ill just borrow ur motor then shall i

Should be fine. Probably a fault stock sender. Check out the many threads on oil pressure guages/senders being faulty.

Get a aftermarket oil pressure guage with sender.

if you have a warning light too for low pressure then yeah its probably low low pressure = bad but if its just the guage it could be the sender on crack

im not sure ive never seen any engine light come on....its a late 94 series 1 r33....would it have engine light?

i done a compression test few weeks ago and came up basically 150psi in all 6 cyclinders few psi difference between them

yeah it would definetly have a light

from memory its top left, red light

turn the car to ON but don't start it (so diag/test lights come on)

and look for a red light with an oil tin can icon

shows you the stock lights, its on the right side

could be anything. 1 bar at idle is a little low. the only real way to determine if it's a real problem or not is to get a hold of a proper oil pressure gauge. I would suggest buying one to have in your car permanently, but if that doesn't appeal, then just borrow one.

also, oil pressure at idle is not a major concern. I would be more worried about what the oil pressure is like at 3000rpm and 5000rpm.

yep just checked and it does have a oil light which is good! but i have yet to see it come on..im due for a oil change and concerned what oil to try...thinner or thicker? 5w to thin? stick with 10w? also i mite try putting a dif oil pres gauge on the car and check it thru that...do i do this wen its hot ?

sorry i didn't see what u wrote about the oil pressure at 3000rpm..it rises well above half way on gauge once i start driving it again but drops really quickly once i back off!

[Beer Baron]

yes that is normal. pressure rises as revs rise, and falls as revs fall. the faster the engine is spinning, the faster the pump is spinning.

as long as it's over 4 bar at 3000rpm i would not worry too much. and yes, all readings should be taken when engine (oil) is hot. 10W40 is fine.

i thought the same thing about my skyline when i first bought it...

"ah shes a little low on oil pressure, must just be the sender"

i said to myself

then BANG

[Guilt-Toy]

hahahhaa owned.. you sure showed them

was your oil pump faulty ??

[andylaurel]

yeah i thought the guage was faulty

but it turns out, it was accurate. The oil pump was faulty

[SECURITY]

my car did that once my turbo oil seal started getting worse, so it could be your turbo as well as worn bearings/faulty gauge. dont write it off as a faulty gauge without checking.

if you want to check if you've done your turbo oil seal then disconnect the piping at the lowest point of the plumbing and check for oil.

[Cubes]

Generally when its the sender some days the oil pressure will be perfectly normal then another day it will read near zero or just low generally.

I've seen mine sit perfectly on zero, then just as I looked down it had a spazo and jumped quickly to 5 (~3000rpm) and was then perfect for the next week until it had another small spazo and began reading low again, then as usual it goes back to normal soon after.

If its constantly reading low I would be concerned and definitely get it checked. If its 'looks' like a stuffed guage get it checked anyway.

Or buy your self a $100 oil pressure gauge and know your self for sure.

[sinistaGTR]

yeh my pressure was low when my turbo seals went.....

[HRthirtyone]

dude get a decent aftermarket guage on there. I WOULD be worried, but thats because i have had a low reading like that, and everything else was fine, no oil consumption, good power etc. but cost me $$$

your much better off if you rebuild the motor before it does any damage in the bottom end

well ive just done a oil change i used Penrite SIN 15w-40w wanted to go something a lil bit thicker..oil pressure hasnt gone below 1/4 and ive been given it a fair bit..seems to be running good.but im still pulling my hiflow off and gettin it all checked out seals etc.
