If I plan on NOT using the Variable cam timing,

do I still need to feed the VCT with oil?????? by means of external or the 'new' internal method i have read about......

In all the threads I have read they show ways to get oil to the VCT but no ones talked about if you are not using the VCT does it still need oil run to it or not?

I believe the oil being fed there may also lube that front cam journal?

Also i noticed that the large hole located near the Original VCT feed in the RB25 head is a different size/shape to the RB30E block. Does this matter? will it seal?

is anything done? which head gasket is used?

Thanks for you time!

Regards,

Andrew

headgasket suits the block,

everywhere i have read suggests that u need to still feed oil to the vct to keep the front cam journal lubed, i however did not supply any oil to the vct. i got some advice from a good drag mate of mine who has done 6 or 7 rb30det builds in many road and drag cars and none of them have had oil supplied there and he has not seen a drama yet.

as for the different shaped hole in the head, u do need to weld up the difference, or drill and tap the small hole in the head and insert a grub screw otherwise oil will mix with your coolant (not good)

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
