Overfilled Engine Oil 1.5Cm Above Max Mark On Dipstick

[rondofj]

Hey fellas yesterday I did an engine oil n filter change (used GW SYN-X 3000), i drained the oil out for like 15-20mins, there still was a constant tiny trickle out from the sump which is impossible to get rid of. Then I did the filter and topped up oil from the 5L bottle leaving like 100-200ml in the bottle. My dipstick shows fresh oil like 1-2 cm above the max mark.

Should i be worried n drain some out????

Engine oil press while driving is normal 2kg/cm sq and up to 6kg/cm sq when boosting hard..

run the engine for 30 seconds or so, turn it off, let it sit for about a minute and then check the oil level. if it is still well over the max level then you could drain a bit out. if it is about at the full mark then it isn't so much of a drama.

I fill up all the way to the hump above the H mark, anything inbetween the hump and H will be fine. Beyond the hump I would worry

Dose anyone know the exact amount of oil for the rb25det. I've search and found so many different answers i'm confused.

Wow 5L for RB25DET- i always thought it would be around 4.5-4.8L reading here on SAU..

4.8lt ususally gets me to the hump almost...

[babyskyline]

My rb25det was always about 4.7 ish so every engine can be a little different.

i always put the full 5 litres in now, it always shit me wasting the tiny bit at the end

over filling slightly wont cause you any problems

i dont really see how over filling could cause any problem at all?

There is alot of space between the hot mark on the dipstick and the bottom of the crank on RB26s (room for about 1.5-2l of more oil), which is why we overfill to the hump. But when oil does hit the crank from, the crank whips it up like butter and it foams up, also creating crankhouse pressure which can blow the rear main.

wow, big diff between rb26 std and n1

[ahhbee]

dont overfill it to much, i poped the rear main seal on my r34 with the oil level at the hump (granted it may not have been the cause but its the only thing i can put it down to + shitty factory breather setup). n1's extra oil capacity is due to a factory oil cooler i think.
