Nope. All retainers that I have posted are cracked and from the exhaust side (save for the one on the far right. That one I just used as an example. I dont know what side its from.

Me too! I just got it back today. It drives excellent. It might just be my mind playing ticks on me but I think I hear reduced valve noise after the repairs.

So, doesnt this go against everything that has been said? I thought the intake retainers were the ones that failed? Makes me wonder if yours was an independent issue...

Could be. Id be worried about taking it to a mechanic that got that mixed up though. Any way to tell confrim T6? Difference in design perhaps?

all the retainers & cotters are identical for ap1 intake/exhaust.

the ap2 are identical intake/exhaust but obviously a different design from the ap1.

if he's a normal honda mechanic i'm sure it'd be easy to switch it up since in most cases the motor he's working on would be mounted sideways

Nope he took pictures to show me. If he still has them I guess I could post them. You can see in the picture the exhaust valves are sitting a hair lower than the others. He was 100% sure they were exhaust valves.

I could very well be the only one that had broken exhaust valves. However they are broken.

Milage doesn't matter. What matters is if the engine was EVER over REV-ed. The retainers can be cracked, and then just break at anytime (even during normal driving)dropping the valve into the cylinder.

What are the signs? I know that taking the vc off and inspecting is not good enough. Is there any specific sounds?

Your best bet is to actually look at them. Check out this pic from s2ki:


Good one is on the left, bad on the right. See how the retainer on the right is working it's way down the valve.

Thank you so much that is great info and pics. Can I inspect them properly still on the car easily? With the combination of visible cracks added to my inspection?

I think there is a camshaft in the way.

Pull the valve cover, and inspect the valve height near the keepers.

Should be able to. Once again a pic from s2ki. Good on the right, bad on the left.

I had all 16 of my retainers replaced this summer after dropping a valve. Luckily it did not drop into the cylinder, just bounced up and down against the cam shaft.

Anyway, I had four with cracks in the end but the thing is you cannot see the crack unless you take the retainers out as the crack is always on the underside and once you have done that you may as well replace them. Parts are cheap, but a few hundred in labour. With an AP1 I say its money well spent for piece of mind

I know the parts are cheap and I am scared that they are cracked for sure.

Has anyone on here done the job recently?

What do you rate the job personally in difficulty?

What is your background/experience on a car?

That is not definite to me...

I can barely tell which one is bad?

yes
pretty easy, but somewhat time consuming
very extensive.

you have to take your time to do it right. additionally, you should modify the spring compressor you get before you start. it can take awhile to get correct and it's pretty much impossible to do the job without cutting it up.
