Quick Answer

Your Question What is turbo oil return line?


Gates Turbo Oil Feed and Return Lines are designed for oil conveyance to and from the turbocharger. Developed to handle the extreme temperatures found in the turbocharger system.

Where does the turbo oil feed line go?

The turbo oil drain is a pipe that connects your turbo chargers oil gallery to the engine, this drains the oil away from the bearings inside the turbo charger. The pipe is connected typically to the sump or the lower portion of the engine block.

What can happen if the turbocharger oil return line becomes restricted or blocked?

If the oil return line from the turbocharger is blocked it raises the oil pressure in the turbo charger which then escapes past the oil seals at either end. The oil then enters the intake tract where it is sucked into the combustion chamber or it is blown out the turbine side into the exhaust.

How do you install turbo oil return line 6.7 Cummins?

Turbo oil drain tube 6.7 cummins, easy install.

How do you make a turbo oil return line?

How to make a Custom Turbo Oil Return Line DIY

Do Turbos have oil lines?

on December 2, 2021. Oil from the engine lubricates the turbocharger bearing system. This oil is fed into the bearing housing, through the journal bearings, and through the thrust system as well. As a coolant, the oil also acts as a way to remove heat generated by the turbine.

How do I remove oil from my turbo pipe?

How To Replace Turbocharger Oil Supply J Line

Why does a turbo leak oil?

Oil leaks can be caused by a variety of factors, the main factor being incorrect pressure within the compressor and turbine housings. Oil leaks can cause catastrophic damage to the bearing systems and occur within seconds of the turbocharger commencing operation.

How do you lubricate a turbo?


Pre-lube the turbocharger prior to first start up. With engine NOT running
add clean engine oil to the oil inlet of the turbo while turning the shaft by hand until oil comes out of the drain. Use of a squeeze bottle or pump can is recommended to expedite this process.

What are the signs of a turbo failing?

Turbo Failure Symptoms

  • POWER LOSS. If you notice that your car isn’t accelerating as powerfully as it used to, or is slow to react to your input, this might be a sign that your turbo is failing.
  • WEAR & TEAR.

What happens when a turbo blows on a diesel?

The most common signs of a blown turbo are:

The acceleration of your car seems slow and noisy. Your car doesn’t maintain high speeds easily. There’s smoke coming from the exhaust. There’s an engine fault light on the dashboard.

How much shaft play is acceptable on a turbo?

While there is always going to be shaft play in a journal bearing turbo, the allowable tolerances we’re talking about is 0.003″-0.010″ which isn’t much to really notice. If you have 0.020″ of shaft play, the bearings are worn and it’s going to wear at a much faster rate as opposed to bearings that are within tolerance.

Does my turbo need a restrictor?

Journal Bearing Turbo

An oil restrictor is generally not needed except for oil-pressure-induced leakage. The recommended oil feed for journal bearing turbochargers is -4AN or hose/tubing with an ID of approximately 0.25”.

How much oil pressure does a turbo need?

Oil pressure entering a ball-bearing turbocharger needs to be between 40 psi and 45 psi at the maximum engine operating speed. For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040″ diameter orifice upstream of the oil inlet on the turbocharger center section.

Can you run a turbo without coolant lines?

doesnt matter which side is which because the turbo doesnt have an IN or an OUT. You can run it for a little bit without the coolant lines. If you need to have the car up and running it should be fine.

Does a turbo need oil and coolant?

When the engine is running, the oil is a coolant that draws heat out of the turbocharger. But, for the oil to cool the turbo, it must flow. Restrictions in the oil feed or return lines can cause the turbocharger to operate hotter than normal.

Do you need to run coolant through turbo?

If the turbocharger’s center housing has threaded ports on either side, at 90° from the oil inlet/outlet flanges, then it is water-cooled. In order to meet durability targets defined by Garrett engineers during its development, it needs water flowing through it.

How do I prime my new turbo with oil?

disconnect the ECU and turn the key and let the engine crank.. this will pump oil into the turbo while not letting the engine fire/start up, that is what is recommended from the install instructions on the AWE KO4 kit before you run the engine for the first time after installing the turbo kit.

How do you prime a diesel turbo?

WARNING, Purge the turbo after you installation and before …

Is my turbo burning oil?

Oil can get into your exhaust if your turbo unit develops cracks, or damage to its internal seals. The extra oil will burn off in a blue or grey hue. You’re more likely to see these heavy fumes when using the turbocharger. Rev your engine and see if excessive smoke is emitted.

Can a leaking turbo Be Fixed?

It could be so simple: if oil seeps from the turbocharger, it is leaky, gets replaced, and everything is fine. Yet, the fact is: if only the turbocharger is replaced, further repairs will usually be needed within a short time.

Can a bad turbo cause oil leak?

Turbo relies on the positive air pressure for maintaining the oil lubrication of the bearing and turbine shaft. Therefore, restrictions at either compressor or turbine end can affect the air pressure, and that causes the oil leaks.

Do Turbos need to be lubricated?

Lubrication is essential for turbochargers, which rotate at extremely high speeds to boost the engine’s power by forcing more air into the combustion chamber.

What oil should I use for my turbo?

What Is The Best Oil To Use In A Turbocharged Engine? It is recommended to use Mobil 1 Turbo Diesel Truck 5W-40 oil for turbo diesel engines. Truck owners who rely on their oils to ensure the best performance from their engines, including turbo engines, are highly loyal to this company.

Is synthetic oil better for turbocharged engines?

“With its superior resistance to deterioration, AAA’s findings indicate that synthetic oil is particularly beneficial to newer vehicles with turbocharged engines and for vehicles that frequently drive in stop-and-go traffic, tow heavy loads or operate in extreme hot or cold conditions.”
