I ordered a new timing chain from phil along with a tensioner and some oil rail parts for the cams. Yesterday my son and I rolled the chain on with no problem.

I have not replaced the tensioner yet. I rolled the engine around once and got the timing mark on the right cam zeroed. The left cam mark looked the same as before and the crank balancer marks were exactly the same as they were with the old chain, seven degrees past zero.

Please give me your opinion on what the problem may be.
