I searched and read a lot of great info on timing chain issues. But I still have a question
2003 Explorer 2wd, 4.0 SOHC
I had lots of noise in the front of the motor. I found the Dr side cam chain very loose. Changed hydraulic tensioner. The chain it was tight, but still had noise. Pulled the timing cover and all of the guides had wear, and the bottom tensioner was broken in pieces. There was chatter marks on the inside of the timing cover. All guides and tensioners were replaced which involved pulling the oil pan to get to the bottom tensioner and remove the pieces in the pan.
There is still noise. It is less pronounced and hard to locate. I may be coming from the rear chain but it is very hard to pin point even with a mechanics stethoscope.
Is there a good listening method to determine the noise is the rear chain. I don't want to go through the time and expense of pulling the motor to get to that thing if is not the issue.
