I have coolant leaking into the oil pan through the timing chain housing. When I took off the timing chain cover and examined it, the leak seemed to be coming from back of the timing chain tensioner. I took off the chain and the tensioner, I found coolant leaking from the holes that the tensioner attaches to on the timing chain housing. Why? Is that a problem with a cracked block? The head is new and so is the head gasket. The tensioner is new. I checked the water pump and it has no leaks. What can the problem be? It is an 2.4L quad 4 LD9 engine. (Dual overhead cam)
