Title: oil leak inside turbo
Post by: Shimy87 on April 21 2012, 12:20:29 PM
Have a small oil leak, must be internal on the turbo, oil escapes at connection between turbo outlet and intercooler. Very small. I was going to remove intercooler and flush out with some gasoline, I'm assuming there is oil built up inside it also.
 
Reason for concern???

Assuming you do not have the vent line from the end of valve cover to connected to the turbo inlet, then it is a seal in the turbo leaking and it will get worse.

If you do have the line connected, remove it and put a push in KN filter into the end of the cover.  Put a rubber vacuum style cap over the turbo inlet.

Flush out the IC and go on.

Vent line is not attached, its a seal :icon_confused: . Like you said, wait til the next issue comes up. Is replacing those seals a DIY job or do I need to take it somewhere. Looked in the manual you suggested getting and it seems pretty straight forward, but if I need a press or special tools I'm screwed.

instructions for a rebuild are on gnttype but I think I would suggest a rebuild by someone like John Craig at Limit Engineering or a replacement

When it croaks, if I'm going to have the expence I'm thinking ahead. At some point I want to add alchy. But thats it, no extreme build ups or anything. Should I get a stock rebuild or upgrade to a slighlty bigger turbo?
 
Thanks!!!

If you want alky, then a 49 or a 44 is the perfect upgrade,

You can pick up the CEA 5857...with is the equivalent of the 44 and 49 for the same price...but with all the newest turbo technology.

you might look around for a mullet that thought his twelve second car will run tens if he dumps the 44 or 49 and buys a bigger turbo.....a good used 44 or 49 will do the trick as well.  check the tb.com for sale ads

Steve, Full Throttle has the TE 34 57mm for $599...is that the stocker? If it is...mite be cheaper for him to buy it, than paying to have his rebuilt. He can throw alky at it later.
Title: Re: oil leak inside turbo
Post by: Steve Wood on April 22 2012, 08:05:17 PM
No, that is one step up from a stocker...not a bad little turbo...I ran one many years ago....it should make high elevens on alky.  For some reason, FT is only showing me one turbo today

Post by: Steve Wood on April 22 2012, 08:09:08 PM
okay, I see it...and also a 5831 billet for $649....I guess that is a billet wheel replacement for the 44?   Might be a good one as well.

Let's see if this link works from FT

I can't seem to get all of 'em to come up. The one on my previous post is for the 5857...which supercedes the 44 and 49.
Title: Re: oil leak inside turbo
Post by: Steve Wood on April 22 2012, 08:19:23 PM
it works, but way out of the range for what he needs....

the TE34, a 44, or 49, and probably the 5831 above would all fit his needs and combo. I would rather pay 400$ for a good 44 or 49 than pay for a rebuild on the original

I'm still using Patricks chart on the other board. He left Precision...so I'm pretty much lost on the new ones coming out. I'm not sure what the 5831 supercedes. Prolly best to call Mike and ask.

Post by: Steve Wood on April 22 2012, 08:33:43 PM
a search says it is a modern 44 or 49

Problem is that many of these modern turbos don't run any better than the old ones but they get a higher price tag
Title: Re: oil leak inside turbo
Post by: Scoobum on April 22 2012, 08:47:09 PM
Agreed...but sooner or later the 44 and 49 won't be produced. I'm trying to keep up with the new turbos...as the old ones are going the way of the dinosaur.

who cares if we have one that works and it is not available...it's all about the money as far as I am concerned.  I have a hard time telling someone to spend money on something that does no more for performance than something else that costs significantly less

Might try Mike at Full throttle and see what he has.....or what he knows....other wise post a wtb ad on tb and see what pops up

Was hopeing to put this off til next summer but the leak must be worse than I thought. Had it all cleaned up and drove about 200 miles and wiped my hand under where turbo and intercooler connect and its all oily again :(  I cant believe it can push it out that hose, its super tight?
Title: Re: oil leak inside turbo
Post by: Steve Wood on April 26 2012, 02:17:31 PM
must not be super tight :)

Once those hoses get oily, it takes some effort to get the oil off the hose well enuf to grip.

Check the turbo outlet and see if it is oily (inside of the outlet)
