I haven't researched the oil pump gear replacement, but from what I hear here, it's not as involved as a rebuild, nor as much cost. Sounds like the way to go.
I did see another post on here where someone had a picture of new metal oil pump gears?? Who sells them?
I'm not looking to do a Big Bore unless I was going to have to tear it down to that extent anyway. It doesn't sound like that's the case. And again, I'm more than satisfied with this little hot rod as she is. I just want to make her well again.
As for what seized? Great question, and with any luck at all, I might not ever find out.
Metals in oil sample aren't bad, but bearings might be a concern if it trends the way the last sample indicated.
For what it's worth, I have heard good things about that Polydyne TX7. That surely didn't hurt. It's a coating, and doesn't "wash out" with an oil change, hence only having to use it periodically, and I may be overusing it at that. Whether I used it or not, it was never reflected in an oil change sample. I had a friend that had given me several quarts of it, so I had nothing to lose. I've never bought any, but did see it on the accessories shelf at a Toyota dealership priced at about $40/qt. several years ago.
If I can source the metal pump gears, that sounds like the course I'll take.
Thank you all for the questions and input. This forum has come through again.
Now where again do I pay to support this fine forum?
