My first car was a '70 Nova w/307 V-8. Must have over heated bad once or twice before I bought it. The o-rings put around the valve stems got hard, brittle and started breaking about the time I got the car. I ran a can of Rislone thru it because I was using a quart of oil every 500-600 miles, ended up using a quart every 250 miles afterwards. I finally found a mechanic that agreed with me where my oil was going, past the valve guides. I had him replace the o-rings on the valve stems. I drove the car 400 miles using no oil, then used a quart in 500 miles, then a quart in 200, and finally ended up using a quart every 125-150 miles. Valve guides were wore and I chewed up o-rings just like the mechanic said I would.
I checked all the local salvage yards for either heads or complete engines. Not much of a selection and expensive, so saved my money to trade cars. I went the last year without changing the oil, just spun on a new filter every 4-5 months and added more oil. I carried a case of 24 quart steel cans of oil in the trunk, whatever was cheap.

An improperly torqued capscrew on an engine head or a shear bolt that is too hard on the driving shaft of a bushog can create havoc and make an expensive and uncalled for repair. Let�s examine the purpose and design of these fasteners in order to ensure their proper use. Fasteners are probably one of the aspects of mechanics that is given the least amount of thought.
