I have recently been running my new 4agte in the garage and I have noticed under a bit of revs that the nissan t3 turbo is leaking from behind one of the retaining bolts on the turbine housing (connecting the beaing casing to turbine housing). This is leaking and is burning off as white smoke. The turbo is a recon but has been in the garage for a few years.
I am wondering whether the seals have died over the years or whether there is too much oil fed to the turbo.
The restrictor is 1.5mm hole but I tested whether the oil was dumping properly by removing the dump connection near the sump. There seemed to be alot of oil 3-4mm high out of 1/2" line. This seemed to be alot of oil for the turbo. I ran the engine without the connection to sump and it seemed to remove problem but I only ran it for short time because of amount of oil being dumped.
Could it be too much oil being fed and the dump cannot handle it? Would I reduce to 1mm or smaller? There is no pressure in engine as head has breather to air.
