In the day to day grind of a repair or restoration shop, parts are replaced and discarded without a second thought. If parts are available, which in most cases they are, replacement makes sense- the costs of restoring or rebuilding a component generally outweighs the cost of a new one. Inconvenience to all is lessened. It makes sense, right?
I tend to be nerdy about this stuff and I tend to be green, too. If I can rebuild it or repair it, I want to almost every time. I hate waste. Why waste a new part when the old one can be like new with a little work? In the early days of my journey into this field of work, the transition between rebuild and replace was beginning. Technicians were craftsman...they were rebuilding and repairing parts daily. Not so much to save their client's money but because it was the normal way of doing things. I learned that way. I accepted that way of thinking and still practice it in my daily work.
Oil Line Repair
While performing some restorative work to a 1977 911 Turbo, I was shocked to find that the oil pressure hoses connecting both to and from the scavenge pump were not available. My natural approach was to rebuild them. No problem- solution found. I rebuilt the cam feed lines, too. Here are some pictures of my repair.
This situation called for line rebuilding for a few reasons: 1. The vehicle's owner didn't want to upgrade to hydraulic chain tensioners. 2. he didn't want to replace the lines with 'new' looking lines that were zinc coated. He wanted to retain an original appearance.
This worked out nicely for the turbo feed and scavenge pump lines, too!
