Re: D3-110 oil blow-by



The Volvo spec for D3 minimum compression is 22 BAR. I believe I would have the compression checked. If any cylinder is significantly below 22 BAR, you likely have some blow-by. Also, locate and check the Turbo Boost Sensor (it varies in different models of the D3). If it gets soaked with oil, you will have RPM issues, and possibly more problems. If it has been soaked in oil, replace it.
