[SCG] oil filter

[Frank DuVal]

Interesting. When I toured the Buick engine plant in 1988, as part of 
the tour (done for the Buick Club of America), we watched a worker 
installing oil filters on turbo 3.8L engines. They used a set torque 
pnuematic wrench to tighten them, so he offered us the opportunity to 
install some oil filters as the engines went past his station. Several 
of us installed oil filters. Why did I mention this? The oil filters 
were black.
