We finally found why my dads truck had an intermittent misfire. We had our new plugs and wires on it but it would still miss occasionally. I had noticed that the driver side valve train was making a lot of noise. We pulled the valve cover off and found a broken valve spring. The outer spring was broken in half and the inner spring was broken in three pieces. Luckily my dad had some extras for it laying around and we replaced it no problem. I also took a video of it running without a valve cover on it. I figured you guys might like the video. I’ll upload it in just a bit and post it here when it’s done.
Very interesting. Good info to have just in case. Thanks for the pics and vid man!

Believe it or not those rocker arms have a lifetime warranty. They were made by comp cams but sadly they don’t make them anymore.

That’s odd of comp to drop a product line like that.

It turns out that they just updated the design. I guess that these were the pro magnums and now they are the ultra pro magnums. They still offer a lifetime warranty though.
