Yeah take it off and block off that little hole.

And to make it hold even more, "adjust" up the spring tension by crushing the top of the bov in a vice. too crush it even more, tap in the top too a rounded bowl shape. It'll be super tight now, and will be able too hold your desired boost.

This is the hole to block. Use a screw/tape/hot glue/whatever.

It can be crushed to about this height. It'll collapse in it's proper order, just let the vice do its work.

Tap it on the top and round it inwards for even more tension.

You may experience flutter under certain conditions. Usually only under light throttle back offs when under boost.

I just crushed it till I felt it stop. I don't know if you can get solder to stick to cast. I used some tape folded over a couple of times.

You'll feel it when it can't crush anymore. The nipple will touch or bottom out and may bend a little.

im gonna try n find something to block the hole off now and use my uncles vice tomorow and put it all back together. is there any downside to this or should i be all good?

Just make sure whatever you use isn't going to get sucked/pushed through.

Use a piece of wood with the vice to crush it.

You can use a ball pein hammer or a hammer and shifter to round the top in.

The only negatives could be the flutter that everyone argue's about. It only happens when you back off the throttle lightly when under boost. Gear changes and sudden back offs it functions normally.

It flutters under that condition because of the tighter spring tension, and the vacuum isn't able to pull the diaphragm up. Any aftermarket BOV does pretty much the same thing anyway.

i tried the fan case screw. the actual thread is not tight in the hole but the head of the screw fits perfect. what i dont was put teflon around the screw and put thread locker just underneath the head of the screw. if that dosent work il try somthing else

I've came across a few different sized case fan screws.

These are the type I used - http://www.pccasegear.com/category83_1.htm

Unsure if they are identical to the ones I have but thats what they look like.

They were very difficult to screw in as it was very tight they were also super tight when screwing in to a computer case fan.

    • Nah, they'll do it without a receipt, tell em roughly when it was, that it was cash, youll likely only get store credit, but that gets you some dollars towards the newer better shovel, or other item you need/want later.   Still take it back and have a crack at returning it.
    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
