Low Oil Pressure and Top End Engine Tap

also back up the comment about the filter above, have spoken with a few blokes that work on the TD42 Deisels "yes different motor" but they say that some aftermarket filters play havok with oil pressure readings and that genuine nissan filters are the only way to go. Even the bloke at the nissan parts counter told me that the aftermarket filters are way too high flow and the genuine ones are more restrictive, hence the better oil pressure reading. Would be nice if it was a simple fix for ya.

I think your best bet is to mechanically check the oil pressure. Remember, if your oil pressure is low, it more likely an indication of bearing wear or oil pump wear. Poor oil filters usually do not have an anti drain-back valve which operates properly. This allows the filter to empty of oil and delays the buildup of oil pressure on start-up. I have found Fleetguard to be real lousy filters. On the other hand Wix and Denso filters along with Nissan filters have worked very well for me in both rigs.

Thanks guys. I have been using ryco filters for the oil so i might get a Nissan one next time round. This change is 3000 km old and I will be changing it at 4000. The last oil change I did was at 2000. I have been using castrol rx super but I used valvoline super diesel on the last change. What is the best oil to use? I am open to suggestions. I think I may have found part of the problem. I was concerned that the engine seemed to be chugging with the noise coming from the air intake. I thought this had been changed in a service I had done but it would appear not. Taking the filter out quietened the engine down and the oil pressure rose to wear it would normally be but dropped as the engine warmed up. I don't know if it was because I could hear the turbo working but I felt there was more power when I took it for a drive. I will still get the oil pressure tested and a mechanical gauge installed but I may be lucky and the other symptoms could be filter related. Looks like a trip to the local Nissan dealer is on the cards. Unless someone knows a better supplier. Thanks for the help guy. I will give these options a go and see what happens. When I have givens Patrol a wash I will post up a pic as my avatar. Cheers

I have been leant an oil pressure check gauge. On the RD28T motor where will I find the sender unit?

Thank

Driver side, engine block, below No 5 injector, between the oil filter and the firewall, take care when unplugging!!
