so it turns out that after i pull the head. the #2 piston is shot. I can't find a size on it. other than a number 3 by itself and a number 5 by itself, both on top. anyone know if i am able to buy just a single piston anywhere or does anyone have a used decent one. i suppose i will buy a set if i have to, but just trying to be cheap. cylinder wall is smooth fortunately. i don't know how though. anyone have any suggestions on who has the best gaskets and bearings. the Local Toyota dealership said they can only get a head gasket.

I'm in the process of doing the same thing! I am replacing the #5 piston. I have good compression an the other five cylinders and my valves look good. A local cruiser shop is helping me with getting a new piston and rings. They are ordering it through NAPA. As far as what size to get, they measured the diameter of the piston and looked up the stock diameter in the Haynes manual. Mine happened to be about .020 over. I'm just going to hone the cylinder wall, drop the new piston in and call it good. Obviously this is not the ideal method of repair but I've talked with a few people who have done this and have gotten several good years out of their engine. In my opinion it's worth a try considering the cost of a rebuild.
From what I have read on this board about gaskets Toyota is the best option, especially for the head gasket. I have also heard good things about Felpro gaskets. Good luck and let me know how it turns out!

Motors just dont work like this. it is a stopgap measure at best but generally you will have a 100% blown motor very soon. The time, labor and money to replace one piston is just not worth it for little or no long term gains.
dukester: Just how do you know your valves look good? Did you disassemble them and measure? How about a leak down test.
Dont polish the turd.
