I am with David on this one. I think the safest plan of attack is going to be a thorough cleaning of your garage, degreasing the car from top to bottom before pulling in, and once in make sure you close off all entrances using plastic dividers. Once you get the engine entirely out, which you definitely will need to do, tear it down, make a very detailed parts list, contact the manufacturers of each individual component, demand the metallurgy findings for each component, and if they don't have them, send each component out to a respected member in the field of metallurgy. Before you do that make sure you vet the people you are sending the parts to in order to verify their training and experience. That's what I would suggest starting with. If you need more info on the steps after I can chime back in.

Or we can all just keep things in perspective instead of calling the internet/s2ki police and realize that there is helpful feedback and then there is clear overwhelming information for the sake of self indulgence, half of which doesn't even relate to the immediate issue at hand, so expect some rolling eyes and goofy feedback (this is also an entertainment website) If the posters who regularly do this don't like it, Id suggest to them to try sweetening up the point or expect some less then favorable comments. There are some knowledgeable people in here, but some of them would better serve themselves and the people they are trying to help by staying on track and your track record in time will prove how smart you are at troubleshooting - IF that's the motive in providing a full page history lesson response to a one sentence question.

oops, i made this post while.. drunk. thats normally when i find time to play online lol...
update: the engine is out and i have all the parts labeled and placed according to size. whats the next step?
lol, seriously.. let me ask a more direct question:
1: can i just pull the valve cover and look to see if they are too sunk? or do i actually need to put air in the cyl, pull the cams etc to see?
2: does having JUST titanium retainers give me any RPM safety advantage over stock AP2 retainers and keepers? hitting rev limiter, miss shifts, etc?
thanks!

2.No, Ti is lighter than steel, so its a performance upgrade not a reliability one. Nothing beats the reliability of OEM ap2 retainers. If you are running after market more aggressive lift cams then you are likely running aftermarket heavier dual valve spring and the corresponding aftermarket Ti retainers are paired to work with those. If your not running aftermarket cams then I highly suggest you return back to stock valve springs/retainers and keepers.

1. Yes you can see the valve stems and top of keepers with just a valve cover removal. The issue is Ti are brittle, and my fear would unlike OEM is when they fail they fail entirely. I also dont know without looking at yours what they should look like since they are no longer oem.

Just to clarify that #2. Running ti retainers by themselves does not give a safety margin, the increased safety margin comes from the higher spring rate of the valve springs.
