Has anyone ever rotated the exhaust and intake of the rb20 turbo.

i had to to fit mine to numerous things and i must be doing it wrong, as they seem to last about 1-2 months before a seal is broken and oil is spilling into my engine.

given this is the second time, i dont want to have to take the next one off in a few months i want it to last.

The exhaust housing has a fire plate underneath the exhaust housing, rotating this providing you don't chip the ceramic turbine wheel will give no problems.

The compressor housing has a metal gasket which has a sealer paste holding it in, spinning this can sometimes push the dried paste into the line of the compressor wheel. Not so common.

Where you would go wrong though is if when you spin the housings the cartridge is not North/South with the oil intake above and oil drain below you may run into problems as the junk in the oil stays in parts of the cartridge and cannot be gotten rid of and is constantly lubricating the bearings.

Other then that, they are 20 years old, they have done their job and are and will all eventually die.

All contact style bearings especially when combined with a ceramic turbine will fail after this amount of time and in many case much sooner.

If your oil pressure is poor to the turbo and its not lubricated properly you will fry the seals and they will wear down without the oil buffer.

Take some pictures of the turbo that failed and it could show the problem.

Hi

Thanks for all the info.

The reason i rotated it was to have the oil on top and the drain below, as it was fittest to a patrol not a skyline.

It has been blowing oil into the intake. its been doing it for about 2-3 weeks i guess but on the weekend it was blowing so much the diesel engine was 'missing'. It was shooting so much oil into the intake the poor diesel engine dident have enough diesel in the cylinders to compress / combust correctly.

I will post pics when i remove it on the weekend.

It may very well be coming from the breather at the head caused by blow by.

Check the down pipe that runs into the turbo intake for oil or setup a temporary catch can just to see if it is the cause if you have not looked at this.

      Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 馃ぃ, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up

      Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.

      We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
