good video should have bin an rb 26 tho lol 🙂 that really new one you have ha ha

[@arthie553]

hey Colton, it’s me again lol outstanding video, and I really dig that tool to install valve spring keepers. now, regarding the valve leaping technique, I’ve heard that you’re supposed to tap ‘n twist, instead of only twist. apparently the tapping motion helps with creating a bigger contact area. do you know if that’s true or not?

[@boost.factory]

Hey John, good question. in my experience the lapping compound is working its way out in both directions across the entire face while twisting anyways so i dont see the need to tap, then when cleaned off you can visibly see the contact patch. I typically see people tapping to re-introduce lapping compound back onto the seat and valve face, then you can continue lapping. Again, you're only trying to get the surfaces to know each other. You're not trying to remove excessive material. 1 maybe 2 passes is plenty. Any more, and their is an issue.

Hi there, I'm just wondering if I can i find that valve tool. Do you sell it maybe or know where i might find one ?? Awesome video, man. i have watched your videos so many times now, and I almost know it word for word big fan of the full 26 buld to . brilliant content 👏

[@boost.factory]

Thank you for the support! we appreciate it! the tool is available on toyotool.com Toyo tool is the name, They dont have many products on their site so it should be easy to track down!

[@itsnickestevez]

Which valve keeper tool are you using?

[@blackhawk7292]

Hi! You guys might know this! What do people replace their rb25det neo lifters with? I can`t find any info about this subject? I need mine changed because the aluminium lifters on the exhaust side is worn out.

[@boost.factory]

Unfortunately the only option currently on the market is used oem or new oem. which is very expensive. we do have a cylinder head we are parting out if you wanted to email us on a used set [e-mail] hope this helps!

Do you think the valves sank from lapping and if so how thanks !

[@boost.factory]

Hey, good question! Nothing considerable. You are only trying to get the valve to know the seat again. You're not trying to machine anything down. You would be hard pressed to make a significant change in height without our first damaging the seat. The valve installed height is relatively the same as before, and the valve shim thickness reflects that!

Hi how do you remove the steel balls that block the oil gallery’s holes?

[@boost.factory]

Hey Chris, we have a pointed steel tip that we weld onto the ball, then that threads onto a slide hammer, a couple taps, and they're out!
