Can turbo seals be replaced?
Seals can’t be repaired, sadly. You have a few options. A replacement turbo can be found, the center bearing assembly on your existing turbo can be replaced or upgraded to a larger turbo, or you can send your turbo in for re-manufacturing and they will do so to their specifications.
How do you know if your turbo is leaking?

Can bad turbo seals cause white smoke?
White smoke from the exhaust usually indicates a leaking turbo. The white smoke is usually caused by the turbo leaking oil internally, but it can also be caused by internal coolant leakage. White exhaust smoke is frequently the result of valve leakage.

Can a bad turbo cause oil leak?
The bearing and turbine shaft are kept lubricated by positive air pressure in a turbo. As a result, air pressure can be affected by restrictions at either the compressor or the turbine end, leading to oil leaks.
How do you test a turbo seal?
Fill it with oil, close the ports, and watch it for leaks for a few days on the workbench. In a bucket, fill with oil, rig up a feed line (plus a restrictor) to a small oil tank that I can pressurize with air in order to pressurize and force the oil into the turbo at Xpsi over a period of time and then check for leaks.

Should there be oil in turbo pipe?
A small amount of oil in pipes is normal. Excessive breathing, as previously stated, or, more likely, leaking turbo seals on the compressor side are the most likely causes of the shaft play that you’ve observed.
Does white smoke always mean blown head gasket?
