Hello all
I have read through this topic and noticed that members start talking about adding in restrictors. Is this pre assembly and an alternative to welding?
I only ask because I have a RB30 in car, It has been in the 33 for quite a while (2004ish I want to say). The car has been off the road for around 3 years now though and I am looking at getting it back to its former glory days. I found this topic and could not really find a reason that I am unable to perform this now with the motor still in the car and remaining assembled. Yes there would be some mess to clean up, But that's not really a huge issue.
That was until the talk of restrictors came up.
Originally when the motor was built the oil feed in question was welded off due to the water feed being below (could be the other way around, It's been along time ). The pictures above are confusing me a little, in particular "Drill your oil feed (Picture taken from underneath the head)" and "Tap a Taper thread into the head oil feed, and grub screw it nice and tight.". I apologize if this is just morning stupidity.
In my head I don't need to consider these two steps and just stick with the original pull, drill (2mm & 1.5mm), plug and enjoy VVT again.
Is this correct?
Thank you for your time.
