The Best Way To Go About Fitting Your New Turbo And Ensuring Its Going To Go The Distance Is,

  1. Measure & Verify Your Hot Oil Pressure (Hot Idle & Hot 2000RPM), This Will Confirm The Oil Pump / Bearing Clearances Are Correct And Your Turbo Wont Drop Its Bearings After 2 Mins Of Driving.
  1. Measure & Verify Boost Pressure, This Will Confirm That There Is No Overboost Present And Will Also Confirm If Any Boost Leaks Are In The System, Both Can Lead To Premature Turbocharger Failure.

Replace Your Engine Oil / Oil Filter & Air Filter, New Oil & Oil Filter Will Ensure A Clean Stream Of Oil To Your Bearing System, This Is Critical If You Have Had Leaking Injectors And The Oil Has Turned Gritty And Or Sludgy.

  1. Exhaust System Is Another Critical Part, Bent Exhaust Manifold Flanges Are Super Common On Some Vehicles, This Often Makes a High Pitch Squeal That Replicates a Faulty Turbocharger Often Confusing People. DPF & Catalytic Converter Blockages Often Cause The Turbine Side Of The Turbocharger To Overheat And Or Melt, This Part Must Be Checked Or Cleaned Out Especially If Oil Or Water Has Gone Through It.
  1. Intercooler & Pipe Work, Intercoolers Get Filled With Oil Overtime Due To Blow-By Passing Through Them, When Doing Your Turbocharger It Best To Remove And Clean It Along Side A Pressure Test To Ensure Its Not Leaking. The Pipe Work Is No Different, Remove & Clean And Also Inspect For Cracks / Splits.
  1. Oil Lines, Oil Lines Would Have To One Of The Most Critical Parts For Your Turbocharger. This Item Should Always Be Replaced When Or Cleaned At A Minimum, This Part Often Gets Oil Coking In the Bends Due To Its Small Inner Orifice.
