Rb26Dett Oil Pressure

[Rhysgtr]

Hey guys

This has probaly been covered but want to ask anyway. I just bought my first r32 Gtr and have been reading heaps about the oil pressure and has got me paranoid. On start up it seems fine sitting just over 2nd bar but once it's warm and I take it past 4000rpm it drops down between 1st and 2nd bar and then just stays there is this something I should be worried about and if so what could it be?

Cheers

Oil pressure depends on a number of factors. Some of the properties of the oil that affect oil pressure include how well it maintains viscosity under sheer (ie as it squeezes through the clearances), and how it does / does not handle extremes of heat (ie thermal breakdown).

Have a read through the "Goods on Oils" thread http://www.skylinesaustralia.com/forums/topic/22458-the-goods-on-oils/ for more info.

Oil pressure should not drop on full noise.

Oil pump dying. Have you changed the oil? Noises?

Before you get too paranoid you need to understand that the oil pressure sender unit is a known problem on the R32 GTR's. So you can either replace the unit with a known good one or get a mechanic to put a gauge on it for you. Do that before you do anything else.

The guy said he did the oils before I took it but I will definitely change it myself and that goods on oils link is good thanks for that. There's arnt any abnormal noises that I can hear but will try the sender unit and a new gauge first hopefully that's all it is. Thanks for the tips
