Ferrari Mailing List: Re: Engine Rebuild III

[Michael James (cavallino_rapante]

My mechanic, David Feinberg, believes my choice in oil coupled with the heat 
did some serious damage - the piston rings scoured the cylinder liners, and 
vice-versa when the oil 'broke-down" from high-heat, and the bearings in the 
motor are all SHOT.  The Cams and Crankshaft were spared, but the bearing sets 
have risen in price over the years....and so have cylinder liners.  I also 
burned-through a piston.  I also have all of the engine gaskets to replace (a 
whole-set of engine gaskets are $1,800, which include the head gaskets).  All 
16 exhaust valves are destroyed, along with 9 intake valves.....the previous 
valve job managed to 'nick' all of the valves and corrupt their sealing 
properties, so my compression/leakdown numbers were horrible across the board.  
I suppose I should be lucky that the Block and Heads were spared, but the 
internal 'bits' that have been roasted over the years....crap!
 
Anywho, we'll have to sit-down and review what the way-ahead looks like.

As Bill famously said, "I feel your pain."  In my case a TR first gear 
repair, a crown gear carrier upgrade, and a ridiculously expensive 
throwout bearing replacement.  Kind of like the restaurant price guide 
-  $$$$$.
