pressure sesnor in the line and not off the oil filter housing.

 

[brian9397gsx]

the bolts from extreme psi if im thinking correctly are smaller because the 1g line has a restrictor in it were as there line does not. i believe that is why the banjo holes are smaller.

 

[kawboy]

White smoke can be oil also

Some synthetics burn white, Mobil 1 Synthetic for example.

But to me, your problem sounds like valve seals. Extended idle oil burn is something I've had before and new valve seals always fixed it.

Summit and JEGS sell -4 t fittings with 1/8" NPT treads for the sensor.
