Had to come back and give credit to this channel. Had a turbo burning oil after rebuilding twice. After this vid I disassembled unit conduct a visual inspection with no parts defect observed. Clean all parts and position rear seal gap as shown in this video. Reassembled unit and problem was solved. Great point.
I was having an issue getting the ring to pop back into the housing. I followed your way of doing it and it popped back in easily. Thx appreciate your help 👍
I`ve worked in a military turbo repair shop and never thought about putting the oil seal with the gap to the top for the oil. Good tip. And putting marks on the parts saves balancing. I can not order a bearing a seal kit in the UK off the top dealers without proof of a balancing machine in case it hurts their reputation if it goes wrong.
Design error to have to open the seal to get it over that flange. The flange should unscrew I would have thought. Anyway, so I am doing a man truck L2000 and wondered where I can buy seals
No, in a healthy engine this seal prevents exhaust gas from entering the bearing housing and then pressurizing the crankcase via the oil return line. If this seal fails, then it will manifest itself as blowby oil consumption. In this case, the dense oil mist from the pressurized crankcase will be vented through the pcv valve where it connects in front of the inlet to the compressor side and will be burned when it gets to the cylinders. However, if oil leaks through this seal, then it's a symptom of a different problem. Then either the oil pressure is too high, the oil drain is clogged/kinked, the bearings are worn and increased clearances flood the shaft with oil and overwhelm the oil return line, or crankcase pressure is too high and again the oil is not drained quickly enough, or some combination of these things.
That's bullshit no reason to align gap if it seals then it seals in any position. If it's a poor fit then maybe you can align it to leak less but it will always leak if it is a bad fit
@@hollarforadollar9244 its possible that putting the ring gap up reduces the chances of it leaking. I think you are both correct. If it's a bad fit it will definitely leak. If it's not oriented up it might leak as well. Kind of like how you have to orient piston ring end gaps 180 degrees from each other to reduce blow by. I would think that if you turbo drain is very efficient though it probably won't matter at all unless you are pushing massive boost and creating huge blow by. At that point you got a whole other set of problems smh lol.
i rebuilt my turbo a few days ago. I bought a replacement cartridge kit for it.. Stripped my turbo, fit the new cartridge, and on first start up, my exhaust was blowing clouds of blue smoke, idled poorly, had no power to drive properly, and dumped oil in my boost pipes.. and this was a brand new cartridge... is this seal that you shown, what is responsible for it? (As soon as i bought another cartridge and put that in, its all good now, just so you dont think its the way i rebuilt it).. cheers
When my car is idle i can hear the whistle of turbine through the exchaust all time, i guess it is bad cartridge :/ Where did you buy the new turbine cartridge sir? link would help :)
It will burn the oil for a bit bud. As long as engine sounds alright and rev up and you cam hear turbo spinning a little. Its all good. But Let it idle for ages. Then find a good hill near you goo up for a drive.. thatll help get your oil out. I think you chartridge will be alright as long as your last turbo didnt leave nasty filings. Did you check boost pipe before putting together?
yeah shit ass demonstration. Huge difference when the turbo is new. Many different parts can wear and change how easy they come apart and go back together.. This douche doesn't even know what hes doing.
AGREED,i was shown that on a $1OOOO turbo balancing machine many moons ago! ; BUT,if you do not re-balance it, is is not better to MARK the (balancing) nut first ? And how acceptable is it,will it work for many years?
C'est du grand n'importe quoi ta vidéo !! Une fois le turbo démonté du véhicule, autant en profiter AUSSI pour changer TOUS les joints internes !! Il n'y a pas qu'un seul joint qui s'use !! Vidéo sans grand intérêt technique 👎🏻👎🏻👎🏻
