Turbocharged400sbc Posted October 24, 2006 Report Share Posted October 24, 2006 this is how clean 5K mobil1 oil changes are...after 81,000 miles on the clock the LIM gaskets were fucked...really bad, go figure switched to prestone green antifreeze after a thourough flushing...(flushed before and after) did a bit of cleanup to the intake but nothing major...
