i have about 400 miles on the new build

d16z6 with a toga hv oil pump

at startup i have pretty hihg oil pressure.. once the car warms up 190-200ish

it gets low..

at idle its like 10-15 give or take

and at wot 65-70

when its starting to warm up i have 80psi all day long but once i get to 180 deg it just gets low..

is this cause maybe my bearing clearences are big?? or what im running 10W30 cheap **** to break it in.. tuning this sat gonna put some Amsoil in it what weight shoudl i run to help my pressure>? and is my pressure ok?

Topdawgg

those Idle and WOT numbers are normal...

THEDirtyDseriesWOOT

cool well what wieght do yall recomend running in Amsoil oil

dunkd

10-15 at idle is low in my opinion.

When I was running 10-W30 I would idle at 10-15psi. Swapped to 10-W40 and got it up to a steady 20psi. It idled much better too.

i know it isnt a gm, but the general says 10psi for every 1000 rpms, so idle at 750, 7psi is considered normal. are you running race bearings? where the clearances? thou? thou and a half? 2thou? the looser the lower.

THEDirtyDseriesWOOT

yash im running race bearings.. but i dont know the clearance ill have to ask the machine shop whom built the short block

THEDirtyDseriesWOOT

noones replied i wanna run amsoil oil what wieght should i run

i am going to slightly TJ this topic but i a have almost the same issue mine is lower though, bump for oil weight question

i thought it was my oil pump?? strange...

It depends on how hot it gets there in the summer. You will want a thicker oil if it gets hot and a thinner oil when its cold outside. You could go with a 10w-40 or a 20-50. If you go with the heavier oil and it gets cold outside make sure you let the car run and idle for a while before you go smash on it....

highrev1987

it is pulling this psi at 40 F

Ya I was talking more about the OP. Your probably sounds like it might be a little bit more serious if its much lower. Not leaking any oil anywhere? Is everything stock or lsv?

highrev1987

its a boosted d16z6 no leaks no smoke...

sorry again for the thread jack

95GSRTT

Low on oil at all? If not, yes I would definitely check out your oil pump, What gauge are you using to check the oil pressure? Possible its off?

highrev1987

autotmeter mechanical, oil pressure is perfect, i do feel a slight pulse in my clutch pedal ( i know thats strange) could it be a HG

95GSRTT

If it was a headgasket I would think you would be seeing smoke or a leak, so I highly doubt thats it. Eh just take out the gauge so you never have to think about it

THEDirtyDseriesWOOT

autometer guage here also.. yah im thinkgin of goin 20w50 it gets hot as expletive here.. louisiana

highrev1987

yeah that would work for high heat, i am near philly its icy here, its good for Intake Temps
