]Well got around to installing my catch can on the weekend and i went with this set up. Can any one tell me if this is correct way of doing it and if its working properly ? Any thoughts would be great. Car seams to be running fine but has a miis under boost but i think that due to plugs or coil packs cause just went on the dyno and had boost turned up . post-78172-0-11146500-1295788660_thumb.jpg

Yeah that's got the PCV catered for, but you can also run the valve cover breathers to it too.

It's prob better for the engine to vent it to air instead of back into the intake, but it's not very legal that way...

Pretty sure that won't work. You still have it set up so that oil and oil vapour can be sucked into the intake side of the turbo, particularly under boost (high load) conditions. And that is exactly when you don't want it to happen.

The PCV valve only opens under high vacuum (low load) and detonation from the oil vapour isn't a problem.

Yeah but then you have to vent it to atmo which is not legal.

How is that different to how hes done it, still has the PCV and plumbed into the intake?

edit: my bad I thought he had done it like you had, you are right that is the better way to do it. When on boost it sucks the gasses via the catch can, when on vac it sucks straight out the cam covers avoiding oil in the turbo.

His is the opposite, when on vac it sucks via the catch can, when on boost it sucks the oil straight out of the cam covers into the turbo.

thought i might of f#!!ked it. So what u have done is plumbed the catch can between the cam cover and the pvc taking out that pipe all togeather? did u notice a difference? will hook it up ur way just means bigger pipe and larger barb ends on the catch can witch will be a bitch to find. Thanks for the pics mate.

No you don't!

Here's mine, stil complying with the requirement to have a fully sealed system not venting to atmosphere:

and you always run those hoses that close to the fan????

Thats better, you'll pass an epa/defect inspection with it set up like that as well.

I would have used black hose under the intake piping personally, but its functional at least.

nup still to close for my liking, I especially like the black electrical tape holding it in its 'safe' position... come on really you couldnt find a safer place to have them or is that all the hose you could afford...

yeah i know it stands out a bit just a quick install got to fly out for work tomorrow so got some hose and fittings on order for when i get home plus don't really like the brass fitings i used. It won't stand out so much then. thanks for the advice guys.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
