5.0 mystery trouble
Reply #25 –
To be honest the customer did not OK the repair or should i say the inspection. Timing chain is my feelings as all the cylinders are app the same compression pressure or reading. A stretched chain drops the compression evenly because the cam retards several degrees. This points to a stretched or jumped chain i am assuming. I once found a cam pin missing years ago on one. That was a KILLER. But what i was trying to point out was a simple compression test was all it took. The reason the balance test was ok and would come back all ok is the cylinders are all the same or close within 10%. And in my experience the ford roller motors never eat cams. What i should say is i never saw a flat roller cam in a FORD. So i was pointing out that some people just run codes and never go back to basics. A dozen shops overlooked this issue . So sometimes the old fashioned trouble shooting pays off. Thanks and your posts were excellent. Once the customer Signs a work order i will post further findings. Thanks So much for being good sports Tom!!
