New here, longtime Miata and Toyota person. Found a 98 Forester "with early signs of rod knock", otherwise a very nice car w/ 170k on 2nd engine. All this as per owner as I won't see it till next week. A bit of research tells me these engines are prone to rod knocks and head gasket issues. And from what I gather not the easiest engine to work on or pull. I am well equipped and very mechanical, yet I wonder if this is worth bothering with. I know some cars aren't worth it for free. Opinions? Sorry no photos but car is Red, not leather seats, auto trans, AWD. My previous experience was decades ago with an indestructible 1982 AWD Subaru manual wagon which ran forever and put up with terrible roads with no problems.
