Garrett GT28 Banjo Bolt Oil Restrictor Size

[Lukezen27]

To save any confusion, for best results when using a Garrett GT turbo,
Use a 0.6mm restrictor in the oil feed line.
Be mindful the following should also apply,
The oil drain must be of adequate size & free flowing without kinks or dips.
Try to drain back to sump above the oil level.
The B16A~B16B~B18C lend themselves well to this with an available boss on the block that can be drilled & tapped to accommodate an AN fitting.
(To the left of the dip stick – lower portion of block)
Also, don't mount the turbo more than 15deg off horizontal - shaft orientation.

If the GT is leaking from the rear, fit the restrictor & it should fix itself…
The rear seal is carbon.
If it’s from the front, Bad luck

Hope that helps

Thanks Adrian

The smallest I could find was 1mm and I've installed that, no more smoking out the tail pipie

Where can we get the 0.6m restrictor?

Mine was leaking both front and back
