Ok in that case i would go on ebay for a ko4 i hear they are of very high quality.

Options for the pretty much the same spec on the cheap is another k04. Or if you want to spend $1000, you could get a BNR stage 1 - thats close enough not to require a tune.

And if I were to get the 5858 or the bnr s1 would I have to get a retune?

No retune required for BNR stage 1.

I have been using a turbo (Ko4) rebuilt with ebay rebuild parts for 100K km (bought from former user on here that rebuild and sold them); no issues, but I am sure some of the kits are not as good as others.

The turbo swap was a little pain in the 6 cause he tranfer case is in the way underneath - that would push me to not want to do it too many times and get a decent turbo to start with.

Any recommendations for a rebuild kit,not sure if there is a lot of shaft play yet, haven't dug that deep but I know it is burning oil.

Since I bought the turbo built from another user, I dont know, but I do remember there was a post or thread he made/commented about exactly which kits he bought from ebay. Username was hhskinny1 I believe.

Edit I had wrong username. This guy:


And heres where he posts about the rebuild kit:

When you swap it out, leave the oil drain line on the engine!!! Just disconnect the turbo side!!! I wasted 2 hours trying to get that fucking bitch back on. I've heard you can do it that way. I also left the turbo mounting bracket on which allowed me to slide the turbo into place. From there I just installed the gasket and studs ect.

I have a non-smoking k04 sitting in my garage, but it has about 93k on it....

Mines got 114k, but I'm not even for sure it is the turbo, all I know is I have pretty bad oil consumption. There is oil in the intake piping and I don't really ever see smoke come out the exhaust.

Sometimes I'll look back after I get in boost hard and there will be a cloud of smoke behind me.

What do you think?

How much oil in the intake piping? Alot or just a bit? The stock cats hide alot of smoke. I'm using alot off oil too but no smoke. In my case it wasn't my turbo.

Last time I checked about 6/10 of a quart in 300 miles.

Pull your ic. if its the turbo seals you should have a really good coating in there and less so pre turbo piping. If its primarily pre-turbo to welcome to the rebuild club. That being said it would be a good idea to do a quick comp test, certainly easier and cheaper than buying a new turbo only to not solve the issue.

Thanks for the welcoming but I'm gonna decline lol.

Was planning on doing a compression test in the future just haven't got around to it.

People usually search and find excuses to go BT, in your case it seems like you just want to change the turbo. Just get this diagnosed properly, just in case the oil you found in the intake is actually stuff coming off of the crankcase ventilation system.

Doesn't smoke consistently, only sometimes when I get in boost.

Trust me I don't wanna go big turbo rn, don't have the funds. I just don't want to put a quart of oil in every 600 miles.

These symptoms are not necessarily consistent with a defective turbo either...
Do a compression test, it's cheaper. Once you will find the results you will be able to decide between topping up with a litre of oil every 600 miles, replacing the turbo or something else.

I also smoke a bit when I get into boost (so I've been told).

My turbo is relatively new.
Compression is 180-190, I don't recall the exact numbers right now.
Intake tract is dry. Pre and post turbo.
Both catch cans combined only capture about 1-3/4 oz of fluid after 3 weeks. (about 250mi/wk))
No noticeable amount of oil missing from crankcase.

Black smoke = running rich. Normal for our cars

Oh I'm totally blowing black clouds when I'm on it (low 11's), but I've been told there's oil smoke in there too. First heard about it on the way home from ENM this year. Then shortly after from a buddy that was following me one day. I can smell the oil pretty fierce too if I get on it and then stop at a light or park.

[btstarcher]

Check your compression. Oil in your intake is NOT due to a bad turbo. That's blow-by. Check (or just replace) your PCV valve also.

How do I check pcv valve?

You pull it out, and since you pulled it put a new one in. Then arrange a check-in to the bin for the old part.

[Fstrnyou]

Use caution getting the old one out. There's a retainer ring that pops off. If you break that, you're SOL unless you have another one.

If I remember right it rotates counter clockwise, I needed pliers to get a grip on it

I was skerred when I tried to replace mine. Didnt want to break that retainer, so I shook it around and blew in the tube to the manifold. Seemed to function properly, so I left it in.

Instructions unclear, dick got stuck in turbo.

Ok just checked if there was oil in the top part of the intercooler right off the turbo, the inside was definitely oily but wasn't pooled, as be expected.

Didn't take the front bottom hose off the intercooler to check, but I'm gonna assume there is quite a good amount of oil in there considering the hose is all caked with oily residue on the outside.

Sent from my XT1254 using Tapatalk

[Fstrnyou]

If oily residue on the outside is from oil build up on the inside, you have a boost leak. If you don't have a leak, the dirtyness is unrelated and no conclusion can be drawn as to what's on the inside.

Takes all of 5 minutes to take the intercooler off. Not sure what you're doing.

Didn't have time, and why would I have a boost leak, and how would I go to hunting down the boost leak.

New to turbo'd cars.

You're in Kansas. There can't possibly be that much going on where you don't have time to pull an intercooler.

Kidding aside...
I've never had a reason to do my own leak test, so I couldn't elaborate on how to do one. There are youtube videos though.

The outter dirtyness is likely years of road grime buildup.

I had to run from some tornadoes, you know, the usual.

The build up isn't from years of buildup because it is only on the bottom half of the rubber tube. Everything else around it is clean too.

Why do you say it is a boost leak though, I wouldn't think a boost leak would lead to me burning a quart of oil every 500-600 miles.

Did you ever do the compression and leak down tests to rule our other issues? Important.

If you really have turbo problems, a rebuilt K04 is an option if running stock tune and mods, about $350-$400. A better choice, which I did, is BNR stage 1, which is compstible with all mods that work with stock K04 turbo, including increased flow on intake and exhaust side (CAI, catless dp/rp, and K04 tunes like Hypertech).

No I did not do the compression test, have to go to AutoZone or something and rent it.

I just pulled the intercooler and there is some oil pooling at the bottom of the silicone hose connector.

I want to go bnr s1, but the monies ( high school). I try not to cheap out, but I will probably end up rebuilding the k04 if that is the problem.

And if it is low compression, I'mma ride her till she dies, then learn how to rebuild an engine lol.

You may end up spending more money by rebuilding the turbo compared to acquiring a new one. At least get a $400 ebay K04 which even though are most probably chinese they proved reliable over time (I think Mamba makes them).

Where have you seen these eBay turbos that are good, and will all k04's smoke at idle if I go 3 inch long pipe ?
