    Hey man! You might be able to contact ZZP and get 1 of the 1.9 rockers/pedestals/bolts replaced. They have done that for me with lifters in the past.

    Great presentation. Will be working on a 4 cylinder head soon. Would like to know how much air pressure you use to check for bubbles.

      I used about 85 PSI. You can always go a little bit higher.

    I learn so much from these videos ngl, I’m debating on doing all the things your doing just in a black car. With a little more time and money I wanna pull my heads and do exactly what you’re doing. Still gotta find that intermittent misfire tho, still confused by that one.

    For a novice a manual valve lapping stick would be the safer option imo

    Question. It is recommended to lap the valves that arent leaking (lightly) for cleaning purposes? I would have to have it all pull out just to address the ones leaking, put it all back together and in and then a while later the good ones start leaking cause it finally was enough?

    • @The3800Daily
      @The3800Daily  7 місяців тому +2

      Of course you can! Most definitely lap valves that are not leaking. That's called preventative maintenance. If you noticed, I lapped all the valves, even the ones that weren't leaking in the first place. 👌

    i mean yeah its a good way to find a leak but lapping with a drill isnt for beginner builders use the wooden lappin stick that has multiple size rubber cups on them and build up lappping over mulyiple attepts not all in one shot because of the chance to mess up the seat or over do the depth...

    • @The3800Daily

      This compound is mainly for removing carbon contamination from the valve seating. It's not abrasive enough to really cut into the valve seats enough to make depth changes
