The gasket blew out on the timing cover and began spraying coolant everywhere. I have removed the timing cover and discovered a lot of slack on the timing chain. I have a new chain set, but I didn't rotate the engine to TDC before removing everything. I was only planning on replacing all the gaskets. The old timing chain is still in place, but since I am replacing it and neither the crank or cam have moved, can I just install it in the position that it's in? The cam dowel and crank key will keep it in the same relative timing.
