Life is Supra · 07-17-2011, 11:13 PM

Hi guys,maybe I have a stupid question(for u)but I must ask.I plan to rebuild my ct-26 very soon and with what I must clean intercooler core and pipes because there was an oil leak on turbo.Thanks in advance

kerosene is what you will use.

Couple of things...

First, not sure of your background or equipment, but unless you have some precision, high-end equipment rebuilding a turbo (CT-26 or any other) you're asking for serious trouble. Given the very high RPM's these things spool up to, the rotating assembly has to be balanced EXTREMELY well to avoid damage or destruction to the turbo and potentially the engine as well. I sincerely recommend sending it off to a reputable company to rebuild it for you unless you have the experience and hardware to do it.

For cleaning your intercooler and pipes, you can even use gas so long as you dispose of it safely afterward. Just for the record though, the type of bearings and seals used in the CT-26 will always allow some amount oil to pass through into the intake pipes and eventually accumulate in the intercooler. That's the case even on newly rebuilt units, so don't panic when you see it later down the line. Unless it's really a LOT of oil, it's normal.

I just assumed he was taking the turbo to a dealer.. thats what I would do. or send it into driftmotion.

mirage83 · 07-19-2011, 09:05 PM

Driftmotion, seriously. And go ahead and do the 57 trim upgrade while he's at it.

I just get real uneasy when someone says that he's going to rebuild his turbo. Those things spin up too fast for comfort if you're not 100% sure of the balance.

you need a machine to balance them properly I think he was thinking more along the lines of re doing the seals. I think they sell something like that on ebay. I just don't fiddle with it.

I've yet to see a turbo which doesn't use a sacrificial oil seal. They all let some oil through... same for cam seals, oil pump seals and main seals.

Even replacing just the seals is somewhat risky as you still have to dismantle the turbo and then get it back together EXACTLY as it came apart.

i noticed that at the back of the valve covers, there are 2 breathers which lead into the accordian that leads into the turbo. in my sight wouldent that just blow oil into the turbo, isent that a bad thing?

I'll make this short...

NO.

i know there only for emissons but it kinda seems kinda useless but yet again everything that is emmisons is mostly useless for performance
