Turbo Rebuilt Kit

[And_44]

Howdy ya'll. My seals on my Turbo are going out. Getting an unseen but noticeable oil leak. I have no fresh oil leaking on external of engine and when I remove the intake off the turbo I have a nice small puddle of oil pooling. Fortunatly I have no shaft play and turbine spins pretty freely. Figure it's the seal on turbo as it will burn it through the combustion and be unseen.

My question is. I have the 6cm TD05 housing with a 16g compressor wheel (big small big small fins). Which rebuild kit do I need to get? One for a 14b or a kit for a 16g or do they make kits for these type of turbo's? 14b to 16g conversion? Was looking at Mitsubishi Kits at their rebuilt kits as they mention that the Mitsubishi TD05/TD05H/TD06 Complete Superback and EVO Rebuild Kit goes with a 14b to 16g conversion but just not sure.

If this doesn't look like the right one could anyone point me in the right direction for a rebuild kit for my turbo?

Thanks in advance for any insight you wise dsm'ers can give me

Ok,

So to clarify my question some. I'm gonna go with a kit from Mitsubishi Kits just curious if anyone know's how to tell without taking apart the turbo if it's the Superback or Flatback. It's just leaking oil so gonna do the rebuilt and skip the balancing as the wheels appear to be in great condition.

I don't have the answer to your rebuild kit questions unfortunately, but before you go to all this trouble how are your vacuum lines connected coming off your valve cover? In the picture below you can see the blue vacuum line running from the side of the VC to the intake, this is the vacuum line I'm talking about. If you have yours hooked up like this your turbo might be perfectly fine, the oil in there could just be from blowby. If this is the case you can temporarily run a small filter on the side of your valve cover (the ones you find at AutoZone) and just put a rubber cap on the intake hole. Clean out the oil thats pooling at the turbo and run it for a few weeks then pull off the intake and re-check for the oil thats pooling up.

Buy this kit:

Mitsubishi TD05 TD06 Major Turbocharger Rebuild Kit

It has the compressor seal collars for both the 14B and 16G wheels. If your compressor would happen to be flat-backed (all 16G wheels are NOT, but some of the 17C and 19C hybrids ARE), you would have to reuse your existing oil shield.

Gofer. Would that happen to cause me loose as much as 1 quart of oil about every 200-300miles?

Jusmix141, thanks for the link. I bookmarked it.

If it turns out to be a simple burp back into the system. Which I hope it is. Then I'm in luck. The guy I bought the car from in Feb upgraded the turbine on the 14b to the 16g turbine but not sure if he did a rebuild starting to think he purchased and installed just the 16g turbine. So it could be the original 14b and seals.

Can't be, unless the guy's a moron.

You'd have to get the center housing machined for the 16G compressor to fit....there's no way this could have been done with the center housing still assembled without getting metal everywhere.

Make sure you're using a 1G feed line and feeding the turbo from the head, too. MHI turbos do not like excessive oil pressure too well, so feeding a used 14B or 16G from the filter housing is not a good idea.

No thats an excessive amount of oil, unless your getting a ridiculous amount of blow-by... Which would mean that if you did a compression check the results would be no good. Is the valve cover pushing the blow by back into the intake like that blue vacuum line in the picture?!?

It sounds like the gentleman you bought the car from told you the turbo was something that it was not. A 14b, small 16g, big 16g, & Evo III 16g all use different compressor housings to accommodate the size of the compressor wheel. Like Justin said, the odds of him machining the housing to fit the bigger 16g wheel is slim to none. To verify what type of TD05 turbo you've got on there check the part number on the side of the compressor housing...
I copied these from a tech article on the site.

I'll be checking the number here as soon as the car cools some. The hot side of the turbo has the 6cm housing, previous owner could of installed the 16g housing on the cool side with the blade. Just the blade ain't the stock 14b blade with all the same size blades. It has the small big small big. Which I assume to be the 16. And the oil is getting burned or something it could diffently be that hose though, with the car sitting a oil drip never occurs. When the valve cover comes under pressure from boost it could be pumping that oil into the intake. If I drive the car without boosting much the oil level stays pretty constant but after extended periods of boost the oil level drops. And this all started after I replaced the PCValve on the back side of the head. Any who. Car drives great, I'm always checking oil and always keep fresh oil in car to top it off. Just getting annoying loosing oil.

Yes, all the coolant and oil lines are set up like stock. Oil line is running from the bottom side of the lip of the valve cover. I do know the oil gauge in car is inaccurate but when cruising it is usually 3/4 of the way to the mid range notch.

My guess is that your getting excessive blow by, especially since your just replaced your PCV valve. Read through this and get an oil catch can setup, that way you keep the oil out of your intake/turbo.
PCV Valve System

 

[And_44]

Well I'll be. Anyone recommend a good system for a catch can set up? I want to keep the system together but wanna catch the oil before it hits my intake, easier to meter how much oil I'm loosing as well.

 

[gofer]

Catch can setups can be pretty pricey and removing that hose and running one will fail emissions testing, if you have any? I suggest spending a few dollars on a universal fuel filter from a car parts store in between the valve cover (VC) and the intake. It looks like the picture below and they really are at every car parts store, once installed you can kiss all that oil in your turbo goodbye too! Then once you get some more modifications and figure out why your getting all that blow by (do a compression check) then drop some money into a catch can. This is just a suggestion though, of course you can take any route you want to take but this in my opinion would be the easiest for you.

[And_44]

Will do that. No don't have emission's to worry about emission exempt. I'll try to find a compression tester I believe I can rent one or probally pick one up pretty cheap on CL. Thanks for your input gofer. This filter if it helps is a heck of alot cheaper it seems then doing a turbo rebuild. LoL Anyway. Thanks again.

 

[gofer]

Your welcome, I'm always glad to help. Work smarter not harder, and its a lot more work removing a turbo and rebuilding it just to install it and watch oil settle at the compressor wheel again. Good luck and let us know if that helped...

 

[And_44]

So been doing some reading/researching and a very good possibility is the PCV its been said and I've read many times that after 10psi they leak. Well after I modded my BCS removing the restrictor my boost went up from 8~9psi up to 10~11psi. Yes I still use the stock BCS, not modded enough to really care for higher boost;D At same time is when I installed the new PCV so gonna get an inline fuel filter for VC to intake and a check valve for inbetween PCV and IM. I'll keep ya'll updated.

P.S. Gonna get a compression tester from Harbour Freight this friday.

Found out the oil leakage was from a plug from an oil galley next to the thermastat housing on the head, and the oil return line had a minor crack in the flex section. Turbo turned out to be a small 16g from a Galant.
