Hey guys

Have abit of an issue here, I'll run through quick details so can have an idea where I'm at.

Have just done a reco on an standard rb20det, had a hone, rings and bearings.

Had the head checked and recondition, had a few leaky valves, so spent abit having it all sorted out.

Had the lifters out while

Sent it away, soaked and pumped most of the old oil out of them cleaned them abit. then soaked then in new oil and pumped them in container of new oil

Prior to install.

Engine is in, and have the covers off trying to get the top end pressurised and pumped with oil.

Appear to have pressure, oil Pump is working fine. Have even pulled the sensor out on the block, and pressurised it from there with oil few times while cranking it over by hand.

Not really seeing the oil or much oil making it to the head or through the lifters yet.

I'm constantly checking by pushing down on the top of the buckets to see if they are still soft, and most/almost all still press down easy enough unfortuntely.

What are your thoughts on the situation, will I need to Pull the front off and cams back out to try bleed the lifters up and re-install?

Thanks for your input

The lifters won't bleed up solid by just cranking alone, it needs to be started. I don't know what rpm the starter cranks at but it's slow, that's why you see very little oil collecting in the head.

      Thank you for the links. I’m going to go with the 6pin plug you used. next step is rust treating re painting dash support bar and steering column then the 6pin cradle plug when it arrives in the mail.

      I don't how much the car makes a difference or whether it is just a question of gearbox and clutch. On mine it's fine. Pull type Nismo coppermix twin (standard, not competition) on the 5 speed in my Stagea. OEM slave cylinder. Bite point is a few cm off the very bottom of the pedal. Clutch pedal all the way down to put in gear, and when heading off at the lights, there's a tiny bit of nothing and then it starts biting. And fully engaged before the pedal is all the way released. There's a bit of play at the top where the pedal does nothing anymore. Are you in Australia @ck_chino? If you are set on using a Nismo slave cylinder I have one new-in-box at home. Ordered it together with the clutch but didn't get it fitted. We can work something out if you want it

      I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and  then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down.  I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far.  Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.

      Oh for sure, I'm just recounting my thoughts 😎 I'm not what you've got there to fuzt with.... likely my first idea was on the money -- rebuild or replace connectors. You can get a lot of connector stuff here  -> https://www.rapidcables.com.au/ Didn't look in the boot of mine, because I replaced these when I renewed the pump (plastic of connectors had gone brittle) edit: what I used... https://www.efihardware.com/products/2120/Deutsch-DTM-Connector-Kit-6-Pin ...cheaper... https://www.ebay.com.au/itm/364900039138

      In no way was i suggesting it’s your fault mate. The trailer cable has a plug that I removed. I will have a closer look, but I did remove the trailer wiring cable with the tow ball as I don’t need it on my silo. i have replaced the fuel pump already there’s no need to remove the cradle again I can see the wire colours from it in.
