Haha yea i've realised the massive difference now, I've now bolted the valvetrain back on, as I turn the engine it is slightly difficult and I can feel the compression and hear an air hissing noise, if I wait for a while after this hissing, it is easier to turn, this is the compression isn't it? and not piston hitting valve?
Ok! Now onto my next thought, the thermostat!
As you can see here there is a plug with two branches that I am pretty sure go to the stock carby.
As I am using a Holley 180 downdraught carb I don't think I need these two vaccum(?) lines.
Is it ok to leave these unplugged or should I buy a new thermostat from an earlier model corolla that does not have this plug hole, I think the early model KE55 had this type of thermostat
