Re: D3-110 oil blow-by
Scott SV Tengah
When I remove the oil filter, it seems the oil is coming from the hose that I'm pointing at in the photo. There is some oil on the intake vanes of the turbo, but I presume that's from oil being sucked into the turbo. I presume a leaky turbo oil seal would manifest itself as oil leaking from the turbo itself rather than oil accumulating upstream, with respect to airflow, of the turbo?
The buildup/leakage is definitely from the bottom of the air filter housing.
FYI I max out at around 2750-2800 rpm.
