• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    "Connecting to activate.tapatalk.com..."

    I put the thread title in quotation marks because that's exactly how it appears in the status bar at the lower left of my screen. The browser I'm using is Firefox and it's constantly tries to connect to tapatalk. It only happens at GrandPrixForms.com. What I do is manually click the stop load...

    Rocker Arm Bolt Thread Sealant

    I'm assuming that old dried and hard thread sealant should come off before reinstalling the bolts. I tried threading a 5/16-18 nut onto the rocker arm bolt and the nut hits a brick wall when it gets to the thread sealant. A hand wire brush does not put a dent in it. Should I try soaking the...
