98 Sable Engine Noise

[Chris Hill]

If you would, please view the youtube video listed below.

This is the same 98 Sable with DOHC Duratec engine I was asking about last week. The issue last week was the fuel pump and the fuel pump check valve just after the pump were both bad. I put in a new pump and module yesterday and it now runs after 18 months sitting.

It runs now, but makes a bad ticking/knocking noise and I think it is comming from the front valve cover area. It definitley is dependent on engine rpm. I pulled the front valve cover looking for a down lifter or lash in the valve train or something obvious, but everything seemed to be ok.

I am not a mechanic by any means and I'm trying to help out a friend here, but I don't know what is causing the noise. If you could, please view and listen to the video and give me your ideas on what is wrong and how serious it is.



Thank you,

Chris
