Ok, engine is back together after replacing the head gasket but when I started it there is a "clackity clackity" sound coming from the engine. I don't think it is the valves hitting the pistons as the engine turns over by hand smoothly. Other than the "clackity" sound the engine sounds fine and smooth (good exhaust not, runs smooth).
The sound is almost like noisy tappets of old.
Could it be the lash adjusters needing oil pressure? The cams, and therefore the rockers and lash adjusters, never did get removed when I changed the head gasket and the head was off the car for over a week.
The Chilton manual I have says that, when replacing the lash adjusters there will be tapping when first started. Let the engine warm up, then rev to 3000rpm for a minute, then stop it and let it cool down. The tapping should have stopped at next start.
Considering the noise I'd feel real nervous doing that.
I'm assuming you changed the oil before starting it back up, if not do it now, as there is probably coolant in it and that is BAD for the motor, and could have easily messed something up in your head
It sounds to me like it's not getting enough oil or the oil has coolant in it and not providing enough lubrication, but I would try what the chilton manual says after you eliminate the above mentioned, my buddy had his off for over a week and his didn't chatter at all like that when he put them back on
