See if you're getting fire. My timing chain jumped a tooth. It still ran, just really rough. If you just took the valve cover off about all you could see is if the chain was still on; if it jumped a tooth you couldn't really see.

set your crankshaft to TDC with your valve cover off. Your camshaft sproket should have either a dot or three dots below a link which should be the one at 12 o' clock. The link that is above the dot or dots should be a different color and/or say something different on the actual link than all the others. If your crankshaft is set at TDC, the dot on the camshaft should be at 12 o clock, if not go around again with the crankshaft pulley until they are both lined up and the special link is above the dot, this will only take up to 3 more times going around until the link is lined up, if it isn't already. If the dot on the cam sprocket is off from the link by one, then you know you are off a tooth.

I have heard that if it jumps a tooth there will be a slight suction at the exhaust. You could try having someone crank it while you check the exhaust pipe for any kind of slight suction.

Hey Thanks everyone for your replies...I fixed it! My Distributor "unspooled" looked like an explosion took place inside. Took about 30 minutes to install a new one...back on the road again!
Thank you all again
