BC (before computers) we had portable billing terminals that were about the size of a portable typewriter. They had two cups on top that would secure a phone -- landline, of course -- handset. Kind of like the TTY terminals for the hearing impaired. We could send messages between terminals; that was our early email utility. Obviously no Internet.

It sounds like I am going to want to hear this story.

Maybe I will PM him and have another cup of coffee. The garage floor is pretty cold this morning.
There’s about 12 pages about pulling one O2 sensor towards the end of his build thread, it was just a couple weeks ago. In the end there were no threads left to screw the new one into. :signs8:

Ha, yeah, I PM'ed Tony and he filled me in.

I just did a final undercarriage wash to try and get it as mud free as possible, and with it warm and clean (as can be expected), shot all four with liberal amounts of WD40. After it cools a little will tackle exchanging them. I bought a cheap set of O2 sensor sockets off Amazon with various offsets, etc., hopefully will make the swap a little easier. I am still trying to get my head around what the torque equivalent will be on the weird offset ones, if I have to use them. :)

I would recommend a penetrating oil like Aerokroil or PB Blaster instead of WD-40.
Actually I saw a test somebody linked here and Aerokroil did worse than PB Blaster, and WD40 did slightly better than PB Blaster at loosening rusted bolts. I’ve been using WD40 forever and find it works at least as good as PB plus it’s good for lots of other stuff.

SO...transmission has to go back to the shop again, shifts real nice if I get on it at 3k or more, at lower rpms around 2k it's flaring on me intermittently, not a big deal I know they will take care of it appears to be some kind of gremlin. just annoying.

So this will be twice back after the rebuild? That’s not promising I have to say. :mad:Hopefully they figure it out so you don’t keep having issues, probably something simple.

He said they will get it dialed in were married now lol, they just have to find the gremlin
it pulls pretty nice if I give it full pedal I have only taken it up to about 120 since I got it back last time but she gets there nicely but piddle ******* around at 2000rpm it does wierd shit. so it seems to maybe be pressure related? I don't know

After my seized head bolts disaster on my outboard I threw my PB Blaster in the trash, totally useless, stinks, makes a mess. @07Burb not sure he is having any luck with a seized bolt on his truck he is fighting right now either. :mad::mad:
