Engine noise

Hi Patrick
Did not. Wives have a way of making those lists....
The list of cars I need to look at is growing. Daughter informs me the ac on my truck that she is driving is not working and the Mustang threw a code I now need to check. In my mind the cobra should be first on the list. I think I need to tell them I keep the cobra, everyone else rides a horse. I will let you all now about the cobra when I get a chance. Inquiring minds want to know. Thanks.
Bob

Bob, did you ever get a chance to eyeball the problemo on your engine?

Patrick, you won't believe it, but I just took the day off to attend to it. Popped the driver side valve cover. As I was pulling it off I heard the same tinny noise when the engine was running. When I removed the cover a piece of sheetmetal had detached under the valve cover. It looks like it is some kind of baffle that was spot welded to the inside of the cover. It was lying right by valves 6 & 7 which is where the niose was. I would think it is supposed to redirect oil spray back onto the rockers. Don't know if I need to replace the cover or if I can get it tacked back on. I'll see if I can figure out how to upload some photos of the valve cover and the metal piece. While I'm in there, I'm still going to check the lash, but this explains why the driver side was noisy and not the other side. Also, valves 5 & 6 were noisier than 1,2,3 & 4, but not as bad as 6 & 7. The metal piece was concentrated over 6 & 7, but still impacted 5 & 8.

Man, what a GREAT 4th of July present. That's essentially a "nothing" fix. Hurray.

Depending on the type of aftermarket valve train you may have, clearances with the valve cover can be tight. The internal baffles on original style valve covers often need to be clearanced...
