Hi all,

Just a quick question. What should be oil pressure gauge indicate on idle and while driving, providing the engine is healthy?

Thanks!

my engine seems a sound one compression good and even across the cylinders, performance is good well it will pull to limiter in top so guess not much wrong with it. at tickover when hot oil gauge reads just above 1 bar when moving and again when hot 3-4 bar at around 3k when cold at tickover usually 5-6 bar when moving 4-5 bar at around 3k these figures are all affected by outside temp and gauge accuracy which i suspect is not that good

New Engine: Cold start, just over 3 bar in warm outside conditions, about 4 bar when cold out. Driving from cold is about 5 bar.

When hot at idle just over 1 bar, and driving about its about 3-4 bar depending on revs.

Previous engine sat at 0 bar when warm and 2 bar on cold idle, as did my valver.

Cool, thanks for that. Looks like mine is within the norm.

My hot idle is about 0.5 bar and driving about 3+. I'll top the oil up a bit and that should keep it out of trouble.

I had someone suggesting that if hot idle is close to 0 bar then the engine is gonna go BANG shortly. But I'm glad that's not the case. :D

guages are crap. more than often they dont even work.
so that could be your problem ;)

:lol: Fair enough. But I mean providing the one on my car works correctly, do I need to be alarmed?

I'll top the oil up today and check the reading again.

Hot idle can get down to 0, it depends on the oil used. That's normal on the F7R. Just make sure it get up to between 2+ to 3+ when hot running at 3000 rpm.

The hot idle was near 0 than 0.5. with revs i struggled to get it to even 3 bar when hot.
That combined with that rattle, and your oil smelling of petrol... :wink:

Topped up the engine with some good oil yesterday. Cold idle - 3 bar :D So It's all good now, no worries

computer says 1 bar at hot idle
4bars between 2.5 & 3k 8)

lmfao i think i could guess how much oil pressure that engine has more accurately than that gauge reports it!!

hmmm , this is a tough one really . :roll:
retarded heroin addict or shiney arse oil pressure gauge ??


i think i will stick with the gauge now mate .
thanks for the opportunity though :D

Mine always sits close to zero when hot at idle, never had a problem tbh.

are these gauges prone to failure?
mine shows 4 bar when cold up to about 80degrees, fitted oil cooler and due to temp going to 130 when on the track, didn't go much over 100 after fitting cooler but oil pressure dropped to 0 when warm, think the oil is ****ed or the oil pump is lazy. still lasted an all day thrashing.

thoughts guy's? its done 131k so me thinks its due a rebuild and possible turbo conversion.

dial/sensor has prob had it. if you had 0 pressure the engine would be very dead

thats what i thought, it was strange, any sensors available, part number price ?

Maybe the oil cooler is reducing the pressure due to the extra pipework?
