For a true seal the best set up is two gapless rings in separate grooves.
Do ceramic turbos need oil.
Because they elimintate the oil they also eliminate the parisitic drag that goes with it oil cook and are more durable.
This will seal very well.
Well worth the money trust me.
Full ball bearing turbos do not need oil thats the whole point they use cermaic bearings instead of oil.
Ceramic ball turbos precautions are not to allow impact on housing and to store horizontally.
By the time you notice its leaking there is not much hope for a cheap rebuild.
There is a down side though.
In this video i talk about ceramic bearings and do they need lubrication which is kinda what the title says funny that.
Things to check if your turbo leaks oil.
Turbo systems are made up of moving parts which spin at incredibly high speeds and work under intense heat and pressure.
A lot of those cars run 6 bar of oil pressure low turbos and sump pumps.
The ruby sapphire would be more resistant to impact and are also another 5 times harder than ceramic.
This means that they need a constant flow of quality engine oil to lubricate the compression valve and intake and outlet fans to reduce wear and help them perform at their best.
Ball bearing turbo cores have a restrictor in the oil inlet.
