first engine= bolt sheared on alternator bracket belts came off and went in the cam belt.

second engine= complete 4+4 engine burnt a valve (too much boost)

third engine= rebuilt the 4+4 engine spun the shells after 75 miles (caused by lint off a rag collecting at the pick up pipe strainer)

fourth engine= rebuilt the 4+4 engine again melted three pistons after 1200 miles (caused by a shit greys chip with too much ignition advance)

fifth engine= rebuilt the 4+4 engine again block cracked after 5k miles

sixth engine= rebuilt again using a 205 block no problems at all and used up untill 2 1/2 years ago.

seventh engine= this is my current one.
