Value of 3.0 with blown piston
 

1980 SC 3.0

Tensioner update

Turbo Valve covers update

Air box update with bypass

New Alt and Accum within 30 miles

clean engine

miles on engine 42k as the title says (but could be more?)

come on someone has to throw out a value?

How 'blown' is the piston and was it the result of some other problem?
I took apart a 3.0 with a piston that went and the following was UNuseable:
- 1x head
- 5x cylinders (broken piston parts scored most other internals)
- 5x pistons (see above)
- 1x rod (bent when piston ate itself)
- Crankshaft (piston failure was traced to a oiling issue and rod bearing failed)
- Oil pump (damaged by rod)
- Oil cooler (thrown out due to the likelyhood of small metal bits getting everywhere)

In fact, I was very lucky to salvage the case and a few other small internal pieces. If I was to put a value on a 3.0 engine with a destroyed piston again, I would plan on only being able to use 5 heads, the cam towers, cams, fan/alternator and some of the front timing stuff - maybe $850-1200. As a reference point, the 3.0 package I got cost $2500 and included clean Webers and a fresh reground crank.
