Engine noise

Thanks for all the info. Patrickt, great summary of valve lash adjustment. I figured I would use a socket and pipe to rotate the engine. I never was any good at bumping the engine with the starter. I was going to make sure I used neoprene valve cover gaskets so I can reuse them since the covers may be off once in a while. Bill, do you know if the heads are iron or aluminum? Can't say that I've really checked them out yet. I will check the header bolts just to cover all the bases. This is what makes this forum so great. I have been reading and following things for probably two years before I bought the car. Hopefully I have the time to look things over this weekend and I will let you all know what I find. Thanks again.

Bob, don't trust Bill.

Get a magnet off the front of your refrigerator (that's probably holding up one of the kids' pictures) and put it on the head. If it sticks, it's iron, it it doesn't, it's aluminum.

Bob, beware of Patrick bearing gifts from afar

Heads are iron "Tunnel Port" heads.

Bob, did you get a chance to eyeball your valve train over the weekend? Hi-res pics are always helpful as well you know.

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.

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.
