how frequent have your oil changes been.
old oil will get gummy and make bad deposits blocking oil galleys etc. a good indication would be look at your old head under the rocker cover. is it really gummy with grit etc. or is it lightly colored with oil stains etc. this would kinda let you know how it is through the rest of the engine. how did you feed your turbo from the grommet on the exhaust side if the block(series 2 Rb30) or a t piece from oil sender under intake plenum? chances are if your gauge aint working and your getting no feed it could be blocked oil gallery on sender side.
Good luck bud

c pic for reference, very dirty head not many oil changes

hay nath thanks 4 the reply head wasnt bad i just took it of due to the exhaust threads were stuffed and couldnt do up my top mount headers enought so swaped head now the oil prob ? blocks all good recently been rebulit so iam not shaw maybe i might have 2 prime the pump ? my feed line is coming out of the feed hole on the passangers side of the block an thats not blocked ?i think its seris 1 rb 30 just a stockey but still runs 17 18 psi no probs freak motor illd say

[detox_nath83]

hmm weird... possibly the oil pump impeller has shit itself... i feel its quite unlikely though....you should not have to prime the oil pump.
I know this is stupid but hows your oil level. rb30s take approx 4.7 litres and are known to hold a bit top end
whats the condition of the head u put on it. possibly oil galley blocks?? or not possible ??


if the rb30 block has the bung on the passanger side for oil feed and a larger one under it above sump for return as well as a water feed bung for turbo. then its a series 2 block.
these were not featured on series 1 block therefore you had to drill into a galley or t-piece off the oil sender.

head was sweet that i put on made shaw of it and the block dose have the drain line under the feed line and the water at the back end but i dont need the water line its a after market turbs just oil feed had another go at it but it still not pumping oil so i think its the pick up so looks like iam takeing the sump off

so your getting a trickle through your oil feed hole?

remove your oil sensor just behind the oil filter and see if anything pumps out

your blocks oil gallery runs along the drivers side, you then have a shaft running between piston 3 and 4 to your oil feed (this runs in line with the oil filter)

if you are not getting much out of both then your problem is at the oil pump or a block in the gallery from the pump to the main oil gallery


you say you have been running the engine with 18+ psi is the oil pump the turbo or na one? might be pushing the limits of possible na one and its gave up just before you decide to change heads

[madd50]

yeah thanks man thats what i was thinking shes stuffed its just a stock vl motor lol just an experemnt ive got a vt cluby just playing around with the vl but it got me stuffed i expected it to stuff up but it was going sweet just had to sort out the external waste gate not shaw how they work i do but dont its a top mount setup t4 lol then i took the head off now no oil presure stumped and ive just got a gauge comeing out the sender side into the dash i no on the vn v6 you have to prime the oil pump so gather i try the pick up or change the motor i got another 1 there but this block looks better

[detox_nath83]

basically a vacuum line is fed from compressor side of turbo to wastegate side port. once the psi in the vac line/intake gets up to wastegate setting say 12psi it opens wastegate so exhaust pressure is purged b4 the turbo and keeps the psi at a limit. then u can have a manual boost controller inline b/w compressor and wastegate to adjust the pressure in the vac line(but manual boost controller will not adjust below the spring setting in the wastegate) so if its a 12 psi spring in wastegate the manual boost controoler will not work under 12 psi only over it (there is your wastegate lesson :P)
Catchin' what im throwin'???

[madd50]

yeah thanks man thats what i thought just wasnt shaw theres a few was to hook em up thats the way i got it setup now you can also hook boost to both ports witch makes the gate stay shut a lil longer due to greater presure so ive heard
