Another 100bucks to the Boost Gods

[WDRacing]

Is it me or are those ba$tards greedy...I blew the turbo real badly, lack of lube, or should I say to much suction on the return side. Oh well, I get to do my first turbo rebuild. Perhaps a DIY article is inline, I need a damn Camera though.

Oh well, I'll be boosting hopefully by next year...lmao.

Between me and Fiz, you guys better be learning somthing, we're spending alot of money...lol.

The turbo gods are mad at you for not taking pics.Once you take pics of your setup then they will be satisfied.Go buy a digi camera.You got a scanner?Then get the cheapo and develop then scan.I'm waiting till you guys got everything right to minimize my chance of problems.I'm thinking of double tubing all my lines so if one breaks there is one to keep it from leaking.

100? You got away lucky... My last screw up cost 365!

i guess i can ditch the return pump idea. sucks that you had to waste a good turbo. are you having the turbo balanced after the rebuild?

Hahaha for a second there just reading the title, I thought you were going to send me 100 bucks!! har har har

So it was too much suction on the return side that did it? Damn, who knew...

I guess it will be more obvious once you pull the thing apart, how the seals are worn.

I was thinking about the design though, it is a good idea. Couldnt you still do it, just have oil that comes out of the turbo go into some sort of catch can, and then suction seperatly from that? That would save you from having to apply any sort of suction to the turbo itself, just make sure that you can keep a small supply of oil in the catch can at all times, and you'd be able to return oil to the engine in the same manner through the filler cap... Watcha think? I have a catch can you could use...

gimme your bible =/ i wanna read it

The problem I'm having is not knowing how much oil to keep in the turbo. I could put a restrictor in the return line, so the pump can't suck all the oil out, but how much oil is enough? It'll drain a resovoir with the quickness, not to mention where the hell will I fit one?

I'm probably going to pull the pan and weld on a oil return bung....

I already pulled apart the turbo, it's shot. Bad bearings, bad exhaust housing seal, bad compressor seal and some shaft wear, within limits on the shaft though.

I'm not balancing the assembly after, it isn't required if you index the the parts on removal.

Sorry about the turbo. It has potential though. I think you are close to having something great there. Consider it R&D, every good product has to have good R&D!!

You could have the pump turn on and off with a float switch in the reservoir, so you'd never drain the thing completely! Comeon man, lets make this overly complicated and ridiculous! Nobody wants to have to pull a damn oil pan and weld in a bung... You could put the reservoir right where the AC compressor goes...

HAHAHAHAHA...very true man.

I posted this a while ago, maybe you can find some usefull things in there.It never made it to a sticky, but... it helped me rebuild my own turbo so maybe it'll help you too. I balanced my wheel and got my rebuild kit at turbocity, btw. Good guys over there.

Usually whenyou take off a used wheel asembly, there is enough stuff on there (carbon, etc), that rebalancing it is a good idea upon re-assembly. Those things are usually balanced at 100,000rpm. Then again, if you can get another one for 100 bucks, what the heck...

When I rebuild mine I'll include your thread and info. Thanks man. I hope to have a good writeup for everyone to use.

Each time I bust my motor (3 times so far) it costs me aprox $1k-1.2k. And the down time for getting parts from the US just sucks.... strangely enough I starved my turbo of oil once (when I blew a headgasket) for at least 10min of hard driving + another 15mins of going-back-home-on-the-road dirving but the thing just keeps on ticking... no busted seals or anything.
