ok, the gsr i just swaappped in my da went to crap, cylinder 2 has 0 compression. all otehrs are bout 200 +... ok so i am going to rebuild bottom end with just some rings/bearings/bolts. tope end i want to do valves/springs/retainers... do i need to replace lifters and how do i check if they are bad. i obviously need to do head gasket.... net hing else while im down tehre, i jsut want it to run like new. do i have to get teh surfaces planed? its a 2001 gsr motor so im not sure if i have to get the surfaces planed./... ne others. thx lemme know. and a good place to get them for cheap would be nice too. tahnks!

 

You should get some higher comp pistons while your at it.

 

before you go off tearing off your motor do a valve adjustment some how the valve are open a little when they are suppost to be close causing them to show up as zero compression usually if a motor go back the cylinder would at least show 50psi.

 

so try a valve adjustment first? ok no prob i will when i get home, it shows now psi and the cylinder doesnt fire at all. will do. thanks for the tip
