I just talked to one of the guys at works old man who says that if the bearings are jounral (or plain bearings) that they require full engine pressure and oil flow to bath the bearings and keep them lubricated. This sounds like the problem for all of us. When I tested with full flow it didnt leak at the rear or blow smoke only leaked at inlet gasket . Tell you what I find out when I fix gasket.

Good to hear you appear to be making progress but I fail to see in that above comment how increasing the flow/pressure of oil entering the core you will fix a leak you have at the housing to core interface???

Sorry if I have misread or misunderstood something you are trying to explain.

What is this guys credentials that you got this advice from, it sounds like he is just describing the oil delivery required for a standard engine bearing i.e. big end, con rod, etc.

As I stated in my post earlier, I HAVE fixed the exact problem that you and most others appear to be having, my car has been a 4AGTE for nearly 5 years now and my turbo is 5 years old and still performs perfectly, pretty sure I have got it sorted Wink

.

I will revise for those who missed it:

Ensure your engine has good crank case ventilation if this is not up to scratch the pressure created WILL force oil past turbo seals, housing to core interfaces etc.

Ensure your drain is of adequate size (>19mm) and is damn close to vertical ALL the way from turbo to sump and that it enters the sump at a steep angle, NOT horizontally. It also must enter the sump at the very highest point!

With the oil feed, most turbos have the restrictor integrated into the oil feed port on the core. If not, then simply chat to a reputable turbo outlet and ask what the restrictor size is meant to be for your particular turbo.

All pretty simple really.

If you follow the above I guarantee you the turbo on your 4AGTE will not have any issues.
