Danno,

Were the mechanics you talked to Porsche mechanics? I've been racing for 4 years and doing DE's for 15 years and I've never had to rebuild an engine for wear. I had to rebuild my 2.7 for a cracked crankcase but there was so little wear on it that I didn't change rings or valveguides. That engine had about 12 race weekends on it and 85000 miles.

If the engine has good compression, good oil pressure when hot, and doesn't burn oil then there is no reason to suspect it needs a rebuild. On the contrary it sounds like with all the oil changes you may have a very long time before you need to rebuild it.

911 SC engines are the least stressed and longest lasting engines you can get. Remember that this basic engine was turbo charged to rediculous power levels in the 935 and would run in 24 hour races.
