How old is the battery? (Nissans are renowned for being extremely voltage sensitive).

Have you had the injectors cleaned? (Maybe 1 or more injectors stuck slightly open by gunk).

Replace the spark plugs (after you solve the current problem).

      RB25DET Engine Oil Dipstick Length

      By DraftySquash · Posted

      Hey everyone!!  I've noticed that whenever I do my oil changes, after putting 4L in, the oil level sits at the top mark in the dipstick. This is after letting the old oil drain for a very long time too! I've checked the oil level daily for the past few mornings. It happens every time and it's confusing because all the threads say that it should take about 4.7L (With some just adding the full 5L) My next thought is to figure out if the dipstick I have is correct so could someone please tell me the length of the RB25DET engine oil dipstick?  I've checked images of some of the genuine dipsticks, but none of them have the length in it. https://justjap.com/products/genuine-nissan-engine-oil-level-dipstick-fits-nissan-r34-skyline-c34-stagea-c35-laurel-y34-cedric-gloria-rb25de-t-neo?currency=AUD&srsltid=AfmBOortQXofgmiHVRKuIaiKuygL4k0Ewp68c3isGZk0vvKOJ7Yqf3iB However.... the engraving on the genuine ones say 05002 while mine says AA000. This makes me believe that maybe I have a wrong dipstick? I just want to confirm before I buy a new one. The car is a fresh import from Japan so I don't have details of the previous owner to ask him. Thanks in advance 🙏🏾

      Sport. I didn’t rebleed it cause I just removed the slave and left connected.    I will change line and slave and see how it goes.

      Did you get the sport or track ? From what the documentation says the uniclutch has a small amount of movement to disengage.  So your story of tricky pedal setup seems common.    Hopefully you got it bled up too, as the bite point moving around is usually either plates wearing in or air in the line.
