Hello and welcome. My name is ***** ***** you for visiting the site. .Let me just say that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating. .The fact that the pin is facing down is not a problem, the crankshaft turns 2 times for each one turn of the cam. It is just on the compression stroke as opposed to the exhaust stroke. The problem is that the tensioner has come out, which is why the chain is too short now..The actual procedure for replacing the head or head gasket is to remove the front cover. I can't say that I have always done that myself though. Sometimes, you can take a long prybar with an angle at the end and push the tensioner back in to get the cam sprocket back on but you have to be careful of the guide that is right above the tensioner, please see diagram that is attached to the post..Otherwise you will have to take the timing cover off. Thanks.Please don’t forget to rate the answer in a positive way, . EVEN IF YOU HAVE A SUBSCRIPTION ****THAT IS THE ONLY WAY I GET PAID ****
