I noticed my truck idles warm at around 600 rpm, and the oil gauge shows at idle about middle of the first bar, then fluctuates to middle or more of the middle bar when im driving.(if that makes sense)

1) is this normal? Im not used to older gauges, and have never seen such a fluctuation, although I under stand as the revs increase so does oil pressure.

2) whats the normal rpm's for idle at warm?

 

IF you connect a mechanical gauge, you should get 7-10 PSI at idle, 750-850 rpms, and a minimum of 35 PSI at around 3500 rpms. These are not 'hard' values but you should never see less than 7 psi at idle and should see at least (RPM's / 100): 3500 rpm- 35 PSI, 4000 rpm- 40 PSI, etc..

 

yeah your fine.

 

alright. I mean, theres a tick to the engine, thats either lifter noise, or an exhaust leak at the manifold, or just a typical tick to toyotas. But I thought, maybe it might be low oil pressure.

 

Mine reads 0 after its warm

 

Im going to take a small vid clip of the ticking, and let you guys tell me if its a typical toy tick, or if im running bad lfiter noise.
