Jesus!

Who setup your catch can?

PCV is still in tack, but you've blocked off the breather line to the intake pipe!

How is the fumes suppose to be sucked out when the plenum pressure is +ve?

Plump it back so the 3rd line off your catch can is going back into the intake pipe!

haha...

I set up the catch can so that could be the reason why it's wrong?

Currently, the 2 hoses off the top of the rocker cover is going to the catch can and it pretty much ends there, venting to the atmosphere. The previous hose back to the inlet has been blocked off.

I always thought that was what was suppose to happen so oily air is not introduced to the engine again?

Should I route one line back to the inlet? ie, the catch can has 4 points, 2 in from rocker cover to the top left, 1 vents to atmosphere (bottom line) and the other (top left) I should route back to inlet?

Thanks in advance and thanks all for confirming S2?

I checked the timing belt/cam cover and there's a lump on the left side facing out. This is S2?

Its a S2.

In regards to the catch can, seems fine to me. I have mine set up the same.

PCV intact because blocking it caused blowby,

Rocker covers vented to an atmo venting catch can, and the breather --> intake line blocked. Was told to use that by a very knowledgeable SAU member too.. Been fine for me.

Looks like its still plumbed, but in the line that goes from exh. rocker cover to the intake i put a custom alloy bung where the brass restrictor was.

Edited by gotRICE?
So its a Series 1.5? Did the 1.5 come with a series 2 motor or has everyone in this thread with a 95 had an engine swap?

Series 1.5 came with series 2 motor. Also has the higher sitting series 2 spoiler (the one in your avatar). As far as I know they were all 1995.

Hey johnnillicte,

My current setup seems to be working fine. Although what you have said seems to make sense too. What are the benefits of plumbing back into the inlet (beside legality). Will it scavenge more from the rocker?

What's everybodies thoughts? Quite a few mechanics have seen the engine bay but no one has commented, surprisingly?

Cheers,

J

On idle the PCV will open up and stuck air from the cam covers into the plenum, saying that, it will be also sucking in from the vent you have on idle. This will disrupt engine idle as this air isn't being read by the AFM

If you have the catch can plumped back into the intake, on boost you will be drawing more blow by out of the cam cover as it will "suck" from the cam covers.

To further enhance the efficiency of the catch can, just fill it up with steel wool.

    • I believe there was a similar one posted by @duggyphresh. They were re-routing their battery positive cable in the way I am also trying to achieve. Sorry, I’m new to this forum, so was a bit late to the party by a few months and so reignited the old thread, as I wanted to know how they got on with doing it.
    • Wasn't there a thread on this very subject just a few weeks ago?
    • Hi all! Looking to relocate the battery to the trunk of an R34 GTT. I want to do it using as many stock GTR components as I can (including the harness protectors from the 34 GTR that run underneath along the chassis to the engine bay). So far I’ve purchased the battery tray from a 33 GTR, as the captive weld nuts are already there just asking to be used. There is also the slight issue of now having to relocate the ABS/TC/Fuel Pump Control ECU, which in GTT’s sits right above where the battery will then sit on the tray. Has anyone already achieved this, and if you have any pics that you wouldn’t mind sharing? It would be great to see how others have done it and where you put them, as there are countless holes in the parcel shelf panel to potentially use. Just trying to get some ideas bounced around, and to help uncover any potential problems I may encounter by  my choice of location. TIA for any help!
    • Brand was ard.   I also threw a brand new battery at it and beefed up the wire from the alternator to battery and added an extra earthing point from the battery 
    • Evening all,       I'm replacing some bolts on my RB25 with probolt Australia bolts.       Does anyone know the following, m5 m6 etc 10mm 20mm etc       Coil cover   Cam covers   Plazamaman fuel rail   Front cover (timing cover)   Etc   Any help would be awesome   Or any lists anywhere
