<VV> Wireing needs continued

[jvhroberts at aol.com]

 Viton was around for about a decade when the caveman cars were introduced. 

True, the HRPT was a part that outlasted any warranty issues. But a REAL fix was truly a penny fix. The other things you mentioned are not worth it, blower bearings generally last a good long time. OHC would've been a ridiculously expensive fix, Viton O rings aren't, and GM spent PLENTY on replacing O rings under warranty, so going cheap here was NOT worth it. 

BTW, the so called 'modular engine' apparently had warping issues by having that big honkin' chunk of relatively cool aluminum to eliminate push rod tubes. Again, Viton sealed engines NEVER leak because of O ring deterioration. None of my Viton sealed engines ever leaked!

I don't think Viton had been invented when the Corvair was first introduced (I may be wrong, though.)


?


Further, GM never had $200,000 worth of problems with their terminal block. So the money saved was a good move on their part.

Note that?I'm not excusing using only an "adequate" part instead of a superior part. Rather, just explaining the economics of it. One might also argue that they should have done a lot of other things as well, like design the engine with overhead cams, so that there wouldn't be leaky pushrod tubes, OR design an easily changed blower bearing, instead of one that required a significant engine teardown and a pressed-out-pressed-in specialty bearing. Or any of a myriad of other merely "adequate" designs to be built on a?mass-produced?economy car.

for the added 80 cents, to NOT have problems, is money well spent. 

Same reason as to why GM didn't offer Viton O rings as OEM.

And Clark's sells his C6802 junction block for $3.20. That's an 80 cent

savings, times a quarter million vehicles...... Hummmm. That's a $200,000

savings. No wonder GM went with the cheaper alternative.



And YES, GM is THAT cheap. My dad was a bean-counter for them, and he

always had to figure things out to the tenth of a cent (for that reason-

economy of scale).
