Turbo blowing oil.

[dennis]

I have the little KKK turbo K24?? I think. My question is other than just repairing this one, what hybrid options do I have or bolt on upgrades are possible. The engine is a stock 1.6TD from an 85 Jetta mounted in a Caddy. I don't really want to spend a fortune but want the best bang for the buck. Will 1 1.6 TD T-3 bolt up to my exhaust manifold?
Thanks
Dennis

yes a T3 from a 1.6 diesel will fit your manifold.  K14, K24, and T3 (if from a vw diesel) will all have the same flange.

T2 also takes the trapezoid flange. K03 is basically the only one that doesnt fit.

[dennis]

Sounds like T-3 is the way to go
Thanks fellas

What's the goal though?  A T3 isn't any better or worse than a K24 - they're essentially the same turbo, hence why VW used them interchangeably.  They're both built to the same specs and have pretty much the same boost curve and everything.

Have same K14 on my AAZ.
How would one know if it is the turbo blowing oil ?
I do have some oil coming from the valve cover vent
but I have serious consumption from what i think is
the turbo. Has about 375,000 km on it
and smokes like crazy when it boosts hard.
The smoke is greyish and not the black soot
you get when the fueling is turned up on the pump.
Not much smoke at all on start up, just the typical
diesel smell with a constant rich oil smell coming from the
car at all times when it runs.

. After posting this I found some of the oil is coming from the valve cover vent. I am going to install a catch can prior to condeming my turbo.

I may be wrong but I was under the impression that I could make a hybrid from a T-3

what are you going to breed it with?

you can make an easier hybrid out of a K24 and a K26. parts bolt together.

Don't know yet. Im relying on you guys to tell me.

I thought the individual who did the K24/K26 hybrid found it didn't flow as well as their K24 had before hand... Could be wrong though.  My "impression" is that the K26 (as found on some Audi diesels) isn't particularly desirable compared to our K24's...

I read the same thing about the K24/K26 swap. According to some of my gasser buddies their are more possibilities with different compressors for the T-3. I have owned quite a few NA diesel Rabbits and Caddys but this is my first Turbo 1.6. If the consensus is that the K24 is best then I will stay with it. If there is a better set-up then that is what I want to work toward. I got stomped at a stop light last night by a Chevy S 10 so now my need has become a bit more urgent. I smoked a lot if innocent people behind me though. I have not screwed with my pump yet, but I won an auction on ebay for an EGT guage a couple of days ago so I though that when I get the manifold off to fit the probe I might as well bolt up somthing different in the way of the turbo if I have enough stuff laying around to do it. How much boost will the K24 efficienty produce without sacrificing flow? Gonna have to do something about that tranny too. 1st gear is useless, 2nd is almost as bad. In 3rd 4th and 5th it pulls really well. I have a 9A with a Quaife differential I can get for $200, but it is need of some repair. I will probably get it for the diff at that price anyway, but I don't think I can shift fast enough to win any races with that. Oh well, Im starting to ramble. I do love this forum. This is the largest pool of experience I have found on the web.

If you're looking for stoplight performance than a smaller turbo would actually be better - the downside to the K24 is it doesn't really even start spooling up till 1800-2000 RPM.  The smaller turbos (K03 and K14) start spooling sooner, so you get boost at lower RPMs.  If we were talking in drag racing terms a smaller turbo will give you better 60-foot times for instance...

The "best" is a VNT, all the fun of a big turbo with the lower RPM performance of a small turbo.

[dennis]

I'v not even adjusted the waist gate yet to get more boost, nor have I turned up the fuel. From what I'v read here I need to get that EGT guage in before screwing with it. All I have now is the stock speedo, fuel guage, and the standard idiot lights. What is the deal on the "Giles Pump" I read so much about? Is it worth the expense or is this something I can do myself?

[vanbcguy]

Yeah, an EGT gauge is a very good idea before messing with fueling.  Without it you have no idea if you have enough fuel, too much fuel, or if you can add more fuel. 

Giles is a diesel wizard.  He builds performance injection pumps for all types of diesels and is a master at what he does.  When you get one of his "super pumps" it's build up for YOU, ie what style of driving you want to do, what kind of turbo you're running, how big your intercooler is (if you've got one), how heavy your vehicle is, you name it.  That, and the pumps he builds are tuned for the fuel you'll actually be running, whereas the stock pumps are tuned for 1980's diesel fuel which doesn't exist anymore.

The long and the short of it is you can't really build a pump the way Giles can.  He's got a flow bench, he can set up the dynamic timing, and he's got access to the full range of "stuff" that can ever go in to one of these pumps (ie camplate, advance pistons, springs, etc etc etc).  We can "guess and test" but he can scientifically build the pump.
