2004 Subaru Impreza TS
If I am already having the head gasket repaired,
and I am told that there is an issue with some of
the pistons, about how much total should that
cost to fix it? Is it worth fixing? It only has about
115, 000 miles on it.
What is the issue with the pistons? Do you need a full rebuild?
Most likely the valves collided with the pistons and damaged them. Since engine is already open, it shouldn't be that more expensive but it really depends on how many pistons were damaged.
Installing new pistons, rings and bearings and doing it right will easily be a couple of thousand more.
