opus Posted June 16, 2023 Share Posted June 16, 2023 I have a good driver but it has piston slap. Belt apparently broke. Do I bother putting rebuilt heads on it since it has slap? Quote Link to comment Share on other sites More sharing options...
lmdew Posted June 16, 2023 Share Posted June 16, 2023 What's the mileage? Piston slap is not a huge problem. Does it go away when up to temp? I'm sure GD has more info for you. 1 Quote Link to comment Share on other sites More sharing options...

Do I bother putting rebuilt heads on it since it has slap? Piston slap can be fixed with the heads off with new pistons or if you have a shop that will knurl the pistons for you. With heads off, unscrew the piston pin access hole, pop the pins out and the pistons come up through the bore where the heads were. What larry said. I wouldn't worry about normal piston slap. And I'd wonder if it was reasonably maintained, and how much oil it was consuming. Edited June 16, 2023 by idosubaru Quote Link to comment Share on other sites More sharing options...
opus Posted June 16, 2023 Author Share Posted June 16, 2023 No oil consumption or leaks. 200k 2nd owner, very well maintained. It goes away 90% but pretty quiet warmed up.. Quote Link to comment Share on other sites More sharing options...

opus Posted June 17, 2023 Author Share Posted June 17, 2023 I'm having no luck finding heads without getting borked. Where's a good place for valves, seats, guides? Quote Link to comment Share on other sites More sharing options...

Numbchux Posted June 17, 2023 Share Posted June 17, 2023 Are you asking about replacing heads because the belt broke? If so, just have a machine shop replace the bent valves. The heads are fine. Quote Link to comment Share on other sites More sharing options...

Ask your local Subaru service department where they get their machine shop work done. The ones I know mostly avoid machine shop work entirely but they still always have a job or 5 they need something done for by a machine shop.

opus Posted June 18, 2023 Author Share Posted June 18, 2023 I found heads. Everything for me has to be online. Any machine shop, parts yard, etc is 150+ miles away. Quote Link to comment Share on other sites More sharing options...
