Weak retainers?

This is about what you can see with the valve cover off (56K warning): http://www.yogipatel.net/archive/images/ca...21/Image039.jpg
This is what you see without the cams/followers (no 56K either): http://www.yogipatel.net/archive/images/ca...21/Image041.jpg
I would think to measure the valve stem clearance (if that's the best way to check), you'd need to pull the cams/followers.

At least I think it's an E clip. It's hard to tell in the pictures and I haven't seen the valve train in person yet. So, I'm not sure.

It's no e-clip. The valve is held in by a pair of grooved valve stem keepers or locks.

Thanks, I'll take a look at them tomorrow. Hopefully I'll be able to see them well enough without taking the cams and everything out.

You'll either see the radiating cracks or the retainer itself will 'dish' ever so slightly. If you look at the retainers in the picture, they have a 2 tier shape. The 'dishing' will be evident by a distortion in this shape. This 'dishing' causes the keeper to loose its grip on the valve.

Did you ever get misfire codes and CELs ? I would think that if the valves weren't sealing, you'd get some warning before total failure.
and Spooling, you can pretty much see the condition of the retainers without taking the cams off or the rockers. Well I should say most of it.
What you will look for is cracks spreading from the middle out, this is where most of the load is placed on the retainers. And if you do see a crack look to see if the valve is a little sunk, like the valve stem, and look at another healthy retainer/valve to compare height.
The keepers are strong enough.

Thanks a lot for the info guys.
