Lurchy, doesn’t visually appear to be a lot wrong with your leak off results (although the total quantities weren’t calibrated measurements) so I guess you don’t have any serious problems with worn / sticking injector needless.Hi Victor,
I have done a injector bypass leak test and they seem to be equal as my video will show, there is no missing while the engine is running and the engine runs smoothly, i have tried to reach the area were knock sensor is located but with no luck, there is no codes logged also and the noise is only there on idle a few times then disappears the exact same cyclic noise on Nanone video, i will also look up a manual on the Antara you have to see if the engine is the same as mine, could come in handy, i will get the fuel trims checked, also the DPF is on the engine exhaust ports and the Catalytic converter is below that, the Pre Cat O2 is below the DPF were would the Post Cat O2 be located Victor,, thanks Victor,, Lurchy

On our vehicles the CAT is before the DPF, not after it - as a matter of fact the CAT is incorporated into the same casing as the DPF. The ones with a CAT after the DPF are the SCR CATs to tackle NOx emissions, our systems don’t have any post-DPF NOx treatment. Personally I’ve never even had cause to remove the heat shield from my DPF so couldn’t tell you exactly what’s in there but the locations of the pre- and post-cat temp sensor shown on the thread that gcmarcal posted a while back when he changed his DPF.
