Hi guys

In the process of putting together a 2530 and just trying to make sense of some of the info in the oil restriction table. I want to retain my VCT. I will be using an N1 oil pump and RB25DET head (circuit/drift application) so according to the table, ill be blocking off the front feed and inserting a 1mm restrictor in the rear feed in the rb30 block. My question is, what is it referring to when it states to leave the VVT supply?

Theres obviously no provision for a restrictor in an RB30 block for oil supply to VCT so i was a bit confused. I still haven't decided whether i want to do an external oil feed to VCT or the brass plug mod on the front of the head. But once i chose, that'll be it to ensure function of my VCT aside from welding up the oil feed in the head, yea?

The VCT oil feed returns via the head, so it is effectively a head oil supply as well, remembering the purpose of the table is to prevent high flow oil pumps filling the head (and emptying the sump).

You will need an oil  supply for the VCT, I'm not familiar with the various options

I would recommend going for an external oil feed for the Variable Timing Control, I've tried the internal brass plug way and it wasn't pressurising the VTC enough.  I had a new plug CNC'd with the correct hole sizes and it still didn't work, external worked perfectly.

Appreciate the feedback guys. External vct oil feed it is then. 

In regards to the oil restrictor table, that would count as "leaving" the vct supply, correct?

So i can follow it as recommend and block the front/ insert 1mm in rear?

99% sure from memory that's what I did but might have gone for a 1.2mm restrictor with a 26 pump.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
