Hey Kevin Johnson - are you from crank-scrapers.com? I ordered a crank scraper for an FJ20 from you in 2012 and you never sent it, and then you started ignoring my emails...

Has anyone seen or used mines cam cover baffles with no foam ?

i Have mines cam cover baffles but without foam (was like that since previous owner built the engine) and also my friends uncle imported a 34 Gtr from japan built by JUN many years ago and he said his was the same

pros and cons of this ? Should I be adding the foam in there ? 

Also im not sure if the stock metal gauze/mesh is in there either

Well, obviously, if you have nothing in there to keep the mist in the engine the mist is going to flow to your catch can setup and you will have to deal with an increased amount of oil - whatever that "dealing with" entails.

They should have foam in them and if they don't they will still "work", for a given smaller value of the term "work".

The standard mesh was quite unimpressive when i opened up a cover

I took advise from iruvyouskyrine and did the fuel cell foam method, havent started the car yet but its got the old oil blowing motor back in it so will be a good test.

Well.... Dyno just finished on my forged rb25det build. Fitted a blanking plug on the centre hole and left the other 2.

It now has noisy lifters above 5K rpm and gets worse as it revs. Oil pressure is spot on. My tuner said to never use restrictors in a hydraulic lifter head as he has seen this before... 

Lesson learnt, never take advice from this page without discussing with professionals.... FFS....

I can't see that as a recommended option in "the table"

How does he explain why so many other people (including me) have fitted restrictors / blocked oil feeds, and haven't had noise problems?

Additional restriction is a thing when the oil pump has been upgraded.  Not just a "because" thing.

Learnt my lesson mate, only have spool pump gears and a collar so no need for a restriction at all..

Did exactly what it says on the table. Have you always been a flamin mongrel or do you still have bits of your mum stuck to you from birth?

Which part of the table did you follow? I can't see any of the options that say to leave the rear feed as is.

You'll make lots of friends here dude - good luck with your engine..... FYI my mother died a few months ago - so lets hope we meet up one day and I'll rip whatever is left of your mother off you, you fcking arsehole.

That table would probably be better with 1.25 restrictors instead of blocked off for the standard pump cases.  That would include the N1 pump, because it's really not that much larger (if at all) than a stocker.  Neos have the N1 pump, for example.

I used to sell restrictors and often for hydraulic lifters including my own RB30 with an N1 pump and external fed VVT ...think it was 2 x 1mm from memory but was years ago and my memory is fading.  Joe Kyle built the RB30.
