Read the oil control thread. Beyond all the talk about restrictors and external drains, there is solid info on the best sort of closed circuit catch can system. Open catch cans and deactivated PCV is a shit idea.

Why is this?

Whats the issue with the PCV being blocked off?

Street legality = zero.

Fumey smells = the suck.

It not being hard to actually achieve a multi stage catch can with proper pcv functionality = enough of a reason to go to that amount of effort rather than cheaping out.

As long as it wont damage anything thats fine.

Only reason mines like that at the moment is because im such a cheap ass i havnt got a place to attach it into my intake

That said, ive never had Smells or Smoke coming from it.

yer its just my highmount set up doesnt have a spot on the intake pipe to add that third line

That's a weak reason.

You havee been asking about getting someone to fab a catch can.

Get them to add it to to the inlet pipe.

^ Cal ya show off :)

Had to be done lol. I dunno people seem to get mental about catch cans but mine works alright for a mild-medium setup lol. Plus I like my photo :)

and as above, I have a fitting welded onto my intake for the catch can. The bungs can be bought easy as, theres no problem at all sourcing them. It would cost bugger all to have it welded on. If he is making a catch can I dare say if you supply the fitting he will weld it on for free

That's a weak reason.

Thats a fair point. I just bought all the lines and fitting for the car and the can it was coming with feel through. so now im stuck with a heap of fittings nd braided line. hence trying to find a fab guy so i can get it made to exactly how i need it

My tuner blocked my pcv up saying it causes problems with the nistune

Any truth to that, or is he seeing a placebo affect?

yep, with any AFM setup if you're introducing "un-metered" air from the atmosphere it will cause all sorts of issues.. hence if you're running an AFM setup with a vented catch can you need to delete the PCV

    • Very nice - I also have a 92 GTST and hardly see any others around these days
    • When I need something else to edit, I use Movavi. A friend who does video editing on a daily basis recommended me) it's an easy video cutter to use for beginners
    • I need to edit some videos for work but I'm not good at all this. Which video editor can you recommend?
    • I think you're really missing the point. The spec is just the minimum spec that the fuel has to meet. The additive packages can, and do, go above that minimum if the fuel brand feels they need/want to. And so you get BP Ultimate or Shell Ultra (or whatever they call it) making promises to clean your engine better than the standard stuff....simply because they do actually put better additive packages in there. They do not waste special sauce on the plebian fuel if they can avoid it. I didn't say "energy density". I just said "density". That's right, the specific gravity (if you want to use a really shit old imperial description for mass per unit volume). The density being higher indicates a number of things, from reduces oxygen content, to increased numbers of double bonds or cyclic components. That then just happens to flow on to the calorific value on a volume basis being correspondingly higher. The calorific value on a mass basis barely changes, because almost all hydrocarbon materials have a very similar CV per kg. But whatever - the end result is that you do get a bit more energy per litre, which helps to offset some of the sting of the massive price bump over 91. I can go you one better than "I used to work at a fuel station". I had uni lecturers who worked at the Pt Stanvac refinery (at the time they were lecturing, as industry specialist lecturers) who were quite candid about the business. And granted, that was 30+ years ago, and you might note that I have stated above that I think the industry has since collected together near the bottom (quite like ISPs, when you think about it). Oh, did I mention that I am quite literally a combustion engineer? I'm designing (well, actually, trying to avoid designing and trying to make the junior engineer do it) a heavy fuel oil firing system for a cement plant in fricking Iraq, this week. Last week it was natural gas fired this-that. The week before it was LPG fired anode furnaces for a copper smelter (well, the burners for them, not the actual furnaces, which are just big dumb steel). I'm kinda all over fuels.
    • Well my freshly rebuilt RB25DET Neo went bang 1000kms in, completely fried big end bearing in cylinder 1 so bad my engine seized. No knocking or oil pressure issue prior to this happening, all happened within less than a second. Had Nitto oil pump, 8L baffled sump, head drain, oil restrictors, the lot put in to prevent me spinning a bearing like i did to need the rebuild. Mechanic that looked after the works has no idea what caused it. Reckoned it may have been bearing clearance wrong in cylinder 1 we have no idea. Machinist who did the work reckoned it was something on the mechanic. Anyway thats between them, i had no part in it, just paid the money Curiosity question, does the oil system on RB’s go sump > oil pump > filter > around engine? If so, if you had a leak on an oil filter relocation plate, say sump > oil pump > filter > LEAK > around engine would this cause a low oil pressure reading if the sensors was before the filter?   TIA
