THINGS TO KNOW ABOUT
TURBOCHARGER INSTALLATIONS
Damage to a Turbocharger is generally a secondary result. Turbochargers are asked
to perform in some pretty hostile environments. Any preventive measures taken at the
time of installation may prevent damage. The following items should be taken into
consideration for a proper turbocharger installation.
1.
Be sure the turbocharger is receiving oil from a filtered source.
2.
A quality paper element style oil filter is recommended.
3.
Be sure the turbocharger has a properly sized oil feed line.
4.
The oil return line size needs to be a minimum of a -10AN or 5/8 of an inch
inside diameter or larger.
5.
Install coolant lines if applicable.
6.
There should be at least 1 inch of clearance around the turbocharger and any
structural member of the car.
7.
There needs to be at least one flexible rubber style compressor cover discharge
tube coupling.
8.
A ported shroud compressor cover should be utilized whenever possible.
COMMON CAUSES OF TURBOCHARGER ISSUES
Turbochargers leaking oil and smoking. Turbochargers will leak oil and smoke due to
multiple reasons which are typically installation related.
1.
An inadequate oil return is the primary cause of oil leakage.
The turbocharger needs to be mounted as high as possible so the oil will
gravity return back to the engine.
The oil return line needs to be a minimum of a -10AN or 5/8 of an inch inside
diameter.
Try to use tube type hose fittings that do not have any restrictive tight radius
bends.
If utilizing an oil return pump the pump should be mounted lower than the oil
drain on the turbocharger. It may also be necessary to have an oil reservoir
installed in the oil return prior to the pump. The return oil from the
turbocharger may also contain air bubbles. The air bubbles may have to settle
out of the oil before the pump will pump the oil.
If utilizing a oil return pump in the system and if the pump is not size properly
or if there is excessive crankcase pressure this may cause the turbocharger to
leaking oil.
