FYI,
buying 32 valve keeper is not going to be cheap...
u can use magnetic to keep keepers from flying out.

32x $1.64 = $52.48 =Cheap to me.

Titanium, while light, is also pretty soft. It WILL deform over time (like billman said, about 15K miles).
This is what I'm talking about. Everyone claims this, yet Honda uses Ti for the NSX rods? It just doesn't add up and there is nobody here that has had a Ti retainer fail.

PM Venomous S to join in here. He has done lots of research on Ti retainers. He runs them.

Bought a Compression Tester today (mainly for the spark plug air compressor hookup) and rented an overhead valve compressor from Autozone. It looks similar to the one above but I won't know if it will fit until I try it I guess.

connecting rods are under different stresses than valve retainers. titanium is actually a good metal to use for rods.

Well, the job is done. The short of it is that 3 retainers were cracked, one of them in 2 places. At least another 4 retainers were dished. Also, the valve stem seals looked worn on the inside (the plastic part), maybe I should have replaced these...

I'll post pics when I get home.

I, too, am on the verge of replacing my retainers.

I am leaning towards purchasing '04 retainers. Does anyone know if the '04 is a direct replacement for the ap1 retainers (any modification needed to make the '04's fit/ work)?

I was interested in the Ti retainers, but the thought of them failing and the possibilty of having to replace them after ONLY 15k miles is disheartening.

I am curious, to see the pics of your retainers fyrestrike.
