Hi!
When cold my oil pressure is about 4 bar or ~60psi
When warm i get 2 bar ~ 30psi
After driving the car and when oil temperature reads 100-110C my oil pressure can drop to 1.5-2bar at 1000rpm

If the RPM's are 2-4000 the pressure is constantly at 4 bar 60psi-ish but it wont rise above that @ higher RPM's

Castrol edge 10w60 full synthetic

My logic says it should rise above that @ higher rpm's, I will check the pressure with analog gauge and try to put the stock sender also in there to get multiple readings in a few hours.

So should i remove the oil pan and put some more washers in the pressure regulator at the rear iron (i already have 2 in there)
Or should i put some washers in the front cover regulator also? but i think it starts working over 100psi stock, so no difference?

Or can it be the problem with the front cover o ring leak, that i do not get more pressure when driving 4-7k rpm?

Any help will be appreciated, wanna solve this ASAP!

Thanks!

 

you're overreacting, your oil pressure is RIGHT where it should be

 

so it is normal that it won't go over 4 bar? it will eventually be about 400HP engine. will it be enough?

 

10w-60 seems quite thick but your pressure is fine. If you are concerned about it being too low you can get the FD pressure regulator for the back and shim the front regulator like most race engines do. However, that much pressure isn't needed on a street car and usually is for race only applications where clearancing and race rotor bearings (larger oil grooves) are used

 

thanks man! this kind of answer i was looking for
but i think 10w60 is okay with rotary, same pressure like the 10w40 was.
I actually measured the pressure directly with a manometer i got from work with the same thread as pressure sender. The vdo sender shows 1 bar less, just in case i checked with another manometer and it had same reading as the first one. So i guess everything seems to be fine.
