Hey everyone, just been tearing down my rb25det to change a few of the gaskets and modify a few things. One of those things was adding a catch can. But I’ve run into an issue. My idiot self thought that the breathers were just screwed in.. even the slightest bit of research shows that they are intact not screw in but pressed in. I’ve already bought all the fittings for the system. So now I’m just wondering if anyone knew any good ways to remove the fittings? I’m in the Geelong area of Victoria if anyone knows someone specific, if not then just the sort of business that would be able to help me out with that?
 

My idea after getting them removed was to tap the remaining holes and possible get them welded on too? Thoughts on this are welcome as I’m sure more than one person has been through this.

Well, they are just pressed in, so they just get pulled out. You have to twist and wiggle.

I am absolutely unclear on what you mean by this. If you want to change the fittings, there are dedicated press in AN fittings that people use expressly for this purpose. Available at most places where people sell this sort of stuff for these sorts of cars/engines/projects. Like Raceworks, EFI Solutions. And eBay. And Aliexpress.

ah okay, i was mainly asking because i saw somewhere that you have to heat them up or something to remove them.

and tbh i wasnt aware you could buy press in fittings and the main reason i bought the thread in was because i though thats what the oem ones did anyway and i thought it best to try and utalise the ones i have already bought

I've recently removed mine. As mentioned if you can twist them to get them moving they come out pretty easy after that. If you're having trouble, stick something like a screwdriver or socket extension through the hole to use as a moment arm to get them spinning around.

Also as mentioned, many companies make press-in adapter fittings like so: https://raceworks.com.au/fittings/adapters/an-rocker-cover-breather-adapters/

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
