Turbo "seals"

[MPFab]

It just flew all over me that I was trying to provide some potentially beneficial info and he is commenting on how poorly it was presented. Respected member or not, it was pretty pompous post.
I'm sure anyone who read it found mistakes I made in writing it. Several of you found merrit in it's content as well, and decided to comment on that instead. Thank you.
I'm done whining. I don't want this to get anymore off-topic.

OP good post. Sometimes one forgets T/C's are not common knowledge for everyone. I guess especially if this is someones first turbo car or the first time turbo is offered on a new platform.

This goes with the common threads:

How much boost can I run?
Whats the best Turbo Timer?
What BOV will give me the most power?

etc...

The threads that make us want to smack or heads against a wall.

obviously 5, whichever costs the most, and the loudest one.

If I put an intake fan (from ebay) after my turbo will it boost my boost while I make boost?

Exactly LOL

Just 1 r in merit

When I read turbo seals, I thought this would be about the aquatic mammal.

And especially quick ones at that!


I've only personally seen one turbo failure on a 1.4t (although it may be more common than I see) I'm not even sure what the exact failure was, but the compressor shaft was just flopping around and making a ton of noise. GM just has us sent the turbos back without disassembly so I couldn't really see what was going on.

It is integral to the manifold though, so the whole thing gets changed out.

I'm having a issue where my car is throwing a cloud of smoke after I let off the gas after being in full boost (13lbs) for a few seconds. No smoke during normal drive or under 8lbs. Anything over that a cloud of smoke comes out but only after letting off the gas. No smoke in full throttle.

 

[sonicR]

Me too!!!:sadbanana:

 

[6spdsonic]

What causes that?

 

[Preloader]

PCV problems. The inlet side of the turbo compressor is piped to the Positive Crankcase Ventilation. If the dipstick or oil cap seal is not holding, the velocity of vent through the PCV will pul oil with it.

Oil cap O-rings sometimes go bad. Check that first. Lastly, the Valve cover's PCV diaphragm has been a known failure spot on these. If that is the issue, GM will replace it.

 

[6spdsonic]

My intercooler pipping is also filled with oil

 

[Preloader]

Of course it is. Oil (that has made it through the PCV) has to go through the intercooler to reach the engine and ultimately get burnt out the tail pipe. Only when the throttle plate is snapped shut, is there a brief moment of extreme vacuum and velocity that can pull that oil passed the Intercooler which essentially is acting as an oil catch can at this point.

 

[6spdsonic]

Where's the pcv diaphram located?

 

[Preloader]

It's on the opposite side of the where the oil cap is. You have to pop the plastic cover off that covers most of the valve cover. Inspect around it for oil and wetness. If it is damaged, the whole valve cover needs replacing.

It's under the black circle opposite the oil cap:

 

[6spdsonic]

What if I replace that and it still smokes?
