Canadian redneck

New to the site, but wonder if anyone can help. Just over heated my 85 toyota cuz my temp guage doesnt work and ive been fiddling with a few problems lately on it. seems to be shooting coolant out over the #4 piston at the gasket. seems to be running on 3 cylinders cuz its sputters n wont run well under load. does fine in neutral so im assuming ive toasted the gasket near the rear of the engine. anything i should look for as I take it apart to tell me whether i need a new block or head or if I can jsut change the gasket?? timing was off cuz i jsut finished doing the timing chain and was playing around with the distributor.

if it is the 4 banger then that is a tough little engine so you should be fine. You can have the head checked to make sure it did not warp.
