When the cams both point up and you lock em down with a punch...that's TDC right?
I know that much....I shoulda said the cams in relation to the pistons.dano said:No...the TDC term applies to the block and pistons.
Got it...Thanks!!dano said:But, yes when the cam arrows are up and you have them locked with punches (or something).. The indicator and the flywheel mark for TDC should be lined up. Make sure it's the TDC mark and not the ignition timing mark.
I didn't fully understand that part, but to fully answer your curiosity, I am taking off the entire head to do a head gasket. I have done it before, just never really considered the timing thing before, but never had a problem...so I was double checking to make SURE I did it right.dano said:Don't turn the the crankshaft very much and don't hesitate to turn the crankshaft CLOCKWISE if you need to in order to find the TDC mark.
In other words don't think you can ONLY turn the crankshaft counterclockwise and turn it 360 degrees..
YOU WILL BEND VALVES if you force it.
