Re: Best race valve material

Good point. People have found that just using a torque plate while cutting the seat makes a difference. I was reading of a builder's heavily-ported Alfa Romeo 2.0 L. After doing a 'perfection' valve job and assembling the head, he stood it with ports up (can't remember if it was intake, exhaust or ...

Re: Ford's Mystery Fix Explained

Even being economical with the words, listening to someone read off a screen is painful and boring because the average person (a recent ex-president excluded) speaks ~125 words per minute but reads double that or more. At the end of a speed reading course I took decades ago, I went from 400 WPM to ...

Re: Radiation in Houston’s Tap Water

That reminds me of people saying, "that tastes like shit."

Hmmm, and you know that how ...?

I think in another area of that citation it mentions that when the body breaks it down one of the by-products is methanol. Poorly distilled homebrewed alcohol will get you that way too.

I looked everywhere and never did find where MTBE was harmful. It probably can be drank if you can get by the bad taste?

Re: Freightliner (Daimler) predicts end of diesels in big trucks,,!

I want to say that I read somewhere a time ago of people that had not seen dark nights for a long time because of the constant flaring off of Nat'l Gas in their country. I want to say someplace in Africa. It finally got cost effective to catch the stuff and sell it is what happened so their nights ...

Re: Help me understand Hydroboost/brake issue

Are we are talking HB seals?----not MC seals right? so power steering/hydraulic oil only ? Sorry about that. The power steering fluids (mineral oil based) can cause swelling of brake seals (glycol or SF based). https://drivinglife.net/brake-fluid-in-power-steering/ My negative experiences were arou...

Re: Help me understand Hydroboost/brake issue

Be sure NOT to expose the seals to a solvent other than the correct brake fluid. It is amazing how much they can swell if this is done. That could easily cause a seal failure.

Re: Ford's Mystery Fix Explained

Since WE are on the topic of Ford screw-ups, how are they doing with the 12,000,000,000 or so(??) little cars with the bad trans in them they sold before killing the transmission, IF Ford did indeed stop making/selling that transmission design?? Their Focus and Festiva cars if not mistaken?? Seems ...

In the old cowboy movies, I always wondered how it was that a posse of 12 pursuing a single bad guy could stay in a tight group for miles and still not lose any ground to him. Drafting? :-k
